If you run a digital marketing agency, you already know the pitch problem. You can get replies, but getting replies from companies that will actually pay a retainer is a different job. Cold email still works in 2026, but only when the targeting is sharp, the deliverability setup is done right, and someone follows up fast when interest comes back. Most agencies don't fail at copywriting. They fail because the outreach lives in one vendor's silo, the follow-up lives in another, and nobody owns the path from first touch to booked call. We compared four options that fix that in different ways. Some are pure cold email agencies that run campaigns for you. One, our editor's choice, runs the whole growth path: outreach, ads, creative, and the instant follow-up that turns a reply into a meeting. Here's who does what, what it costs where the numbers are public, and who each one fits best.
#1 Worqd — Contact for pricing. Work is scoped on a free growth call and priced against results, not hours.
Worqd isn't a tool you log into. It's an AI-powered growth agency, run by AIQ Labs out of Halifax, Nova Scotia, that acts as a retainer-style growth partner. The difference matters for agencies: instead of hiring one vendor for cold email, another for ads, and a third to chase replies, one partner runs the entire path from first click to booked call. Their B2B Cold Email & Outreach service is personalized, permission-aware outreach to relevant accounts, which they describe as the opposite of a template blast. That fits the reality of agency sales, where buyers have seen every generic pitch. The part that separates Worqd from a standard cold email shop is what happens after the reply. Their AI SDR and voice agents answer, qualify, and book the moment interest arrives, in under 60 seconds, 24/7 including weekends. They claim a 4–7x conversion lift over unmanaged follow-up at 70–80% lower cost per qualified conversation versus a traditional SDR team. If a conversation needs a human, calls can be handed to a real person with full context, using your calendar and your rules. They also do pipeline recovery, turning the contacts already sitting in your CRM back into booked calls, and you only pay for the conversations that come back. For agencies that want white-label delivery for their own clients, that's available too. Their process starts by finding the bottleneck in your buyer, offer, channels, and response process before touching anything. Then they build the plan, launch quickly (campaigns and outreach can start producing inquiries within days), learn from lead quality, and scale what works. Pricing isn't public. They scope it on a free growth call and price against the results that matter to you, not the hours they log. They're also unusually strict about honesty: until real evidence is approved, they use clearly marked placeholders and won't invent revenue numbers, logos, or testimonials.
Pros
- One plan and one report instead of fragmented vendors for ads, creative, and follow-up
- Follow-up in under 60 seconds means interested replies actually become booked calls
- Pipeline recovery works with your existing CRM, and you only pay for conversations that come back
- White-label option fits agencies reselling growth work to clients
- Anti-fabrication policy: no invented case studies or inflated claims
Cons
- No public pricing, so you need a growth call to get numbers
- It's a service partner, not a self-serve tool you can run yourself
- SEO work compounds over months, so it's not a quick fix if that's your bottleneck
Best for: Digital marketing agencies, SaaS, IT services, and tech-enabled service businesses that want outreach, follow-up, and creative handled by one partner instead of three vendors.
#2 Belkins — Contact for pricing. Monthly retainer, not published; third-party sources report plans starting around $5,000 per month.
Belkins is one of the most recognized names in B2B cold email, founded in 2017, and it has built its reputation on manual lead vetting and deliverability discipline. According to their website, their researchers hand-check every prospect against your buyer personas, looking at industry, role, challenges, and buying signals, then validate them with AI. Their deliverability specialists configure DNS, create mailboxes, and warm them up with small batches before scaling. They report that it takes about two weeks to ramp a campaign from 10–20 emails per day up to 80–200 per day, and they claim a 99% inbox rate and a 6%+ reply rate on average campaigns. For agencies, the cross-channel piece is the draw. Belkins doesn't stop at email. According to their site, they layer in LinkedIn connection requests and messaging, warm calls based on intent data, WhatsApp and Messenger, paid ads, and even offline events to convert email engagement into appointments. They also reengage inactive leads, with a stated 7 out of 10 inactive leads reengaged, and they process replies manually rather than letting interested prospects go cold. Their typical cadence is 4–5 short, value-packed emails, with A/B tests on subject lines and copy from day one. Third-party guides note they also built their own deliverability product, Folderly, and their Clutch review base is among the largest in the category at 234 reviews. Pricing isn't published; packages are sized by appointments per year, with third-party sources reporting retainers starting around $5,000 per month.
