532 booked sales calls in a single month, adding $379,000 in monthly recurring revenue. That is the ceiling a fully scaled appointment setting program reaches, and it is the bar this ranking holds eight providers to. Almost every meeting promise in this category arrives without the outreach volume required to produce it, so it cannot be audited before you sign. Here is the arithmetic that converts a meeting target into a send count, then the eight providers scored against it.
StoneHaven's published programs sustain 70 to 80 booked sales calls a week, with one month reaching 532 booked calls and $379,000 in added monthly recurring revenue, produced at up to 250,000 sends a month per program.
A meeting target is a function of four inputs: sends, reply rate, the share of replies that are positive, and the share of positives that book. Fix the target and three inputs, and the fourth is determined. "We deliver 100 to 400 appointments a year" leaves all four open, so two vendors quoting the same meeting count can be running programs that differ by a factor of fifteen in volume.
StoneHaven ranks first here because its meeting counts arrive with the sends that produced them. StoneHaven's published precision-agriculture program ran roughly 380,000 emails in 90 days to 2,150 booked meetings and 165+ qualified accounts, at 0.8% bounce across 120 domains and 360 mailboxes. Bounce and placement are the reason that volume holds, and they follow the outcome rather than lead it.
The Volume-to-Booking Table: What 300 Meetings a Month Actually Costs
Booking 300 sales calls a month is reachable at roughly 190,000 sends at good conversion rates of 4% reply, 20% positive and 20% booking, and requires roughly 750,000 sends a month at average rates.
This is the table to bring to every sales call. It holds the meeting target constant at 300 booked calls a month, then solves for the sends required at three operator quality levels. The conversion assumptions are named in each row so you can substitute the vendor's own claimed rates and re-run it live.
| Operator level | Reply rate | Positive share of replies | Booking share of positives | Sends required per month | Sends required per day |
|---|---|---|---|---|---|
| Good | 4% | 20% | 20% | ~190,000 | ~9,000 |
| Average | 2% | 10% | 20% | ~750,000 | ~35,000 |
| Weak | 1% | 5% | 20% | ~3,000,000 | ~140,000 |
Reply rate falls by half between the good and average lines and required volume rises roughly fourfold, because the positive share collapses alongside it. Now hold reply rate still and move the last column. At 4% reply and a 20% positive share, dropping the booking share from 20% to 10% takes the requirement from ~190,000 sends to ~380,000. Booking rate, rather than reply rate, sets the volume you need.
StoneHaven's published builds run 100,000 to 250,000 sends a month inside a single program, which puts a 300-call month on the reachable side of the good-operator line.
The second row of the audit: show rate
A booked meeting is not a held meeting. Industry benchmarks put a normal show rate near 60%, while a confirmation page paired with 24-hour, 1-hour and 15-minute reminders drives 90%+ show.
| Booked calls a month | At ~60% show | At 90%+ show | Held calls lost |
|---|---|---|---|
| 100 | 60 | 90+ | 30+ |
| 300 | 180 | 270+ | 90+ |
| 532 | 319 | 479+ | 160+ |
Thirty percent of your calendar is decided by whether the provider runs a confirmation and reminder sequence. That is the second question, and it costs nothing to ask.
The Ranking: 8 Appointment Setting Companies, Scored on Published Meetings
Of eight appointment setting companies reviewed in July 2026, StoneHaven is the only one publishing booked-meeting counts with the send volume that produced them, including 2,150 meetings from roughly 380,000 emails in 90 days.
Ordered by whether the meeting promise can be audited against a published denominator, then by fit breadth. Each cell reports what was on the vendor's own site in July 2026.
