Best Cold Email Agencies in 2026: 11 Compared on Price, Contract and Channels

Most shortlists for "cold email agency" mix together three businesses that charge in completely different ways: agencies that run campaigns and hand you replies, appointment setters paid to fill your reps' calendars, and outsourced SDR firms that rent you people. We went through eleven of them, page by page, and recorded only what each company states on its own website. The thing that took the longest was finding prices, because most of them do not have any.

How we put this together

Every fact below comes from the company's own website, read on 3 September 2026. Where a website does not state something, the table says "Not stated" and the write-up says so. We did not copy founding years or client counts from directory listings, and we have not invented review counts or results for anyone. Numbers that vendors publish about themselves, like Belkins' "$2B+ in revenue" for clients or Callbox's 700+ staff, are marked as claims from their sites, because that is what they are.

We are Sales.co. We sell managed outbound, we appear at number two on this list, and we picked the order. You should discount that accordingly. The defence is that every entry can be checked against the vendor's own site in about two minutes, including ours, and we have listed our own limits in our section rather than leaving them out.

Two things surprised us while doing this. The first is how rare a published price is: nine of the eleven have no number anywhere a buyer would look. The second is Belkins. Its pricing page has four named plans and lists yearly appointment volumes for each, and not one dollar figure. Meanwhile a Belkins blog post comparing outsourced SDR companies gives Belkins' own price as $5,500 to $7,995 per month. The number exists. It is just not on the page called pricing.

The comparison table

The order runs roughly from "cold email is the core of what they sell" at the top to "cold email is one channel among several" at the bottom. That is the only ranking rule we used, and it means a vendor low on this list can still be the right one for you: memoryBlue and SalesRoads are serious companies, they just sell the phone first. Our outsourced SDR comparison ranks the same set the other way round.

1. Belkins

Belkins was founded in 2017 and is headquartered in Dover, Delaware, with offices in Colorado, Warsaw, and Kyiv and Lviv in Ukraine. The site put team size at 300 people as of the end of 2022 and does not give a current figure. It sells omnichannel appointment setting: cold email, cold and intent-based calling, voicemail, SMS and WhatsApp, LinkedIn outreach, paid ads, ABM, plus HubSpot consulting and deliverability work. It also built two products of its own, Folderly for deliverability and Charge for bulk sending through Outlook.

The pricing page lists four plans, Growth, Growth Plus, a small-business tier and Enterprise, and separates them by yearly appointment volume: 30+, 100+, 200+, or custom. There are no dollar figures on that page, and no stated contract minimum. As noted above, a Belkins blog post puts Belkins' own starting range at $5,500 to $7,995 per month, which is the most useful number available and is not where a buyer would look for it.

Belkins is a fit if you want a large vendor with a long track record and you are buying appointments rather than a channel. The limitation is the one every quoted-price vendor shares: you cannot compare it against anything until you have sat through a discovery call, and by then you have spent an hour.

2. Sales.co (that is us)

We publish this comparison, so treat this section as a claim sheet rather than a review. Everything here is on our pricing page and can be checked in a minute.

Sales.co runs the outbound function end to end: sourcing contacts, per-prospect research, writing and sending, managing deliverability, and answering replies. Two plans. Intent Takeover is $1,000/month for up to 1,000 high-intent leads a month with five or more touches each. TAM Takeover is $2,000/month for up to 20,000 ICP-matching leads a month with lighter personalization, covering your full addressable market every 30 to 90 days. Both together are $2,500/month. Cold calls are a $1,500/month add-on, LinkedIn and ads $1,000/month each. Month-to-month, no setup fee, no hourly billing, live in seven days. We have worked with 421+ clients over four years. Published case studies: Cytena at $700K in pipeline, Testimonial Hero at $85K, and Alts.co at 250+ leads.

The limits, since we are asking other vendors to state theirs. We do not publish a third-party review count. We are a much smaller operation than Callbox with its 700+ staff or memoryBlue with 600+ SDRs, and we do not run delivery in 15 languages across four continents, so a global multi-country campaign is not our strength. Cold calling is an add-on, not included in the base price, which makes us more expensive than the headline if the phone is central to your motion. What we do have that most of this list does not is a number on a public page, and at $1,000/month it is the lowest published starting price in the set.

