The 10 Best Outbound Agencies (2026)

Quick answer: the right outbound agency for your situation

• Your deals are worth $10K or more, you have reps who can take meetings, and you want the outbound program built around email to accounts showing a buying signal: IntentSignal, from $2,999 a month with no term.

• Your buyers answer the phone and you want US callers with a price you can read before the first call: SalesRoads, $11,950 for one SDR per 4-week cycle, cancel anytime.

• You want one retainer that covers email, LinkedIn, calling and events, with a yearly appointment target written into the plan: Belkins.

• You want the most dials per day for the money and can commit to a quarter: LevelUp Leads, from $5,000 a month.

• You want senior reps working email, LinkedIn and phone together after a structured pilot: Martal Group.

• You sell enterprise software or cybersecurity and want reps who are trained before they touch your account: memoryBlue.

• You want a multichannel team on month-to-month paper at the lowest entry budget: Leadium.

• You only want cold email, built in Clay, and you want to see a free test first: Growth Engine X.

• You want to add and drop outbound reps month by month: CIENCE. You sell across several countries or languages: Callbox.

If you already know email will carry most of your outbound, book a campaign plan call and we'll map the accounts and signals we would start with.

What counts as an outbound agency

An outbound agency runs prospecting for you: it picks the accounts, finds the people, writes the messages and books meetings onto your calendar. The channels are cold email, LinkedIn and the phone, in different mixes. Some firms are phone shops that added email. Some are email shops that never pick up a phone. A few sell a bundle of everything under one retainer.

That mix matters more than the logo list, because it decides what you pay for. A phone-led firm prices by the rep, since a person dialing is the cost. An email-led firm prices by the program, since software and copy do most of the work. Lead generation companies sit across both camps, and plenty of them sell lists or SDR hours rather than finished meetings. If you only want to rent SDR seats, our sibling ranking of outsourced SDR companies is built for that decision.

How we ranked them

We scored each firm on six things, all checked against the firm's own site or a review profile between October 29 and November 11, 2026:

• Pricing transparency. A dollar figure on the vendor's site beats a range quoted in a competitor's blog post.

• Minimum term. The real cost of finding out whether a firm works for you is what you owe before you are allowed to stop.

• Who owns the infrastructure. Domains, inboxes, phone numbers and lists you keep are worth something after you cancel. Most firms don't say.

• Channel fit. We looked at which channels each firm actually runs, per plan, and which one it leads with.

• Proof. Named case studies, plus review scores read alongside their counts (Clutch, G2, Trustpilot).

• Specialization. A team built for a type of buyer or deal size ranks above one that sells the same package to everyone.

A price marked "reported" comes from a third party and the vendor hasn't confirmed it. Several of those third parties sell competing services, which we note in the sources.

Outbound agencies side by side

The 10 best outbound agencies

1. IntentSignal: email-led outbound aimed at accounts with a reason to buy

We put ourselves first for one reason. In our experience running outbound for $10K+ B2B deals, most meetings start with a cold email, and the cheapest way to buy outbound meetings is to buy the channel that books them rather than a phone seat that also sends some email. IntentSignal is a B2B cold email agency for US companies with a sales team ready to take the meetings.

How it works: for each client we build AI agents in-house that study each target account, draft outreach tied to something that just changed there, and put meetings straight on your reps' calendars. We test fresh angles daily. Andrew Elsakr and Kyle Rasmussen, the co-founders, personally run every account, with no junior pod in the middle. We also run LinkedIn and paid ads, and calling through our outbound sales service, but email is the core.

Pricing: $2,999 a month to start, month to month. It's a retainer, and hybrid retainer-plus-performance deals are available. Our contract puts every sending domain and mailbox in your name, and they stay yours after you leave.

Proof: for Route, 117 opportunities in one month and $42M in ARR pipeline over three quarters. For Gainsight, 90 sales-accepted leads in two months, after 70 experimental campaigns over 11 weeks narrowed to 5 that we scaled. For Upside, meetings with leaders at 6.5% of all US restaurant locations in a single quarter.

Watch-outs: we are email-led, and we say so plainly. If your buyers live on the phone (field service owners, clinic managers, anyone who never checks a work inbox), hire SalesRoads (#2) or LevelUp Leads (#4) instead. The first weeks of any email program run below our benchmark of about 1 meeting per 100 emails on strong signals. We have no review-site score to quote, so judge us on the results above.

2. SalesRoads: the phone-led pick with a printed price

SalesRoads, in Boca Raton since 2007, is the firm to call if the phone is your main channel. Its reps dial and send personalized email; LinkedIn isn't part of the program. Each SDR gets 500 prospect records a month from a research team, and the firm sets up and warms "multiple domains and mailboxes" for the email side.

