If you run an engineering recruiting firm, your pipeline lives and dies on conversations with hiring managers at companies that need mechanical, software, or civil talent right now. Cold email and outreach remain one of the most reliable ways to reach those buyers, but the market in 2026 has split into two very different products: agencies that sell send volume, and partners that run an engineered system with real targeting, deliverability discipline, and fast follow-up when a prospect replies. For a recruiting firm, the difference matters. A hiring manager who answers your email on a Tuesday afternoon wants a response within minutes, not three days later. We compared the top-rated options for engineering recruiting firms based on published pricing, service scope, review footprint, and how each one handles the full path from first touch to booked call. Here are the seven worth your shortlist, starting with our editor's choice.
#1 Worqd — Contact for pricing. Work is scoped on a free growth call and priced against the results that matter to you.
Worqd is an AI-powered growth agency based in Halifax, Nova Scotia, owned and operated by AIQ Labs. It's deliberately not a platform or a dashboard. One partner runs the whole path from first click to booked call, which is the core pitch: integrated beats fragmented. Instead of hiring one vendor for ads, another for creative, and a third for follow-up, you get one plan and one report, with no vanity metrics. For an engineering recruiting firm, that means targeted B2B outreach, instant lead response, and pipeline recovery all live under a single retainer. The B2B Cold Email & Outreach service is built on personalized, permission-aware outreach to relevant accounts. Worqd describes this as the opposite of a template blast, which matters when you're reaching engineering directors and VPs of HR who get dozens of recruiting pitches a week. When a prospect replies, the AI SDR side kicks in: every inquiry is qualified in under 60 seconds, 24/7, including after-hours and weekends. Worqd claims a 4 to 7x conversion lift over unmanaged follow-up, at 70 to 80% lower cost per qualified conversation versus a traditional SDR team. Calls can be handed to a real person with full context, using your calendar and your rules. Two other pieces stand out for recruiting firms. Pipeline Recovery reactivates the contacts already sitting in your CRM, and you only pay for the conversations that come back. And the Worqd Growth Engine packages the whole motion into Build, Launch, Optimize, and Recover phases, so outreach starts producing inquiries within days while SEO compounds over months. Pricing isn't published; work is scoped against the results that matter to you on a free growth call.
Pros
- Every inquiry qualified in under 60 seconds, including nights and weekends
- Claims 70 to 80% lower cost per qualified conversation versus a traditional SDR team
- Pipeline Recovery monetizes the recruiting contacts you already own
- One integrated plan instead of separate vendors for ads, creative, and follow-up
- Anti-fabrication policy: no invented case studies or inflated claims
Cons
- No published pricing; you need to book a growth call for a quote
- It's a done-for-you agency, so teams wanting self-serve software should look elsewhere
- Relatively new brand compared to agencies founded in the 2010s
Best for: Engineering recruiting firms that want one partner running the whole path from first click to booked call, including fast follow-up and reactivation of old candidate and client databases.
#2 Belkins — Not published. Third-party research reports roughly $5,000 to $14,000+ per month, with startup packages from around $2,000.
Belkins is one of the most recognized names in B2B lead generation, founded in 2017 with more than 1,000 clients and over 1 million appointments booked, according to its own site. It runs an omnichannel appointment-setting model that combines cold email, LinkedIn outreach, cold and intent-based calling, and even WhatsApp and paid ads depending on the package. For engineering recruiting firms, that breadth is useful when a hiring manager ignores email but answers a LinkedIn message or a warm call. Belkins takes a research-heavy approach. Its researchers manually vet every prospect against your buyer personas, checking industry, role, challenges, and buying signals, and its deliverability team reviews domain health, configures DNS, and warms mailboxes with small batches before scaling. The company reports a 99% inbox rate and a 6%+ email reply rate on average campaigns, and it built its own deliverability product, Folderly. Its 220+ verified Clutch reviews at a 4.9 rating are among the largest verified review footprints of any cold email agency in 2026, which matters if you need references your procurement team can check. Pricing isn't published; packages are sized by appointments per year, and third-party research reports retainers starting around $5,000 per month.