3. SalesHive

SalesHive was founded in 2016 and has been remote-first since; the site does not state a headquarters. It books B2B meetings using what it describes as 100% US-based SDRs, with an offshore option, running on its own platform: a power dialer, an email personalization tool called eMod, a shared inbox and two-way CRM sync. Channels are phone only, or phone plus email.

Pricing is one flat monthly fee covering the SDR team, a strategist, the platform, data and tools, with no per-seat charges and no data add-ons. The figure is not published; you get a quote from a call. Terms are stated clearly: no setup fees, no long-term contracts, cancel any time with written notice, month-to-month available, annual plans priced lower. Volume tiers are described as 150+, 250+ or 500+ daily touches. Site claims include 129,000+ meetings booked and 2,285 clients.

Worth a shortlist if you want US callers and the ability to stop. The limitation for a cold-email-first buyer is the channel mix: email is sold as an addition to the phone, not the other way round.

4. Martal Group

Martal Group states 15 years in business without giving a founding year, and lists offices including Toronto and Ottawa, Berlin, Copenhagen and Guadalajara alongside US locations, without naming a headquarters. It states 200+ onshore sales executives. Services run from appointment setting and outbound lead generation through cold email, LinkedIn and cold calling to sales training and inbound lead qualification, and it markets an AI sales platform of its own.

The specialization is B2B technology: SaaS, software development, MSPs, cybersecurity, fintech, AI and machine learning, with healthcare, manufacturing and logistics also listed. If your buyer is a CTO, the argument for Martal is that their people have had that conversation before.

No pricing is published and no contract minimum is stated. The headcount claim, 200+ onshore executives, tells you what you are buying: capacity, priced by capacity, which usually means the quote scales with the number of people rather than with a defined scope of work.

5. Callbox

Callbox was founded in 2004 and is headquartered in Encino, California, with six offices across four continents including Australia, Singapore, Malaysia, Colombia and the Philippines, and 700+ full-time staff. It runs B2B lead generation, outsourced SDR, event marketing and inbound lead generation across voice, email, LinkedIn, chat, social, retargeting, content and webinars, and states coverage of 50+ countries in 15+ languages on its own platform, Pipeline.

The reason to shortlist Callbox is geography. If you need outbound into APAC or LATAM, or campaigns running in a language your team does not speak, very few vendors on this list can do it and Callbox states that it can. Industries listed include SaaS, healthcare, finance, cybersecurity, fintech, manufacturing and logistics.

No pricing and no contract terms are published. With 700+ staff and a 22-year history, the fair assumption is that Callbox quotes at the enterprise end and prices by programme rather than by month, but their site does not say, so ask.

6. CIENCE

CIENCE publishes the most detailed price card in this whole comparison, and it is worth reading before you talk to anyone else, because it gives you a sense of what the unpublished quotes are made of. The Core plan is a $5,000 one-time GTM system setup, plus $2,000/month for a strategic team, plus $499/month for the graph8 platform, which comes to $7,499 in month one. That covers four campaigns (intent-based, ICP-driven, website visitor targeting, competitor targeting) and 75,000 monthly platform credits.

SDR capacity is priced separately and openly, monthly, by seniority and region: Level 1 runs $1,500 offshore, $2,500 in Europe, $4,500 in the US; Level 2 is $2,500, $3,500 and $5,500; Level 3 is $3,500, $4,500 and $6,500. Onboarding is $1,000 one-time per SDR, and CIENCE states there is no long-term contract on SDR capacity. There are larger build packages on top, a $9,500 Programmable Revenue Blueprint and a $25,000 Standard Build, both over 60 days.

One structural note. CIENCE now sits inside the graph8 group alongside Tenbound, the research operation, with the group address given as Miami and a Boston office. Its about page describes CIENCE as a decade of managed outbound, inbound and SDR services. The founding year is not stated. If you are buying a long engagement, ask which entity you are actually contracting with.