Pricing per 4-week cycle, from its pricing page: $11,950 for one SDR, $16,750 for two, $23,500 for three, $30,150 for four, $36,700 for five and $43,150 for six. There's no long-term commitment, though the page suggests a 12-week "go-to-market lab" before you judge results. Calling starts on business day 16 after kickoff.

Best for: companies selling to buyers who still answer desk phones, who want US callers and a rate card they can put in a budget today.

Watch-outs: the price is per seat, so you pay for the rep whether the dials connect or not. Following the suggested 12-week lab with one SDR costs $35,850. Ownership of the domains it sets up isn't stated. Reviewers on Clutch raise reporting clarity and SDR turnover. Proof: Clutch 4.9 from 69 reviews, G2 4.9 from 13; Microsoft and Paylocity appear on its about page. Our SalesRoads alternatives page compares it with other phone-first firms.

3. Belkins: one retainer, channels unlocked by plan

Belkins, founded in 2017, sells outbound as tiered retainers, and its pricing page shows exactly which channels each tier includes. Small Business (30+ appointments a year, run through partner agencies) gets cold email and LinkedIn only. Growth (100+ a year) adds intent-based calling, WhatsApp, executive dinners and conference activation. Growth Plus (200+ a year) adds general cold calling, ABM, paid ads and webinar support.

Pricing: no dollar figures on the page. Salesforge, which sells a competing product, reports $5,000 to $14,800+ a month, a $2,000 to $5,000 setup fee and 3 to 6 month minimums. It also cites a Clutch-reported figure of about $5,500 a month for 10+ meetings.

Best for: a buyer who would rather sign one contract for inbox, LinkedIn and dialer, and wants a yearly appointment floor on paper.

Watch-outs: the appointment counts are yearly floors, and "qualified" isn't defined publicly. Plain cold calling only arrives on Growth Plus. Salesforge reports launch in 4 to 6 weeks and results in 60 to 90 days. Proof: Clutch 4.9 from 234 reviews and G2 4.7 from 95, the deepest review record here. See our Belkins pricing breakdown for scenarios.

4. LevelUp Leads: the most calls per dollar

LevelUp Leads, founded in 2021 per Clutch with a remote team based in California, publishes daily activity floors instead of prices. Its packages page lists the Fractional SDR at 150+ calls and 180+ emails a day, the Full-Service SDR at 300+ calls and 230+ emails, and Growth (two SDRs) at 700+ calls and 460+ emails. Each omni-channel tier also runs one or two LinkedIn profiles.

Pricing: "starting at $5,000" a month, quoted per client, prepaid monthly. There's an initial 3-month commitment, then month to month. Onboarding is free and billing begins at the first launch, typically 7 to 10 days after the onboarding call.

Best for: buyers who think in dials and want a phone-heavy program with email and LinkedIn alongside, at a lower monthly figure than a US seat at SalesRoads.

Watch-outs: three prepaid months at the entry price is $15,000 committed up front. Clutch reviewers asked for dial-level reporting and mention coaching SDRs on messaging more than once. Domain ownership isn't stated. Proof: Clutch 5.0 from 61 reviews; case studies on Vodafone, CallTower and Corevest.

5. Martal Group: senior reps across three channels, after a pilot

Martal Group, founded in 2009 and based in Oakville, Canada, assigns senior SDRs who work cold email, LinkedIn and calling together. Each rep sends from a custom domain, according to Salesforge. An inbound tier adds SMS, SEO and LinkedIn ads.

Pricing: not public. Martal's tiers carry a flat monthly fee, and Tiers 2 and 3 add a sales commission whose rate isn't disclosed. Third parties report $4,500 to $6,195+ a month for the outbound tier (Belkins) and $5,000 to $9,000 typical (LeadHaste); both are competitors. Tier 1A starts with a 3-month pilot, Tiers 2 and 3 with 4 months, then monthly.

Best for: mid-market tech sellers who want one experienced rep running every channel, and who can budget a 3 to 4 month test.

Watch-outs: the pilot is the real minimum, roughly $13,500 to $36,000 at reported prices. Clutch reviewers note a 2 to 3 week calibration period and some meetings outside the ICP. Who keeps the custom domains when you stop isn't stated. Proof: Clutch 4.8 from 109 reviews (cost scored lowest, at 4.6) and G2 4.6 from 135. Details are on our Martal pricing page.

6. memoryBlue: phone and email reps for enterprise tech

memoryBlue, now merged with London-based Operatix, has been in business for 20+ years and serves B2B tech and professional services, with cybersecurity, data, fintech and GovTech called out on its site. Every rep clears a 12-step hiring process, then six weeks in its Academy, before working a client account. It also runs B2G lead generation and recruits SDRs for clients.