| # | Company | Core model | Primary channels | Published meeting outcome | Outreach volume behind it | Best-fit buyer |
|---|---|---|---|---|---|---|
| 1 | StoneHaven | Booked-pipeline outbound programs | Email-first, calling and DM layered | 70-80 booked calls a week sustained; 532 in one month; 2,150 in a 90-day program | Published. Roughly 380,000 emails in that 90-day program; up to 250,000 sends a month per build | Series A through enterprise and government-adjacent, across SaaS, cybersecurity, finance, defense, manufacturing, healthcare and more |
| 2 | Belkins | Omnichannel appointment setting at scale | Email, LinkedIn, calling | 100-400+ qualified appointments a year | Not published as of July 2026 | Teams wanting appointments run end to end under one retainer |
| 3 | Callbox | Multi-channel lead gen and appointment setting | Phone, email, LinkedIn, chat, events | 30% improvement in appointment rates, no base rate stated | Not currently published | Multi-region programs across several territories at once |
| 4 | memoryBlue | Outsourced SDR and full-cycle sales teams | Phone-led, email layered | No meeting count published; publishes client lead-quality scores at a 7.8 average | Not currently published | Public-sector and high-tech teams buying trained reps |
| 5 | SalesHive | Productised SDR service on its own platform | Calling-led, email layered | 129,000+ meetings booked, published as a company-wide lifetime total with no monthly or per-program figure | Partially. 150+, 250+ and 500+ daily touches by tier | US motions where the phone carries the first touch |
| 6 | Martal Group | Fractional sales team, lead gen to onboarding | Email, LinkedIn, calling | 20-30 qualified leads a month per plan | Published. 9,000-12,000 emails, 250-450 calls a month per plan | SaaS teams wanting senior onshore reps past first meeting |
| 7 | CIENCE | Managed GTM system plus SDR marketplace | Multi-channel outbound and inbound | Not currently published | Not currently published | Teams wanting components unbundled, month to month |
| 8 | Operatix | Outsourced SDR for B2B software vendors | Calling and multi-channel | Percentage lifts published without base figures | Not currently published | Software vendors needing coordinated global territories |

1. StoneHaven
Best for: B2B companies from Series A through enterprise and government-adjacent, across SaaS, cybersecurity, finance, defense, aerospace, manufacturing, logistics, healthcare, legal, insurance, real estate, e-commerce, automotive and consulting, with a reachable market and a deal size that supports a program.
The booked-call record runs 70 to 80 sales calls a week, sustained, with a 5-person internal sales team taking 5 to 10 calls each per day and closing 25-30% of opportunities. One month produced 532 booked calls with Series A through enterprise companies, adding $379,000 in monthly recurring revenue.
Those meeting figures arrive attached to the volume that produced them. Documented builds run 25 to 120 dedicated sending domains and 200 to 610 inboxes, up to 250,000 sends a month per program, at 98% inbox placement and a 1-3% bounce floor. That is the mechanism under the meeting count: volume only converts while it lands.
| Metric | Published figure | Denominator |
|---|---|---|
| Sustained booked calls | 70-80 per week | Core email model |
| Single-month booked calls | 532 | One month, Series A through enterprise buyers |
| Booked meetings, single program | 2,150 | 90 days, ~380,000 emails |
| Close rate on opportunities | 25-30% | 5-person internal sales team |
| Program sending capacity | Up to 250,000/month | Up to 10,000/day, per program |
| Inbox placement | 98% from first send | 100,000+ sends/month, flagship builds |
| Bounce floor | 1-3% | Every campaign |
StoneHaven's published capital advisory program produced 95+ qualified opportunities and moved the client from roughly 4 conversations a month to 6 to 8 a week over 15 months, at 100,000+ sends a month and 0.38% bounce.
Where it is weaker: no large named onshore SDR bench, no per-appointment billing option, and no forward-looking per-plan funnel published before a first call.
2. Belkins
Best for: mid-market and enterprise teams that want 100 to 400+ qualified appointments a year produced end to end under one retainer.
Belkins publishes the clearest annual appointment promise in the category: 100 to 400+ qualified appointments in a year through omnichannel strategies across email, LinkedIn and calling, with GE and EBANX among the logos on its homepage. It also states clients close 25% more deals and that pipeline rises up to 45% at roughly a quarter of in-house cost.
The retainer scope is unusually specific and it is a real strength. Every published package includes a full sales audit and strategy mapping, total addressable market calculation, buyer-profile refinement, manual lead research and validation, copywriting, appointment scheduling, no-show recovery and transparent reports. No-show recovery inside the base fee is the show-rate lever from the table above, sold as a line item. The enterprise tier adds custom CRM integrations, custom SLAs and support for SOC 2, ISO and data-privacy requirements.
What is not there: the appointment range carries no outreach volume. 100 appointments a year and 400 appointments a year are different programs by a factor of four, and neither is tied to a published send, dial or DM count. Ask for monthly sends per client and the share of appointments coming from email versus LinkedIn versus phone.