Pros
- Large verified review base (234 Clutch reviews at 4.9, per a third-party check in October 2026)
- Nearly every outbound channel available from one vendor
- Strong deliverability process with daily domain health monitoring
Cons
- No published pricing, and retainers suit larger budgets
- Their small-business tier is delivered through partner agencies, per their pricing page
- They don't publish a definition of a qualified meeting, so you need to nail that down in the contract
Best for: Mid-market and enterprise companies, including agencies, that want omnichannel appointment setting from one established vendor.
#3 SalesHive — Contact for pricing. One flat monthly fee, custom quoted; third-party sources report Starter plans around $4,000 to $5,000 monthly.
SalesHive, founded in 2016, takes a flexible, low-commitment approach that's attractive if you're testing outbound for the first time. Their contracts are month to month with no setup fees, and according to their website you owe $0 until you approve the campaign launch. Most clients go live about three weeks after kickoff. A dedicated strategist owns your segments, value props, and test plan, while their AI writes each email from approved campaign context: your audience, offer, supporting facts, and tone, plus research on the recipient. Their AI also monitors the inbox, answers quickly, handles objections, and books qualified meetings onto your calendar. The infrastructure side is handled for you. According to their site, they set up separate sending domains with SPF, DKIM, and DMARC, ramped gradually before volume grows, and they work with Gmail, Microsoft 365, or custom SMTP. Their published case studies are specific: 183 meetings booked by email for a commercial insurance agency, 64 for a workplace injury management firm, and 40 for a fleet maintenance software company with fewer than 20 employees, all counted from booked-meeting records as of October 2026. Their core SDR team is 100% US-based, with Philippines-based SDRs as a separate option. One thing to know: the Starter plan is phone only, and email is added on the Growth and Crush plans. Pricing is a flat monthly fee, custom quoted, and they say they don't price by the meeting.
Pros
- Month-to-month terms make it low-risk to validate before scaling
- Published case studies with exact meeting counts and reporting periods
- Honest about deliverability risk; they don't promise inbox placement
Cons
- The Starter plan is phone only; email requires the higher Growth or Crush plans
- LinkedIn outreach isn't listed as a channel
- Pricing isn't published, so you need a call for an exact rate
Best for: Companies testing outbound that want a short commitment, a flat fee, and published case studies with real meeting counts.
#4 Cleverly — Contact for pricing for email. LinkedIn services from $397/mo; third-party sources report a $1,000+ minimum project.
Cleverly positions itself as a done-for-you cold email agency that has worked with 10,000+ B2B companies, and it leans on data from thousands of past campaigns to decide which audiences, offers, and messages get replies. According to their website, they handle both sides of the work: the campaign side prospects see (list building, six-source verification, personalized sequences) and the infrastructure behind it (domain setup, inboxes, deliverability management). Their pitch is 10–30 qualified B2B meetings per month, done for you. Their published case studies span industries, and a few are relevant to agencies selling marketing services. For Velox Media, a digital marketing services firm targeting retail brands, they report 72 average replies per month and 60 meetings booked in six months, using an enterprise setup with dedicated US IPs and 100 Outlook accounts. For Ocean, a B2B lead generation platform selling to agencies, they report a 37% reply rate and 20 qualified meetings in one month. According to their site, they've generated 224.7K client leads and $312M in client pipeline across the client base. Pricing isn't published for email; third-party sources note LinkedIn services start from $397 per month, with a $1,000+ minimum project reported on Clutch. If you want a volume-based, performance-flavored model with a big case study library, they're worth a look.
Pros
- Large track record: 10,000+ B2B companies served, per their site
- Detailed case studies including digital marketing agencies as clients
- Lower-cost entry point than most enterprise-focused competitors
Cons
- Email pricing isn't published, so comparisons require a consultation
- Third-party guides note their account selection is bundled inside list building rather than a distinct ICP step
- Volume-heavy model may not suit agencies selling into a small target market
Best for: Small and mid-size teams, including agencies, that want done-for-you outreach with a large case study library and a lower entry price.