Pricing: not public beyond a cost calculator. Clutch shows a $5,000+ minimum project. Competitors report $7,000 to $12,000 per SDR a month with a 6-month minimum (Modern Inbound, CIENCE), and Belkins says from $11,000 a month with a 6-month pilot paid upfront.

Best for: enterprise software and security vendors whose buyers expect a polished caller, and who plan to keep outbound running for a year or more.

Watch-outs: Belkins expects 2 to 5 appointments in month 1, rising to 10 to 12 a month from month 4. That puts steady-state cost at roughly $583 to $1,200 per meeting at reported prices. Clutch reviewers mention rep turnover slowing delivery. Proof: G2 4.6 from 297 reviews, Clutch 4.7 from 23; Adobe, CrowdStrike and Palo Alto Networks appear among its site logos.

7. Leadium: multichannel on month-to-month paper

Leadium, based in Las Vegas, runs outbound email, cold calling, LinkedIn prospecting and sales gifting. Its pricing page lists no prices. The quote form starts its budget menu at $2,500 to $3,500 a month, and the FAQ promises month-to-month contracts for everyone. Onboarding happens only on the 1st or 15th of a month, and appointment setting goes live 7 to 10 days later.

Best for: smaller B2B teams that want to try phone, email and LinkedIn together without a pilot commitment.

Watch-outs: Leadium guarantees activity, not appointments. It caps how many new clients it takes each month, so a slot may not be open when you want it. Domain ownership isn't addressed. Proof: Clutch 5.0 from 90 reviews; we found no G2 profile.

8. Growth Engine X: cold email only, and you keep the build

Growth Engine X, now at coldoutbound.com and founded by former Clay employee Eric Nowoslawski, runs cold email and nothing else; LinkedIn appears on its site only as a data source. It sets up about 50% more sending capacity than the target volume, using backup domains, and states that domains, inboxes, Clay tables and lists all transfer to you.

Pricing: not published. Qualifying businesses can apply for a free test campaign, judged on positive responses. Ramp per its site: weeks 1 and 2 for onboarding and warmup, first campaigns in weeks 3 and 4, scaling in month 2.

Best for: US B2B companies with $1M+ revenue and a market of 100,000+ contacts that want email at volume. It says markets under 40,000 contacts are usually a poor fit.

Watch-outs: the free test is only offered to companies without a matching case study or with no outbound history. Paid contract terms aren't published. Proof: case studies including Clay, Notion and Snitcher on its own site; we found no Clutch, G2 or Trustpilot profile.

9. CIENCE: build the team line by line

CIENCE has been the services arm of graph8 since 2025, and its pricing page prices each piece separately: a $2,000 monthly campaign team, the graph8 platform at $499 a month with 75,000 credits, and SDRs from $1,750 a month offshore or $3,500 in the US or Europe. Reps work email, phone and LinkedIn.

Pricing math: one offshore SDR comes to $4,249 a month before the one-time setup fee (amount not listed) and a bonus that starts once an SDR passes 60% of a held-meeting target. No term applies, and CIENCE says programs go live in under 14 days.

Best for: a product launch or a seasonal push where you want three reps for a quarter and one after.

Watch-outs: the review record is the weakest in this top ten. Clutch reviewers describe months with no meetings, staff turnover and trouble exiting. Proof: Clutch 4.2 from 142 reviews, G2 3.7 from 181.

10. Callbox: outbound pods for many countries at once

Callbox, founded in 2004 with HQ in Encino, California and offices in Singapore, Australia, Colombia and London, runs "Campaign Pods" that combine SDRs, data and a campaign manager across phone, email, LinkedIn, chat, webinars and SMS. Per its pricing FAQ, a typical program runs $20,000 to $40,000 a quarter, with the figure set by staffing, the number of languages, target regions and data complexity.

Best for: companies selling into several regions or languages, especially in APAC, that want one firm covering all of them.

Watch-outs: the FAQ doesn't state a minimum or contract length; third parties report 3 to 12 months, with 12 common. Clutch reviewers flag weaker results outside English-speaking markets and shallow reporting. Proof: Clutch 4.6 from 128 reviews, G2 4.5 from 91.

How to choose an outbound agency

Start with the channel that books your meetings

Look at your last 20 closed deals and ask how the first conversation started. If buyers took a cold call, a phone-led firm earns its seat price. If the first reply came from an email or a LinkedIn message, paying for a full-time caller means paying for activity your market ignores. Our cold email statistics show one reason email-led programs can stay lean: 82% of the positive replies we see come from the first email in a sequence, so most of the cost sits in targeting and copy rather than in long follow-up chains.