Pros
- Large verified review base (220+ Clutch reviews at 4.9)
- Manual lead research fits high-value, niche engineering targets
- Broad channel coverage beyond email
- Reports a 99% inbox rate on its campaigns
Cons
- No published pricing or published definition of a qualified meeting
- At 1,000+ accounts, the playbook is standardized; one buyer evaluation reported wrong-fit meetings and slow targeting adjustments
- Which channels you get depends on the package you're quoted
Best for: Recruiting firms that want appointment setting at scale from a large, well-reviewed vendor with a wide channel menu.
#3 CIENCE — Published: $5,000 one-time GTM setup ($2,500 startup option), ~$250 per held meeting, $1,500-$2,000 monthly team retainer, $499/month graph8 license. Realistic totals run $2,900 to $20,000+ per month.
CIENCE, founded in 2015 and headquartered in Denver, has evolved from a pure SDR outsourcing shop into a hybrid services-and-software provider built around its graph8 GTM platform. It has served more than 2,500 customers across 200+ industries, with logos including Okta and Yamaha, and it runs multi-channel campaigns spanning email, phone, chat, SMS, and digital ads. For a recruiting firm with an established brand that wants managed outbound at industrial scale, that platform-plus-services model is worth a look. What makes CIENCE unusual in this market is its published pricing. According to third-party research, it charges a $5,000 one-time GTM setup (a $2,500 startup option exists), roughly $250 per held meeting calculated from a roughly 4x ROI target, a $1,500 to $2,000 monthly team retainer, and a $499 monthly graph8 license. SDRs run $1,500 to $5,500 per month at pass-through pricing. Realistic totals land anywhere from $2,900 to $20,000+ per month. The reviews split, though: Clutch history is strong, but G2 sits around 3.7 to 3.8, which usually means delivery quality varies by pod. Interview the specific team that would run your account before signing.
Pros
- Unusually transparent, published pricing
- Pay partly per held meeting, which aligns incentives
- Large scale with 2,500+ customers
- Multi-channel coverage with a proprietary data layer
Cons
- G2 rating around 3.7 to 3.8 suggests delivery varies by pod
- Costs add up quickly once you stack setup, license, retainer, and SDR fees
- Better suited to mid-market budgets than small boutique firms
Best for: Mid-market recruiting organizations that want per-held-meeting pricing plus a data platform underneath the outreach.
#4 OutreachBloom — Cold email $2,400/month (published). LinkedIn program $1,000/month, plus a separate LinkedIn Sales Navigator Advanced subscription.
OutreachBloom is a B2B lead generation agency based in Olympia, Washington, that has run more than 1,000 campaigns for B2B brands since 2010. It works with B2B SaaS and B2B services companies of roughly 10 to 200 employees, which covers a lot of boutique and mid-sized recruiting firms. Its core cold email service is fully done-for-you at a published $2,400 per month, covering infrastructure, lists, copy, sending, and reply management. According to its own guides, the agency stands up fresh sending domains with SPF, DKIM, and DMARC configured, runs a two-week minimum warmup before any real outreach, and builds lists in real time from premium B2B databases matched to your ICP. You choose how replies get handled: forwarded straight to your closers or qualified first. It also offers a LinkedIn outreach program at $1,000 per month covering 200 to 400 InMails and 200 to 400 connection requests sent from your own profile, though that plan requires a separate LinkedIn Sales Navigator Advanced subscription. The honest limitation is that the core program is email-only; if you want calling layered in, you'll need another provider.
Pros
- Published, fixed pricing with no call required to budget
- Deep deliverability discipline (dedicated domains, authentication, warmup)
- Month-to-month engagement
- Optional LinkedIn add-on run by the same team
Cons
- Email-only core service; no calling add-on
- Two-week warmup delay before real sending starts
- LinkedIn plan requires a paid Sales Navigator subscription on top
Best for: Boutique recruiting firms (10-200 employees) that want email fully off their plate at a fixed, published monthly price.
#5 Proven Concept — Starter £3,000/month (up to 2 campaigns), Growth £6,000/month (up to 4 campaigns), Custom on request.