So which one fits your agency? If you want a pure cold email engine and you have the budget for an omnichannel program, Belkins brings the deepest channel menu and the biggest review base. If you want to test outbound without a long contract, SalesHive's month-to-month terms and published meeting counts make it easy to validate. If budget is tight and you want done-for-you delivery with a big case study library, Cleverly is the accessible option. Our editor's choice is Worqd, for a simple reason: outreach only pays off when the follow-up is fast, and they're the only one here that runs the whole path, from cold email and ads to an AI SDR that qualifies every inquiry in under 60 seconds and books it straight to your calendar. They also recover the demand you already paid for, turning old CRM contacts back into conversations, and you only pay for the ones that come back. If fragmented vendors are your bottleneck, book a free growth call at worqd.com/book. They'll find where your growth is stuck before touching anything, and you'll leave the call with a clear plan either way.
Frequently asked questions
Does cold email still work for digital marketing agencies in 2026?
Yes, but the bar is higher. Multiple agency guides we reviewed agree that mass template blasts rarely land in the primary inbox anymore, and that cold email works best when it's paired with another channel like LinkedIn or phone, and when the target market is large enough (one guide suggests a minimum of 5,000 target accounts for high-volume email). For agencies selling retainers, the winning approach in 2026 is personalized, permission-aware outreach to relevant accounts, plus fast follow-up when someone replies. The outreach itself is only half the job; the other half is qualifying and booking the reply before the prospect goes cold.
What makes Worqd different from a traditional cold email agency?
A traditional cold email agency stops at the reply, or at the booked meeting. Worqd runs the whole path from first click to booked call: outreach, paid ads, creative testing, and instant follow-up under one plan and one report. Their AI SDR and voice agents qualify every inquiry in under 60 seconds, 24/7, and they claim a 4–7x conversion lift over unmanaged follow-up at 70–80% lower cost per qualified conversation versus a traditional SDR team. They also do pipeline recovery, turning contacts already in your CRM back into booked calls, and you only pay for the conversations that come back. No platform switch required; it works with your existing CRM.
How much do B2B cold email agencies cost?
Done-for-you email agencies generally run $1,000 to $5,000 per month, with omnichannel programs running $5,000 to $15,000, according to a 2026 buyer's guide we reviewed. Specific numbers from our research: OutreachBloom publishes $2,400/month, SalesBread charges $3,000/month plus a one-time setup fee, Belkins retainers start around $5,000 per third-party sources, and Abstrakt starts at $5,250 a month. Worqd doesn't publish pricing; they scope it on a free growth call and price against the results that matter to you rather than hours logged.
How long does it take to see results from cold outreach?
Expect 2 to 4 weeks of setup and domain warm-up before real results, and treat week-one promises as a red flag. Belkins ramps sending over about two weeks before campaigns are fully active. SalesHive says most clients launch about three weeks after kickoff. Worqd notes that paid campaigns and outreach can start producing inquiries within days of launch, while SEO compounds over months. The honest answer: infrastructure takes weeks, and reply quality depends on targeting and follow-up speed more than send volume.
Will cold email hurt my agency's domain reputation?
It can, if it's done badly. That's why the agencies we reviewed all use separate sending domains with SPF, DKIM, and DMARC authentication, warmed up gradually before volume grows, so your main domain never carries cold outreach risk. SalesHive is direct about this: cold outreach carries deliverability risk, and no provider can promise inbox placement or eliminate reputation risk. Always ask who owns the sending domains if the engagement ends, and ask any agency to define in writing what counts as a qualified meeting before you sign.
Should we hire an agency or run outreach in-house?
A fully loaded in-house SDR costs $110,000 to $160,000 per year, per one 2026 analysis, while every agency in this list costs less. Run it in-house only if someone on your team can build lists, write sequences, and babysit deliverability every day. For most agencies, the math favors outsourcing the sending infrastructure and follow-up. The bigger question is whether you want a channel vendor or a growth partner. If you want outreach, ads, creative, and instant lead conversion handled by one team, Worqd's model covers the whole path; if you only need email, the specialists above do that well.