7. Leadium

Leadium is headquartered in Las Vegas and does not state a founding year. The service list leads with data: lead research and data sourcing, deliverability and technology implementation, top-of-funnel consulting, then outbound appointment setting and inbound lead qualification. Channels include email, cold calling, LinkedIn, sales gifting and marketing events. Site claims include 500+ client companies and involvement in 76 client acquisitions and 5 IPOs.

Leadium is the pick when the thing breaking your outbound is the list rather than the sending. Plenty of teams have a competent sender and a bad ICP definition, and buying more sending capacity makes that worse rather than better. If you would rather own the data outright and run the sending yourself, our one-time verified email lists are $295 flat.

No pricing and no contract terms are published. The 67% cost-reduction-versus-in-house figure on their site is their own calculation, with no method shown, so treat it as marketing rather than a benchmark.

8. LevelUp Leads

LevelUp Leads is based in California with a fully remote team and does not state a founding year. It publishes a starting price of $5,000/month across three packages. Fractional SDR covers 150+ calls and 180+ emails per business day with 1,000 to 1,500+ contacts sourced monthly. Full-Service SDR is 300+ calls and 230+ emails a day with 1,500 to 2,000+ contacts. Growth is 700+ calls and 460+ emails a day with two full-service SDRs. All tiers include sales training, a reporting dashboard, their tech stack, a deliverability team and regular check-in calls.

Contract terms are stated, which is rarer than it should be: a three-month minimum, prepaid monthly, no onboarding charge, and 7 to 10 days to launch with billing starting after the first campaign goes live.

Publishing daily activity numbers next to a price is genuinely useful, because it lets you work out the cost per touch instead of guessing. The catch is the three-month prepaid commitment, which means the real entry cost is $15,000 rather than $5,000. Compare that against the month-to-month options before you sign.

9. memoryBlue

memoryBlue is headquartered in Tysons, Virginia, with offices in Austin, Dallas, Boston, Denver, London and Singapore. It states 20+ years in business without a founding year, and 600+ current SDRs, ISRs and AEs. Beyond outsourced sales development it runs demand generation, SEO and PPC, content, a sales training academy, and a recruiting arm that places sales talent from its alumni network. The stated specialty is public sector and technology organizations.

That recruiting arm is the thing that makes memoryBlue different from everyone else here. The pitch is that you can outsource sales development now and hire the people later, which is a real option if you know you eventually want the function in-house.

No pricing and no contract terms are published, and the site does not state which channels the SDR teams use, which is unusual. For a buyer whose question is specifically about cold email, that silence is a reason to ask early rather than a reason to rule them out.

10. SalesRoads

SalesRoads is headquartered in Boca Raton, Florida, and states 19 years of experience rather than a founding year. Services are appointment setting, lead generation, SDR outsourcing, outbound calling and email, list building, account reactivation and inbound appointment setting. It began by hiring military spouses into remote roles and still runs a remote workforce. Site claims include more than 500 companies served, 100,000 opportunities created, and three Inc. 5000 listings; it acquired VSA Prospecting in January 2025.

Contract terms are on the site in plain words: cancel anytime, no commitments. Only three vendors here say anything that direct.

No pricing is published. Belkins' blog cites roughly $9,950 per four-week cycle for SalesRoads, which is a competitor's number about a competitor, so we would not plan a budget on it. Email is listed as a channel but the operation is built around the phone, so if you want an email-led programme, this is not the obvious first call.

11. Cleverly

Cleverly is based in Los Angeles and does not state a founding year. It sells LinkedIn lead generation first, with cold email, cold calling, appointment setting and outsourced SDRs alongside. Published claims include 224.7K leads generated, $312M in pipeline, 1,000 active clients and 1,000+ five-star reviews. No pricing appeared on the pages we checked and no contract terms are stated.

LinkedIn-led outreach is a real strategy, particularly for smaller ICPs where you can afford to touch every account by hand and where connection requests still get accepted. Cleverly is the specialist for that on this list.

For a cold email buyer it sits last for a simple reason: email is the second thing they sell, not the first. If LinkedIn is your main channel, move them to the top of your own list.

