Belkins alternatives in 2026: 9 agencies compared

Who Belkins is, and what they are demonstrably good at

Belkins is a B2B lead generation and appointment-setting agency founded in 2017, bootstrapped, headquartered in Dover, Delaware. Its milestone timeline records 300 employees by the end of 2022, and its homepage claims 1,000+ clients across 50+ industries and more than $2B in client revenue since 2017 (self-reported).

What they are demonstrably good at, per their own pages: omnichannel appointment setting at volume, with named enterprise case studies such as Autodesk and GE HealthCare; a documented 14-day launch with a dedicated multi-role team per account; and real deliverability depth, from building their own platform, Folderly, to publishing a warm-up ramp that starts at 10 to 20 emails per day and reaches 80 to 200 by day 14. Nothing on this page argues with any of that.

Fit-based reasons people look at alternatives

These are fit questions, not complaints, each grounded in Belkins' own pages.

• Starting price and tailored scope. Belkins' appointment-setting page lists an average starter price from $5,000, with 1,500 leads monthly, three outreach channels and a vendor-stated annual appointment target. Its plan page describes tailored retainer packages, including an ecosystem-partner small-business option. Confirm the billing period, delivery team, qualification, no-show handling and final scope in a written proposal; an advertised starting figure is not a complete quote.
• Retainer economics. Tools are "included in our retainer," per the pricing page. Buyers who want the agency's pay tied to output sit outside the published model; our pay-per-appointment vs retainer guide walks through the trade-offs.
• Yearly appointment framing. Packages are framed on 30+ to 200+ appointments per year, which suits a year-long program more than a short pilot.
• Small business is routed to partners. The For Small Business tier is "delivered through partnering agencies from the Belkins ecosystem," per the pricing page, so lean teams may not work with the core team at all.
• Full-bundle scope. The engagement bundles research, copywriting, multi-channel outreach and a multi-role team; a buyer who wants one channel done deeply may not need it all.

The branch this list does not cover: doing it yourself

Not every Belkins evaluator needs another agency. If your team can write, send and — critically — work the replies every day, the third path is contact data plus sequencing software run in-house: cheapest on paper, most expensive in staff time, and entirely dependent on someone owning reply handling. The honest cost comparison between those worlds is on agency vs in-house SDR; what the sending machine involves is on the cold email infrastructure guide.

The 9 alternatives, in order

Ordering after ReplyLead is editorial; each entry states its reason.

1. ReplyLead (that is us)

Why first: it is our list, and it is the opposite model to a retainer.

ReplyLead publishes this comparison and is a competing provider. Our model combines agreed revenue share with separately contracted infrastructure and any other applicable charges. Published infrastructure examples are $2,023 monthly at 25,000 emails and $5,531 at 100,000; these are ReplyLead planning tiers, not a universal cost floor or a complete proposal. No attributed closed revenue means no revenue share for that period, but fixed contractual charges can remain due. Confirm setup, recurring fees, attribution, qualification, handoff and cancellation in writing. See pricing, scenario calculator and named case studies with reporting limits.

2. CIENCE

Why second: the closest to Belkins in scale and breadth, with a full public price list.

CIENCE pricing lists $5,000 one-time GTM setup, $2,000 monthly strategic execution and $499 monthly platform access: $7,499 in month one and $2,499 recurring for those core components. Optional SDR capacity is separate; the page also lists $1,000 onboarding per SDR and meeting/commission economics. Confirm which charges apply to your scope. The core total is not an all-in SDR programme price.

3. Martal Group

Why third: the nearest match to the outsourced-sales-team scope, on the quote-only side.

Martal Group, headquartered in Oakville, Ontario, positions itself as an outsourced sales team rather than an email vendor, claiming 200+ onshore sales executives and 15 years in business (self-reported). Pricing is quote-only but the structure is published: per its pricing page, Tier 1A is a flat monthly fee after a 3-month pilot, and Tiers 2 and 3 add a sales commission after a 4-month pilot. Best for: B2B tech companies that want senior outsourced sellers and accept the pilot.

4. SalesHive

Why fourth: a Belkins-like channel mix, calling plus email, on month-to-month terms.

SalesHive's pricing page describes a flat fee with no setup fee, month-to-month terms and cancellation with written notice. Quotes vary by team model, channel mix and activity volume; both US-based and offshore SDR options are mentioned. Confirm included people, data and tools, notice requirements and the complete fee for your selected plan.

5. Sopro

Why fifth: the UK and European counterpart at comparable maturity.

Sopro, founded in 2015 and headquartered in Brighton, UK, with 300+ employees, runs fully managed, email-led multi-channel prospecting that stretches to display ads, phone and physical mail. Per its published pricing page, engagements start at around 3K GBP per month with explicitly no minimum contract. Best for: UK and European B2B companies from roughly 3K GBP per month.

6. Cleverly

Why sixth: the least like Belkins, but the lowest published entry price here.

Cleverly offers LinkedIn, cold email and cold calling services on its current website. Select the channel and service scope before comparing price. A current channel-by-channel price list was not established from the homepage reviewed for this entry; obtain the applicable package, setup, tools, minimums and cancellation terms in a written proposal.

7. SalesRoads

Why seventh: the US appointment-setting veteran that puts its starting price in writing.

SalesRoads runs US-based SDR appointment setting and lead qualification on four-week engagement cycles, continuing on a retainer basis. Its pricing page lists the floor outright: engagements start at $9,950 per four-week cycle, and a two-SDR program is listed at $16,750 per cycle (checked 17 August 2026). Best for: calling-led US appointment setting from a vendor that publishes where its pricing starts.

8. Callbox

Why eighth: the largest multi-channel machine on this list, sold as a team-plus-AI subscription.

Callbox is a full-service B2B lead generation and appointment-setting agency that pairs dedicated SDR teams with AI outreach across phone, email and LinkedIn. Its site describes the core model as subscription-based with custom pricing by campaign scope, and states plainly that it does not work on a pay-per-lead or commission basis; no figures are published. Best for: companies that want one vendor running coordinated outreach on every channel at once.

9. memoryBlue

Why ninth: the SDR-talent house, for teams that think of outsourcing as renting a bench.

memoryBlue recruits and trains B2B sales talent, then runs revenue programs from pipeline to close, with outsourced SDR and BDR teams concentrated in high-tech and public-sector accounts. It publishes no pricing; the site points to an ROI calculator and a strategy call instead. Best for: tech companies that want a managed SDR bench from a firm whose core trade is recruiting and training the reps themselves.

All of them, side by side

Belkins is the baseline row; "publishes pricing" means figures on the agency's own site.

How to choose between them

Decide the model before the vendor. If a fixed monthly program with a guaranteed appointment quota fits how you budget, Belkins is a credible incumbent and CIENCE is the transparent-pricing version of the same shape. If you want the agency's pay tied to what closes, that is our model: mechanics on the how revenue share works page, market dollar ranges on the agency cost guide, and the model-by-model risk breakdown on the pricing models comparison.

How this list was built and checked

These providers were selected to illustrate different service scopes and commercial models, not ranked by independently measured performance or buyer popularity. ReplyLead publishes the comparison and appears first. Provider claims are self-reported; dated source entries and the scoped pricing review should be distinguished from a complete current proposal.