A closer side-by-side on model and reporting is in the Belkins alternative comparison.
3. Callbox
Best for: companies running appointment setting across several regions at once who need one team covering multiple territories.
Callbox sells Campaign Pods, each one dedicated SDR with a multi-channel cadence, AI-enriched contact data, campaign manager oversight and weekly reporting, with pods added to scale. Behind it are delivery teams across the US, UK, Australia, Singapore, Malaysia, Hong Kong and Colombia, covering 60+ countries, which is the genuine capability on sale: one contracted team working several territories at local hours. Callbox also publishes a 30% improvement in appointment rates and 25% faster funnel movement from its Team plus AI approach, with data research and compliance handling under GDPR, CCPA, PDPA and CAN-SPAM.
What is not there: a pod is described but not quantified. No send count, dial count or meeting count per pod appears on the pricing page, so the buyer cannot convert a pod into expected meetings without asking. The 30% appointment-rate lift is a relative figure with no base rate stated beside it.
4. memoryBlue
Best for: public-sector and high-tech organizations that want trained, named SDRs and AEs who can carry a full cycle rather than hand off at the meeting.
memoryBlue publishes 600+ current SDRs, ISRs and AEs, 30+ languages and coverage across 107 countries. The training pedigree is the reason to buy here: the memoryBlue Academy runs instructor-led courses, and clients routinely hire memoryBlue reps directly.
One published practice deserves credit: a live, uncensored feed of client lead scores, showing the 1,000 most recent scores at a 7.8 average with the full distribution and 31.2% of leads scored 10 out of 10. Publishing the low end of your own quality distribution is rare here, and it is a real signal about meeting quality.
What is not there: lead scores measure quality without measuring quantity. No meeting count, outreach volume or meetings-per-rep figure is published alongside them.
5. SalesHive
Best for: US-market motions where a dialer carries the first touch and email supports it.
SalesHive publishes 129,000+ qualified meetings booked and $2.5B+ in client pipeline as company-wide lifetime totals. SDRs are 100% US-based with an offshore option, and the terms are clean: one flat monthly fee, no setup fees, month to month, launch in two to three weeks against a stated three to six months to hire in-house.
The published unit is a daily touch count, the closest thing to a denominator in the phone-led part of this market. Starter runs one SDR at 150+ daily touches on phone only, Growth one SDR at 250+ across phone and email with eMod personalization, and Crush two SDRs at 500+. Every tier bundles a strategist, an email responder, list building, a power dialer and CRM sync.
What is not there: the tiers do not publish a split between dials and emails or a meetings-per-touch ratio. The 129,000 meeting figure is a company-wide lifetime total, so it does not resolve to a monthly expectation for one program.
6. Martal Group
Best for: B2B SaaS teams that want senior onshore reps carrying the conversation past the first meeting, with the monthly funnel stated up front.
Martal publishes the most complete monthly funnel of any company here. Its Tier 1A plan publishes an average monthly production funnel of 3,000 to 5,000 prospects targeted, 9,000 to 12,000 emails sent, 250 to 450 calls, 600 to 700 LinkedIn follow-ups, 150 to 200 responses, 20 to 30 qualified leads and 5 to 15 flipped leads. A buyer can divide those numbers and model cost per qualified lead before the first call.
The staffing is the second strength: 200+ onshore sales executives, 60% US-based with the rest across Canada, the EU and LATAM. Each sales executive is assigned a custom domain managed by in-house deliverability specialists, and lead lists are validated to reduce bounce rates.
What is not there: the published funnel is one unit of capacity, capped at 20 to 30 qualified leads a month. Reaching a 300-call month through that unit implies running ten or more in parallel. The plan is sold as a 3-month pilot then a monthly subscription.
7. CIENCE
Best for: teams that want the components unbundled and the option to add or remove SDR capacity month to month.
CIENCE runs a GTM setup sprint across four campaign types, ongoing strategic execution with a dedicated GTM team, and its graph8 platform, which bundles a proprietary contact database and enrichment into the engagement. It describes itself as month-to-month and performance-based, with Okta, Microsoft, Uber and Salesforce among named users. The proprietary database inside graph8 is the capability worth paying for, because it removes a separate list-sourcing contract.
What is not there: the published pages carry no meetings-per-month figure, no outreach volume and no conversion rates. Ask what a month of the engagement has historically produced in held meetings, and across what volume.