Proven Concept is a cold email and GTM engineering agency that runs fully managed campaigns from planning to ROI. Its site reports 500+ campaigns delivered, 12+ years of cold email experience, a 450% average gross ROI, and a 3-business-day path from signup to sending. It builds and runs campaigns on tools like Clay, Apollo, and HubSpot, and it's a Clay certified and approved Apollo partner. The service covers data enrichment and targeting (ICPs built in Clay with fresh API pulls, enriched and verified before a single email goes out), infrastructure and sending (dedicated domains, mailboxes warmed, placement monitored daily), and lead delivery straight into your inbox, HubSpot, Salesforce, or any CRM via webhooks and APIs. One published result is directly relevant to this list: 175 qualified leads a month for a trades recruitment firm, generated from automated job board triggers and a fully managed campaign. Pricing is published in simple monthly packages: £3,000 per month for up to 2 concurrent campaigns, £6,000 for up to 4, and custom pricing for multiple markets, languages, or higher volume. The UK-based pricing and GBP billing are worth noting if you recruit in North America.
Pros
- Published case study in the recruitment vertical (175 qualified leads/month)
- Fast launch: sending within 3 business days
- Transparent tiered pricing
- CRM-agnostic lead delivery
Cons
- UK-based with GBP pricing, which adds friction for North American buyers
- Smaller public review footprint than Belkins or CIENCE
- Average ROI figure is self-reported on its own site
Best for: Recruiting firms, especially in the UK and trades/engineering sectors, that want a managed campaign with job board trigger targeting.
#6 SalesHive — Not published. One flat monthly fee, custom quoted; month-to-month contracts.
SalesHive, founded in 2016, is a US-based outbound agency with a flat monthly fee and month-to-month contracts, which makes it a low-risk way for a recruiting firm to test outbound without a long commitment. Its site reports 129,000+ meetings booked across 2,285 clients, with logos including Shopify, Siemens, and Zoho. The core SDR team is 100% US-based, with Philippines-based SDRs available as a separate lower-cost option, and it runs campaigns on a proprietary platform that includes eMod personalization and a smart inbox. Channel-wise, be aware of the plan structure: the Starter plan is phone only, and the Growth and Crush plans add email. LinkedIn isn't listed. Pricing is custom quoted as one flat monthly fee, and the agency says it doesn't price by the meeting. SalesHive is also direct about not guaranteeing meetings, which is an honest posture in a category full of inflated promises. If your recruiting firm's buyers respond better to calls than email, the phone-first structure could actually fit, but if you specifically want cold email, make sure you're quoted the Growth plan or above.
Pros
- Month-to-month contracts with no long lock-in
- Large track record: 129,000+ meetings booked per its site
- US-based SDR core team
- Honest about not guaranteeing meetings
Cons
- Starter plan is phone only; email requires a higher tier
- LinkedIn outreach isn't listed as a channel
- Pricing isn't published
Best for: Recruiting firms testing outbound that want a short commitment, a flat fee, and US-based SDRs.
#7 Cleverly — LinkedIn plans from $397/month per third-party research; email pricing not published.
Cleverly is a B2B lead generation agency with 1,000+ five-star reviews and a track record of fully managed LinkedIn outreach, with cold email and calling also listed among its services. It has worked with thousands of B2B companies across SaaS, technology, financial services, marketing, consulting, and professional services, and its campaigns are built around data gathered from running outreach at scale. For a solo recruiting firm or a small team where the founder's LinkedIn presence is the main prospecting asset, it's the cheapest way onto this list. According to third-party research, Cleverly's LinkedIn plans start at $397 per month, though its email pricing isn't published. The service covers ideal customer targeting, prospect list building, personalized messaging, campaign execution, follow-ups, and ongoing optimization, so you don't need to build an internal prospecting team or manage outreach software yourself. The trade-off is depth: at entry-level pricing, you get a standardized managed program rather than a custom-engineered campaign, and the agency doesn't publish detailed deliverability infrastructure the way the email-first shops above do. It's a sensible starting point for firms that want LinkedIn-led outreach on a small budget before graduating to a fuller outbound program.