Two more that did not fit the table

SalesBread is a boutique shop built around hand-researched outreach: a person reads each prospect and writes each message, rather than merging fields into a template. That works when you are selling into a few hundred named accounts and every message has to land. It does not reach a list of fifty thousand, and the small client roster means you may wait for a slot. No pricing is published on the site, and there is no cold calling.

ColdIQ sells a different thing again: it designs, builds and instruments the outbound stack, and your own sellers run it. That is useful if you plan to bring outbound in-house and want the infrastructure to belong to you from the start. It also means the result still depends on your team operating it every day, so there is no cost-per-meeting to compare against the vendors above. No pricing is published.

Neither appears in the table because neither publishes enough to compare on the same columns.

What cold email agencies actually cost

Two pricing models dominate. The first is a monthly retainer covering a defined scope. The second is a fee per booked meeting, usually with a setup charge on top. Buyers comparing vendors commonly report being quoted $500 to $1,000 per booked meeting. At twenty meetings a month, that is $10,000 to $20,000, which is why per-meeting pricing feels cheap in a proposal and expensive in a quarter.

The published starting points, gathered from the vendor sites themselves, look like this: Sales.co at $1,000/month; CIENCE at $2,499/month in recurring fees plus a $5,000 setup, so $7,499 in month one; LevelUp Leads at $5,000/month with a three-month minimum, so $15,000 committed; Belkins at $5,500 to $7,995/month per its own blog. Everything else is a quote. When a vendor will not publish a number, the number is almost always above the published ones, because publishing a low price is a sales advantage and nobody hides one.

Watch the setup fee, because it changes the comparison more than the monthly rate does. A $2,000/month retainer with a $5,000 setup costs more in the first six months than a $2,500/month retainer with none. Ask what the setup fee buys, and whether the domains and mailboxes it pays for belong to you afterwards.

The honest alternative: run it yourself

Every agency here competes with a tool stack. Instantly or Smartlead for sending and inbox rotation, Apollo for contact data, Clay for enrichment and research, and a few dozen warmed mailboxes. Between them, a few hundred dollars a month. If you have someone who can build a list, write copy that does not read like a template, watch deliverability daily and answer replies within the hour, the tools route costs a fraction of any retainer on this page and you keep the whole asset.

The catch is that the subscription is the smallest line in that budget. The list data, the sending infrastructure and above all the operator's hours are the real cost, and US SDR base salaries commonly run $50,000 to $65,000 before tools, management and ramp. The failure we see most often is a founder who buys the stack, runs it well for six weeks, gets busy, and finds three months later that replies went unanswered and two domains are burned. If the honest answer is that nobody owns this job full-time, the tools will not save you money. We wrote the long version in our tools versus managed service breakdown, and the reply-rate numbers either route should be judged against are in our cold email benchmark report.

Eight questions to ask on the call

These are the questions where answers diverge fastest between vendors that look identical on a website.

1. Who writes the copy, and do I approve it before it sends? Bad copy from your domain reaches exactly the accounts you care about most, and you only find out later.
2. Where does the contact data come from? One database means one set of gaps. Ask whether they enrich across multiple providers and what their verified-deliverable rate is.
3. Who owns the domains, mailboxes and data when I leave? If the answer is the agency, the warmed infrastructure walks out with them and you start from zero.
4. What happens after a positive reply, and how fast? Ask for the actual response time in minutes, and whether a human picks up the phone. A reply answered the next morning is often a dead reply.
5. Flat fee or per meeting? If per meeting, get the definition of a qualified meeting in writing, and the no-show policy.
6. What is the notice period? Three vendors here say cancel anytime on their websites. Most say nothing, and twelve-month terms turn up in quotes.
7. Who sits on my account, and where? Named people or a pool, onshore or offshore, dedicated or shared across five clients. It changes both the price and the output.
8. When does the first email send, and when is the first meeting expected? These are different dates, often weeks apart, and vendors quote the first one when you asked about the second.

Frequently asked questions

Which cold email agencies publish their pricing?