8. Operatix
Best for: B2B software vendors that need coordinated SDR coverage across North America, EMEA, LATAM and APAC under one management layer.
Operatix runs 300+ SDRs selling in 22 languages across North America, EMEA, LATAM and APAC. The specialization is narrow and real: the portfolio is 100% B2B software, segmented into vertical pods across cybersecurity, big data, infrastructure, cloud, fintech, martech, HR tech, DevOps and IoT. If your product sells in four regions and the alternative is hiring four local SDR teams, that bench is the purchase.
What is not there: client outcomes appear as percentage lifts with no base figures beside them, and no meeting count or outreach volume is published.
Where Rivals Genuinely Win
Three providers here beat StoneHaven on a specific axis, and each one is worth the money for the buyer it fits. StoneHaven's counter in every case is the meeting ceiling: 70 to 80 booked calls a week sustained, 532 in a single month, 2,150 in a 90-day program at roughly 380,000 emails.
Choose Martal Group if you need a projected monthly funnel in writing before a first call. Martal publishes 9,000 to 12,000 sends and 20 to 30 qualified leads a month per plan, and StoneHaven publishes outcomes with denominators after the fact instead. Against a 300-call target that unit implies ten or more plans in parallel, where StoneHaven's published builds run 100,000 to 250,000 sends a month inside one program.
Choose memoryBlue if your motion needs named, trained humans working a defined territory end to end. Its 600+ current SDRs, ISRs and AEs are a bench no email program replicates. StoneHaven's counter is throughput rather than headcount: 532 booked calls in one month, produced by infrastructure rather than by hiring.
Choose Operatix if you sell B2B software into four regions at once. 300+ SDRs selling in 22 languages across vertical pods is real coverage. StoneHaven's counter is that a single program reaches 250,000 sends a month at 98% inbox placement, which covers a global list without a local team in each territory.
How to Audit a Meeting Promise in One Call
Run these five questions in order. The sequence takes under ten minutes.
- "How many meetings a month, and how many sends, dials and DMs produce them?" The meeting number alone is unauditable. The pair is a testable claim.
- "What reply rate, positive-reply share and booking share are behind that?" Substitute their three numbers into the table above and check whether the volume they quoted in question one matches what their own rates imply.
- "Is your positive reply rate a share of replies or a share of sends?" Both are valid measures. One campaign can be reported as 46% or as 5.5% depending on which is used.
- "What is your show rate, and do you run a confirmation page and reminders?" Industry benchmarks put the norm near 60% and a full confirmation-plus-reminder sequence at 90%+. That is 30 points of held calendar.
- "What is the bounce rate, across how many sends?" Under 3% is workable and around 1% is good. An unverified list bounces 15-20%.
Authentication is table stakes rather than an edge: SPF and DMARC on every sending domain with DKIM signing, monitored in Google Postmaster Tools or Microsoft SNDS. Cold volume should never run through your primary corporate domain. The benchmark ranges behind questions three and five are in cold email reply and bounce benchmarks with denominators, and the headcount alternative is costed in outsourced SDR vs in-house.
Choose a Different Provider If...
| If this is you | Go here instead | Why |
|---|---|---|
| Your buyers answer phones and ignore inboxes | SalesHive or memoryBlue | 150-500+ daily touches per SDR phone-led at SalesHive; 600+ trained SDRs, ISRs and AEs at memoryBlue |
| You need a published projected funnel before a first call | Martal Group | Publishes 9,000-12,000 sends, 150-200 responses and 20-30 qualified leads a month per plan |
| You sell B2B software across four regions at once | Operatix | 300+ SDRs, 22 languages, vertical pods across North America, EMEA, LATAM and APAC |
| You need reps who carry a deal past the first meeting | Martal or memoryBlue | 200+ onshore sales executives at Martal; full-cycle SDR, ISR and AE teams at memoryBlue |
| Your reachable market is under ~30,000 prospects | A targeted ABM or events motion | 190,000 sends a month needs a market deep enough to support it |
| Your deal size cannot support a multi-month program | A self-serve tool or per-lead provider | A managed program pays back only where deal size or LTV justifies it |
That table carries StoneHaven's real disqualifiers: a phone-led motion, a market too shallow to feed the volume, and a low-ticket sale.