Ask who owns what you paid to build

Only two firms on this list put ownership in public: IntentSignal (domains and mailboxes, in writing) and Growth Engine X (domains, inboxes, Clay tables and lists). SalesRoads, CIENCE and Martal all build sending infrastructure as part of setup but don't say who keeps it. That matters on day one of your next agency, because warmed domains take weeks to replace.

Year-one cost at sourced prices

Cost per meeting, where the numbers exist

Few firms publish meeting counts next to prices, so this is the short list. The Clutch-reported Belkins figure of $5,500 a month for 10+ meetings works out to $550 per meeting or less. A Belkins Growth plan priced between $60,000 and $177,600 a year that delivers its 100-appointment floor lands at $600 to $1,776 per appointment. memoryBlue at steady state, 10 to 12 meetings a month on $7,000 to $12,000, runs about $583 to $1,200.

For an email-led program the useful number is break-even. At $2,999 a month, IntentSignal matches a $550 meeting at about 6 meetings a month and a $1,200 meeting at about 3. At our benchmark of roughly 1 booked meeting per 100 emails on strong account signals, 6 meetings takes around 600 well-aimed emails; with generic targeting, closer to 1 in 200, it takes about 1,200. Ramp-up months come in under those rates. Our cold email agency pricing guide has more scenarios.

Run a pilot you can actually afford to lose

What you owe before you're allowed to stop is the real price of a test. Here is that number per firm, at sourced or reported prices:

Set the pilot's pass mark before it starts: a number of held meetings with accounts in your ICP, measured at a fixed date. Give email programs a month to warm up and phone programs a few weeks for list building and scripts. If a firm won't agree to a written definition of a meeting before you sign, take that as your answer.

Questions to ask before you sign

• Which channel books most of your meetings for clients like us, and can you show the split?

• Who owns the domains, mailboxes, phone numbers, lists and copy when the contract ends, and where is that written?

• What exactly is a billable meeting: booked, held, or held with someone in our ICP?

• What do we owe if we stop after the first month, including setup and prepaid fees?

• Who writes the messaging and who runs the account day to day, and how long have they been there?

• When does sending or calling start, and what results should we expect in month one versus month three?

Where IntentSignal fits

IntentSignal is the outbound agency for US B2B companies with $10K+ contract values whose meetings start in the inbox. Every email is written around something happening at that account, and a founder is on every account. You own the sending infrastructure and can stop in any month. If your best deals start with a phone call, use SalesRoads or LevelUp Leads; we would rather send you there than sell you the wrong channel. Want to see how we rank against email-only firms?

Frequently asked questions

What does an outbound agency do?

It runs prospecting for you: building account lists, finding contacts, writing and sending messages by email, LinkedIn or phone, handling replies and booking meetings for your sales team. The main differences between firms are which channel they lead with and whether they bill per rep or per program.

How much does an outbound sales agency cost?

On sourced prices in this ranking, from about $2,500 a month (Leadium's lowest budget band) and $2,999 a month (IntentSignal) up to $11,950 per 4 weeks for one US phone SDR at SalesRoads. Year one ranges from about $30,000 to $155,000 or more for a single program or seat.

Are outbound lead generation companies the same as outbound agencies?

Often not. Many lead generation companies sell contact lists or SDR hours, and you do the selling. An outbound agency is judged on booked meetings. Ask any firm whether it bills for leads, activity or held meetings before you compare prices.

Does email or phone book more outbound meetings?

It depends on your buyers. For $10K+ B2B deals with buyers who work from an inbox, most of the meetings we see start with a cold email. For buyers who rarely read work email but answer the phone, a phone-led firm such as SalesRoads or LevelUp Leads is the better buy.

Who owns the domains and mailboxes an outbound agency sets up?

It varies and most firms don't say. IntentSignal gives clients ownership of every domain and mailbox in writing. Growth Engine X says domains, inboxes, Clay tables and lists transfer to you. SalesRoads, CIENCE and Martal build infrastructure in setup without stating ownership publicly, so get it in the contract.

How long until an outbound agency books the first meetings?

Published timelines run from 7 to 10 days to launch (LevelUp Leads, Leadium) to calling on business day 16 (SalesRoads). Email programs need about two weeks of warmup first; Growth Engine X starts campaigns in weeks 3 and 4. Belkins results take 60 to 90 days, per a third-party review.

Should I hire an outbound agency or rent SDR seats?

If what you want is meetings, compare programs on cost per meeting. If you want a dedicated rep you manage like an employee, compare seat prices instead. Our ranking of outsourced SDR companies covers the seat option.