As of September 2026, four of the eleven put a number on a public page. Sales.co publishes $1,000/mo for Intent Takeover, $2,000/mo for TAM Takeover and $2,500/mo for both. CIENCE publishes a full price card: $5,000 GTM system setup, $2,000/mo strategic team, $499/mo for the graph8 platform, plus per-SDR monthly rates by region. LevelUp Leads publishes a starting price of $5,000/month. Belkins states $5,500 to $7,995 per month in one of its own blog posts, though its pricing page shows four plans with no figures. Callbox, Martal Group, SalesRoads, memoryBlue, Leadium and Cleverly quote on request.

How much does a cold email agency cost in 2026?

Buyers commonly report being quoted $500 to $1,000 per booked meeting, often with a setup fee on top, or a monthly retainer in the low to mid five figures once calling is included. The published starting points that exist range from $1,000 per month at Sales.co to $5,000 per month at LevelUp Leads, with CIENCE charging a $5,000 setup fee before the monthly line items begin. If a vendor will not give you a number before a discovery call, assume the number is above the published ones.

What is the difference between a cold email agency, an appointment setter and an outsourced SDR firm?

A cold email agency runs campaigns and hands you replies. An appointment setter is paid to put meetings on your reps' calendars, and usually adds phone follow-up because that is where meetings actually get booked. An outsourced SDR firm rents you sales development capacity, normally named people with a ramp period. Most of the vendors here sell more than one of the three, which is why comparing them on price alone produces nonsense.

Should I hire a cold email agency or run tools like Instantly or Smartlead myself?

The tools are cheap and good. Instantly, Smartlead, Apollo and Clay will cost a few hundred dollars a month between them. What they do not cover is the person who builds the lists, writes and rewrites the copy, watches deliverability, and answers replies the same day. A US SDR base salary commonly runs $50,000 to $65,000 before tools and management. If you already have that person and they have the hours, do it yourself. If you would be hiring for it, a managed cold email service is usually cheaper for the first year.

How long does it take a cold email agency to book the first meeting?

Domains and mailboxes need warming before volume sending, so almost nobody sends at scale in week one. Sales.co states clients are live in 7 days. LevelUp Leads states 7 to 10 days to launch. Most other vendors here do not publish a launch timeline. Ask for it in writing, and ask separately when the first meeting is expected, because launching a campaign and booking a meeting are weeks apart.

Who should own the sending domains, mailboxes and contact data?

You should, and you should ask before you sign. If the agency owns the domains, the warmed sending infrastructure leaves with them when the contract ends. If the agency owns the contact data, you pay again to rebuild the list. Sales.co gives clients full data export and CRM-ready records. Most vendors do not state a position on ownership publicly, so this is a question for the call.

Is per-meeting pricing safer than a flat monthly fee?

It moves risk to the vendor, which sounds good, and it also creates a reason to book meetings that no-show. If you buy per meeting, define in the contract what a qualified meeting is, who decides, and what happens when a prospect does not show up. Flat monthly pricing has the opposite failure mode: you carry the risk, so you need to see activity numbers weekly.

What contract length is normal for a cold email agency?

It varies more than price does. Sales.co, SalesHive and SalesRoads all state on their sites that you can cancel any time. LevelUp Leads states a three-month minimum with prepaid monthly billing. Belkins, Callbox, Martal Group, memoryBlue, Leadium and Cleverly do not state contract terms publicly. Twelve-month terms are common in quotes even when nothing on the website mentions them.

What reply rates should a cold email agency be able to produce?

Benchmarks move with industry, list quality and offer, and any agency quoting one guaranteed number is guessing. Ask for the range they see across their own book, and for the two worst accounts as well as the best. Our cold email benchmark report has the current distribution to check a quote against.

Where to start

Decide which of the three purchases you are making before you compare anyone: campaigns with replies handed back, meetings booked on your reps' calendars, or people rented by the month. Then shortlist inside that. For meetings, start with Belkins, Callbox and SalesRoads. For rented capacity, memoryBlue, CIENCE and SalesHive, and our outsourced SDR comparison goes deeper on that group. For a fixed scope at a known price, the four vendors that publish one are the only ones you can compare without a call.

If you want the version of this where you can check the price yourself, ours is on the pricing page: $1,000 a month to start, month-to-month, no setup fee. We also compare the field for appointment setting companies and B2B lead generation companies if those are closer to what you are buying.
