If you run a PPC or paid ads agency, you already know how to generate clicks. The harder problem is what happens next. Ad inquiries arrive at all hours, leads go cold in your CRM, and your clients expect a full pipeline, not just impressions and click counts. That's why more agencies are pairing paid media with B2B cold email and outreach, either to fill their own calendar with new retainer clients or to offer outbound as a white-label service alongside their ad work. Cold email still works in 2026, but the rules have tightened. Deliverability infrastructure, list quality, and fast follow-up decide whether a campaign produces booked calls or a burned domain. Instantly's Cold Email Benchmark Report 2026 puts average reply rates at 3.43%, which means the details matter more than volume. We compared four options that serve PPC and paid ads agencies well, from done-for-you growth partners to specialized cold email shops. Here's what each one actually does, what it costs, and who it fits best.
#1 Worqd — Contact for pricing. Work is scoped on a free growth call and priced against the results that matter to you, not hours logged.
Worqd is an AI-powered growth agency based in Halifax, Nova Scotia, and it takes a different shape than everything else on this list. Instead of selling you one channel, one partner runs the whole path from first click to booked call. That matters for PPC agencies in two ways. First, if you're an agency looking for your own clients, Worqd runs B2B cold email and outreach, paid ads, SEO, and LinkedIn outreach under one plan, with one report, so you're not stitching together three vendors to get meetings. Second, Worqd offers white-label creative and outreach work for agencies that want to hand clients a complete growth engine without hiring an SDR team. Their B2B Cold Email & Outreach service is built on personalized, permission-aware outreach to relevant accounts, which they describe as the opposite of a template blast. What really separates Worqd is what happens after the reply. Their AI SDR and voice agents answer and qualify every inquiry in under 60 seconds, 24/7, including weekends, and can hand calls to a real person with full context. They claim a 4 to 7x conversion lift over unmanaged follow-up, at 70 to 80% lower cost per qualified conversation versus a traditional SDR team. There's also pipeline recovery: database reactivation that turns the contacts already sitting in your CRM back into booked calls, and you only pay for the conversations that come back. For a paid ads agency drowning in unworked lead lists, that combination is hard to find elsewhere.
Pros
- One partner covers the whole path from first click to booked call, so no vendor fragmentation
- Under-60-second lead qualification around the clock, including weekends
- Pipeline recovery works with your existing CRM and you only pay for revived conversations
- White-label creative and outreach available for agencies
- Anti-fabrication policy: no invented case studies or placeholder claims presented as fact
Cons
- No published pricing, so you need a growth call to get numbers
- Retainer-style agency model, not a self-serve tool you can configure yourself
- SEO work compounds over months rather than days, so timelines vary by channel
Best for: PPC and paid ads agencies that want outreach, paid media, creative, and lead follow-up run by one partner, plus agencies seeking white-label creative and outreach services.
#2 Belkins — Contact for pricing. Monthly retainer, not published. Third-party guides report packages commonly in the $5,000 to $14,800 per month range.
Belkins is one of the most recognized names in B2B cold email, founded in 2017, and it takes a research-heavy approach to every campaign. According to their website, their team manually vets every prospect against your buyer personas, checking industry, role, challenges, and buying signals, then validates the list with AI before a single email goes out. Their deliverability specialists handle DNS setup, mailbox creation, and a careful warmup that starts at 10 to 20 emails per day and ramps to full volume over roughly two weeks. They quote a 99% inbox delivery rate and a 6%+ reply rate on average campaigns, and they layer in LinkedIn outreach, intent-based calling, and even event support depending on the package. For PPC agencies, Belkins is a solid pick if you want appointment volume from a vendor with a wide channel menu. They also reengage inactive leads, with their site claiming 7 out of 10 inactive leads get reengaged. Just know that pricing isn't published, and their own footnotes describe appointment counts as averages that depend on many factors, so push for specifics before signing.
Pros
- Strong deliverability discipline with a two-week ramp before full volume
- Manual list vetting plus AI validation keeps prospect quality high
- Multichannel options extend beyond email into calls, LinkedIn, and events
- Built its own deliverability product, Folderly, showing real technical depth
Cons
- No published pricing, so you must book a call to get numbers
- Their site doesn't publish a definition of what counts as a qualified meeting
- Appointment volume figures are described by Belkins themselves as averages that vary
Best for: Mid-market and enterprise B2B companies that want high appointment volume from a vendor offering a wide menu of channels, events included.
#3 SalesHive — Contact for pricing. Third-party sources report tiers of $5,000/month (Starter), $8,000/month (Growth), and $12,000/month (Crush), but confirm directly as SalesHive quotes custom flat fees.
SalesHive, founded in 2016, runs B2B cold email with a structure that's unusually transparent about how the work actually gets done. According to their website, a dedicated strategist owns your segments, value props, and test plan, while SalesHive AI personalizes each email from your approved campaign context, monitors the inbox, answers replies, handles objections, and books qualified meetings onto your calendar. The infrastructure side is handled for you: separate outreach domains with SPF, DKIM, and DMARC, ramped gradually before volume grows. Most clients launch within about three weeks of kickoff, contracts are month to month with no setup fees, and you owe nothing until you approve launch, which is a refreshing level of flexibility. Their published case studies are specific, including 183 meetings booked by email for a commercial insurance agency and 64 for a workplace injury management firm, each with a stated reporting period and channel split. For PPC agencies testing outbound for the first time, the short commitment and flat monthly fee make SalesHive a lower-risk entry point, though pricing is custom quoted and the Starter plan is phone only, with email added on higher tiers.