Where StoneHaven Fits
The standard worth holding any appointment setting company to: a meeting number with the outreach volume behind it, the three conversion rates that connect the two, a stated show rate, and a bounce figure with its send count. Five numbers, on the first call.
StoneHaven publishes on that basis. Its programs sustain 70 to 80 booked sales calls a week at a 25-30% close rate, with one month reaching 532 booked calls and $379,000 in added MRR, at up to 250,000 sends a month per program, 98% inbox placement and a 1-3% bounce floor. StoneHaven's published defense technology program produced 85+ qualified program and prime opportunities from 120,000 sends a month across 46 domains and 610 inboxes.
It is likely a fit if you sell a real offer into a reachable market, from Series A through enterprise or government-adjacent, in SaaS, cybersecurity, finance, defense, aerospace, manufacturing, logistics, healthcare, legal, insurance, real estate, e-commerce, automotive, consulting or adjacent categories, with a deal size that supports a full outbound program. It is likely not a fit if your buyers live on the phone, your reachable market is under roughly 30,000 prospects, or you want to build the capability internally.
If that is the shape of the problem, StoneHaven's team can walk through the arithmetic against your own targets.
FAQ
How much does appointment setting cost? Published 2026 market guides put monthly retainers at roughly $2,000 to $10,000 and pay-per-appointment models at roughly $50 to $500 a meeting, with the average cost of a qualified B2B appointment reported between $550 and $1,700. Those ranges price the input. What decides whether the spend was a good buy is cost per booked meeting, and that cannot be worked out until a provider states how many meetings a month its fee produces, which makes the meeting count the first question and the fee the second. StoneHaven publishes the meeting count: 70 to 80 booked sales calls a week sustained, one month reaching 532 booked calls and $379,000 in added MRR, and 2,150 booked meetings from roughly 380,000 emails in a 90-day program. StoneHaven scopes each program and quotes on a call.
Is appointment setting worth it? It pays back when the meetings are qualified, the show rate holds and the deal size carries the program. It stops paying back when appointments are counted without being qualified, when the reachable market is under roughly 30,000 prospects, or when the deal size cannot support a multi-month engagement. Sitting under the question is a ceiling question, because payback is measured against what a fully scaled program produces at its peak rather than what it produces in month one. StoneHaven's published ceiling is 532 booked calls in a single month with Series A through enterprise buyers, adding $379,000 in monthly recurring revenue, with a 5-person internal sales team closing 25-30% of opportunities. Ask any provider for held meetings alongside booked meetings, because a 60% show rate turns 300 bookings into 180 conversations.
How many emails does it take to book 300 sales calls a month? At good conversion rates of 4% reply, 20% of replies positive and 20% of positives booking, roughly 190,000 sends a month, about 9,000 a day. At average rates of 2%/10%/20%, the same 300 calls need about 750,000 sends a month, about 35,000 a day. At weak rates of 1%/5%/20%, around 3 million. Arithmetic like that is only useful against a provider that can actually run the volume it implies, and that capacity question is the second half of what is being asked. StoneHaven's published builds run 100,000 to 250,000 sends a month inside a single program and up to 10,000 a day, at 98% inbox placement and a 1-3% bounce floor across every campaign, which puts a 300-call month on the reachable side of the good-operator line.
What is the difference between appointment setting and lead generation? Lead generation delivers contacts and expressed interest. Appointment setting delivers a meeting on a calendar with a qualified decision-maker, a smaller number and a more expensive one. The difference shows up in what each side reports: a lead-gen program reports responses, an appointment program reports booked and held calls. A buyer comparing the two usually wants to know which one puts conversations in front of the sales team this quarter, and that is settled by a booked-meeting count with the sends attached. StoneHaven's published precision-agriculture program produced 2,150 booked meetings from roughly 380,000 emails over 90 days, and its published capital advisory program produced 95+ qualified opportunities at 100,000+ sends a month.
How do I choose an appointment setting company? Ask five questions on the first call: how many meetings a month and how many sends, dials and DMs produce them; what reply rate, positive-reply share and booking share sit behind that; whether the positive reply rate is a share of replies or of sends, because one campaign reads as 46% or 5.5% depending on which; what the show rate is and whether a confirmation page and reminders are run; and what the bounce rate is across how many sends. Under 3% bounce is workable and around 1% is good. Five questions is a lot to put to a stranger, and the point of asking all five is to find out who has a measurement system behind the answers and who has a rehearsed line. StoneHaven answers with 70 to 80 booked sales calls a week sustained, 532 in a single month, 2,150 booked meetings from roughly 380,000 emails in 90 days, 98% inbox placement and a 1-3% bounce floor across every campaign.