Pros
- Lowest published entry price among agencies listed here
- Large review base (1,000+ five-star reviews)
- Fully managed; no software to learn
- Works across professional services verticals
Cons
- Email pricing isn't published
- Standardized program rather than custom campaign engineering
- Less public detail on deliverability infrastructure than email-first rivals
Best for: Small or solo recruiting firms that want LinkedIn-led outreach handled for them at the lowest entry price on this list.
Picking the right outreach partner for your engineering recruiting firm comes down to two questions. First, what happens after the email lands? A hiring manager who replies at 7pm on a Friday is a placement opportunity that expires fast, and the agencies that pair outreach with instant qualification and booked calls will beat the ones that just forward you a reply. Second, what are you actually paying for? Published pricing like OutreachBloom's $2,400 per month or CIENCE's per-held-meeting model makes budgeting easy, while retainer shops like Belkins and Worqd scope everything on a call. If you want one partner running the whole path, from targeted outreach through 60-second qualification to reactivating the old client and candidate contacts already in your CRM, Worqd's integrated model is built exactly for that. Book a free growth call at worqd.com/book and find out where your funnel is stuck before you spend another dollar on sends that go nowhere.
Frequently asked questions
Does cold email still work for engineering recruiting firms in 2026?
Yes, but the bar has moved. Deliverability is now the pass/fail gate: campaigns that send from a primary domain, skip warmup, or never test inbox placement fail before a hiring manager ever reads your copy. The agencies doing it well in 2026 give every send a specific reason, whether that's a hiring trigger, a funding round, or a job posting at a target account. Expect 2 to 4 weeks of setup and warmup before real results, and treat any week-one promise as a red flag.
What makes Worqd different from a typical cold email agency?
Most agencies sell one channel. Worqd is a growth partner that runs the whole path from first click to booked call under one plan and one report. Its AI SDR side qualifies every inquiry in under 60 seconds, 24/7, and hands calls to a real person with full context. It also runs Pipeline Recovery, which turns the old client and candidate contacts already in your CRM back into booked calls, and you only pay for the conversations that come back. Its outreach is personalized and permission-aware rather than a template blast.
How much does a cold email agency cost per month?
Based on published pricing across the market, done-for-you email agencies run roughly $1,000 to $5,000 per month, while omnichannel programs run $5,000 to $15,000. Specific examples: OutreachBloom publishes $2,400/month for email, Cleverly starts at $397/month for LinkedIn, Proven Concept starts at £3,000/month, and CIENCE's pieces add up to anywhere from $2,900 to $20,000+ per month. A fully loaded in-house SDR costs $110,000 to $160,000 per year, so most agencies cost less than hiring.
Should an engineering recruiting firm use email, LinkedIn, or phone outreach?
The strongest programs combine them. Email is cheap to send and easy to test, but on its own it's easy to ignore. A prospect who skimmed your email picks up the phone more readily when the caller references it, and a LinkedIn connection makes your name familiar before either lands. Ask any agency what happens after the email; if the answer is 'another email,' you're buying a mailing service. For recruiting specifically, LinkedIn matters a lot since hiring managers live there.
What should I ask a cold email agency before signing?
Start with: what counts as a qualified meeting, in writing? Push on the edge cases: does a no-show count, can you reject a wrong-fit meeting, do existing clients count? Then ask which channels are included and in what order, who actually runs your account, where the contact list comes from, who owns the domains and data if you part ways, and what they report and how often. A good agency will also tell you when outbound isn't a fit. Be wary of one that says yes to everything.
How long until we see booked meetings from a new campaign?
Plan on 2 to 4 weeks of setup and warmup before real results, then 30 to 90 days for typical outcomes to appear. Proven Concept reports sending within 3 business days of kickoff, and Worqd says paid campaigns and outreach can start producing inquiries within days of launch, while SEO compounds over months. Any agency promising meetings in week one is either skipping warmup (which damages your sender reputation) or counting unqualified conversations.