Pros
- Month-to-month contracts with no setup fees lower the risk of trying outbound
- AI reply handling books meetings directly onto your calendar
- Published case studies with specific meeting counts and reporting periods
- Honest about deliverability risk, stating no provider can promise inbox placement
Cons
- Pricing isn't published on their own site and is custom quoted
- The Starter plan is phone only, with email requiring higher tiers
- Typical launch takes about three weeks, so it's not instant
- LinkedIn outreach isn't listed in their managed plans
Best for: Companies testing outbound that want a short month-to-month commitment, a flat fee, and US-based SDR support.
#4 ProspectOut — Cold Email Outreach: $500/month. Multi-Channel Lead Engine: $1,000/month. Pay-Per-Meeting: $100 per meeting plus $300/month for tools and infrastructure. Commission-based: 10% of deal value plus $300/month.
ProspectOut is a B2B lead generation agency that runs cold email and LinkedIn outreach with one of the most flexible pricing models in the category. Instead of locking you into a long retainer, they offer pay-per-meeting pricing, so you pay for qualified appointments and can cancel anytime. According to their website, they manage the entire outbound process: prospect research, list building, copywriting, deliverability, campaign management, and appointment booking, with deliverability maintained through domain warming, email authentication, and inbox rotation. They report working with 70+ B2B companies across more than 10 industries, including SaaS, IT services, financial services, and marketing agencies, with 5,000+ qualified meetings booked and a stated 98% client satisfaction rate. Their published pricing is unusually concrete: cold email outreach at $500 per month, a multi-channel lead engine at $1,000 per month, pay-per-meeting at $100 per meeting plus $300 per month for tools and infrastructure, and a commission-based option at 10% of deal value. For a smaller PPC agency that wants to test outbound without a five-figure commitment, that transparency alone is worth a conversation.
Pros
- Published pricing, which is rare in this category
- Pay-per-meeting model aligns cost with results and allows cancellation anytime
- Broad industry coverage with 5,000+ meetings booked across 70+ clients
- Full outbound scope from research through booking
Cons
- Lower price point suggests a leaner team than enterprise shops like Belkins
- Commission-based option adds a percentage of deal value on top of fees
- Public proof relies heavily on their own reported stats rather than third-party reviews
Best for: B2B companies, including smaller agencies, that want predictable appointment-setting costs through pay-per-meeting pricing without long-term contracts.
Choosing among these four comes down to what you're actually buying. If you want a single partner that runs outreach, paid ads, creative testing, and instant lead follow-up as one connected plan, Worqd is the clear pick, especially if you're sitting on a CRM full of old leads that nobody works. Their under-60-second qualification and pay-for-revived-conversations recovery model solve the exact problem most PPC agencies have: leads arrive fast and get worked slowly. If you want appointment volume from a large, established shop with a wide channel menu, Belkins is a strong choice, just ask for their qualified-meeting definition in writing. If you're testing outbound for the first time and want a month-to-month escape hatch, SalesHive's structure fits. And if budget is the constraint, ProspectOut's published $500 per month entry point and pay-per-meeting option make it the easiest way to dip a toe in. Whichever you choose, ask the same questions before signing: what counts as a qualified meeting, who owns the sending domains, and what happens after the reply. The agencies that answer those three clearly are the ones worth your budget.
Frequently asked questions
What makes Worqd different from a typical cold email agency?
Most cold email agencies stop at the reply. Worqd runs the whole path from first click to booked call: outreach and paid ads to generate interest, then AI SDR and voice agents that qualify every inquiry in under 60 seconds, 24/7. They also recover old leads from your existing CRM, and you only pay for the conversations that come back. It's a retainer-style growth partner rather than a single-channel vendor, so ads, creative, and follow-up all report through one plan.
How much does a B2B cold email agency cost in 2026?
Done-for-you email agencies generally run $1,000 to $5,000 per month, while omnichannel programs run $5,000 to $15,000, based on published guides from 2026. ProspectOut publishes a $500 per month entry point, OutreachBloom publishes $2,400 per month, and Hypergen starts around $5,000 with a six-month minimum. For comparison, a fully loaded in-house SDR costs $110,000 to $160,000 per year, which is why most agencies cost a fraction of hiring.
Does cold email still work for agencies in 2026?
Yes, but the bar is higher. Instantly's Cold Email Benchmark Report 2026 puts average reply rates at 3.43%, so volume alone doesn't win. What works now is verified lists, proper domain warmup with SPF, DKIM, and DMARC, personalized messaging, and fast follow-up when someone replies. SalesBread's own data suggests pairing email with LinkedIn, since their LinkedIn reply rates average around 20% versus under 1% for high-volume email alone.
What should I ask a cold email agency before hiring one?
Ask what counts as a qualified meeting, and get it in writing, including whether no-shows and cancellations count. Ask which channels they use besides email, who actually runs your account, where their contact lists come from, and who owns the domains and data if you part ways. Finally, ask when they'd tell you outbound isn't a fit. An agency that says yes to everything should raise a flag.
Can PPC agencies white-label cold email and outreach services?
Yes. Worqd offers white-label creative and outreach work specifically for agencies, including UGC-style ad creative and B2B cold email under the agency's brand. Other agencies on this list work with marketing agencies as clients, but Worqd is the only one here that explicitly builds white-label delivery into its service lineup.
How long does it take to see results from cold email outreach?
Expect 2 to 4 weeks of setup and domain warmup before real results, since sending domains need gradual ramping to protect deliverability. SalesHive reports most clients launch within about three weeks, and Hypergen claims a first lead within 7 days of campaign launch. Any agency promising meetings in week one is a red flag; the warmup period is a technical requirement, not a delay you can skip.