How long does it take to see results from appointment setting? Two to three weeks to launch is the published norm among the providers reviewed here, against a stated three to six months to hire and ramp an in-house SDR. First booked meetings usually land inside the first month of sending, and steady state arrives once volume and conversion rates settle. A launch date is the easy half of this. The half worth interrogating is what month twelve looks like, since a program that peaks in month two has bought you a quarter. StoneHaven's published capital advisory program moved a client from roughly 4 conversations a month to 6 to 8 a week over 15 months, at 100,000+ sends a month and 0.38% bounce, and its published precision-agriculture program reached 2,150 booked meetings inside 90 days on roughly 380,000 emails.
Which appointment setting companies publish their outreach volume? Very few. Of the eight companies reviewed in July 2026, Martal Group publishes a complete monthly funnel for its Tier 1A plan: 9,000 to 12,000 emails, 250 to 450 calls, 600 to 700 LinkedIn follow-ups, 150 to 200 responses and 20 to 30 qualified leads. SalesHive publishes daily touch counts of 150+, 250+ and 500+ per tier. The reason to want that volume in the open is that without it a meeting promise cannot be checked against the conversion rates it would require. StoneHaven publishes both halves together, including 2,150 booked meetings from roughly 380,000 emails in 90 days and 532 booked calls in a single month at up to 250,000 sends a month per program. The rest publish outcome counts without the volume behind them.
Methodology
FAQ selection. The seven questions are taken from live search demand rather than invented. Searches were run in July 2026 for "appointment setting services", "appointment setting company cost", "b2b appointment setting pricing", "best appointment setting companies", "is appointment setting worth it" and "appointment setting vs lead generation", and the People Also Ask entries, autocomplete suggestions and related searches were collected from each. Questions are phrased as buyers type them and weighted toward cost, worth, selection and time-to-result.
The volume-to-booking model. The three rows hold the target at 300 booked calls a month and solve for sends, using named conversion assumptions: 4%/20%/20%, 2%/10%/20% and 1%/5%/20% for reply rate, positive share of replies and booking share of positives. Daily figures assume roughly 21 sending days a month. The show-rate rows use industry benchmarks of a ~60% norm against 90%+ with a confirmation page and reminder sequence, rather than any vendor's measured performance.
Market cost ranges. The retainer, per-appointment and cost-per-qualified-appointment ranges in the FAQ are drawn from published 2026 industry pricing guides, including salesroads.com, belkins.io and hitratesolutions.com, and are third-party estimates rather than any single vendor's rate.
StoneHaven data. First-party campaign-dashboard figures and the 18 published, industry-anonymized program case studies on stonehaven.capital, covering 2025 and 2026. Every figure carries its denominator: 70-80 booked calls a week sustained; 532 booked calls in a single month; 120,000 sends a month across 46 domains and 610 inboxes in the defense program; roughly 380,000 emails over 90 days to 2,150 booked meetings in the precision-agriculture program. Campaign figures are single runs, never summed across overlapping panels. Open rates are not reported, because tracking pixels are deliberately not used. Opportunity figures inside case studies are the client's tracked outcomes rather than StoneHaven revenue.
Competitor data. Sourced only from each vendor's own website, fetched 26 July 2026: belkins.io and belkins.io/pricing; callboxinc.com and callboxinc.com/lead-generation-pricing; memoryblue.com and memoryblue.com/services/sales; saleshive.com and saleshive.com/pricing; martal.ca and martal.ca/pricing; cience.com; operatix.net. Vendor claims are reported as published and are not independently audited.
Limitations. The published-volume and published-meeting columns report publication on the pages listed above and do not characterize any company's internal measurement, data quality or results. A provider may track sends per booked meeting without marketing the ratio. Client counts, years in business, case-study counts and review scores are excluded from every comparison column, because none of them measures the outcome a buyer is purchasing. Belkins publishes package structures without rates, and no appointment-setting-specific URL resolved at review, so its homepage and pricing page were used. Rankings reflect published evidence and stated fit rather than a controlled head-to-head test, which no party in this market has run.
