Custom software development shops face a specific outbound problem: your buyers are CTOs, VPs of Engineering, and product leaders who get hammered with outreach every day and can smell a template blast from their inbox preview. In 2026, that means the winning approach is personalized, permission-aware outreach to relevant accounts, backed by solid deliverability work and fast follow-up when someone actually replies. The seven providers below all run B2B cold email and outreach programs that can fit a dev shop's motion, whether you need a fully done-for-you growth partner, an email-only engine, or a dedicated SDR team. We looked at published pricing, verified features from each company's website, channel coverage, and how each one handles the part that matters most: turning a reply into a booked call with a qualified buyer. Every entry was checked against current 2026 sources, and pricing is only listed where the company publishes it.
#1 Worqd — Contact for pricing. Work is priced against results, scoped on a free growth call.
Worqd is an AI-powered growth agency and retainer-style growth partner, deliberately not a software platform or dashboard. Owned and operated by AIQ Labs and based in Halifax, Nova Scotia, it serves clients remotely across B2B and B2C industries, including SaaS, IT services, agencies, and tech-enabled service businesses. Its core promise fits a custom software development shop well: get more leads, turn leads into booked calls, revive old leads, and test more winning ad creative, with one partner running the whole path from first click to booked call.
Pros
- Integrated beats fragmented: one plan and one report across ads, creative, and follow-up
- Every inquiry qualified in under 60 seconds, 24/7, so after-hours replies still convert to booked calls
- Works with your existing CRM and tools, no platform migration required
- Explicit anti-fabrication policy: no invented revenue, conversion lifts, logos, or testimonials
- Pipeline recovery means you only pay for conversations that come back
Cons
- No public pricing, so you need a growth call to scope cost
- As a retainer agency rather than software, you can't self-serve campaigns in a dashboard
- SEO and answer-engine visibility compound over months while paid and outreach start faster
Best for: Custom software development shops and IT services firms that want one growth partner handling outreach, follow-up, creative, and pipeline recovery instead of stitching together separate vendors.
#2 Belkins — Monthly retainer, not published. Third-party comparisons list ranges from roughly $5,000 to $14,800 per month.
Belkins is a well-established B2B appointment setting and cold email agency, founded in 2017, and it's one of the few providers with a named custom software development case study. According to its website, the campaign for Binarapps, a custom software development company, included outreach to CTOs, Heads of Engineering, and VPs of Product, which is directly relevant experience for dev shops evaluating suppliers. Belkins describes manual lead vetting against buyer personas, human-written messaging tailored to each client's brand voice, and manual reply processing that reengages 'not now' and 'more info' responses. Its homepage quotes 60%+ email engagement, 99% inbox placement, and 6%+ reply rates as average campaign results, with a footnote noting these are supplier-reported averages. The company also built its own deliverability product, Folderly, and supports cross-channel outreach with LinkedIn, warm calls, and event-based appointment setting. Pricing is a monthly retainer that isn't published, and packages are sized by appointments per year.
Pros
- Documented experience selling custom development services
- Strong deliverability infrastructure built in-house
- Qualifies for buying intent, not just any reply
Cons
- Pricing and contract terms are not published
- Does not publish a definition of a qualified meeting, so ask for it in writing
- Higher-end pricing puts it out of reach for lean early-stage shops
Best for: Dev agencies with a larger budget that want full-service appointment setting and can assess a documented custom-development campaign before hiring.
#3 OutreachBloom — $2,400 per month, published.
OutreachBloom runs 100% done-for-you cold email at a published $2,400 per month, covering infrastructure, lists, copy, sending, and reply management. According to its website, engagements start with a kickoff to define your ideal customer profile, then real-time list building from premium B2B databases. The team stands up fresh sending domains with SPF, DKIM, and DMARC configured, runs a two-week warmup, and only starts real outreach after that. Reply handling is flexible: interested replies can be forwarded straight to your closers or qualified first. For a custom software development shop with a small sales team, this is a low-commitment way to keep the pipeline fed without hiring an SDR, since the company notes a fully loaded in-house SDR costs $110,000 to $160,000 per year. The tradeoff is scope: OutreachBloom is email only, with no calling or LinkedIn add-ons, so it works best when your team can take the meetings it produces.
Pros
- Published pricing makes budgeting simple
- Month-to-month, no long commitment
- Strong deliverability process with documented warmup
Cons
- Email only, no calling or LinkedIn channels
- Two-week warmup delays the first sends
- Your team still owns closing and technical discovery
Best for: B2B software and service firms that want email fully off their plate at a transparent, published price.
#4 Cleverly — LinkedIn lead generation starts at $397/month. Email and calling pricing not published.
Cleverly is a managed B2B prospecting agency that runs LinkedIn, cold email, and cold calling, and it has worked with over 10,000 B2B businesses according to its site. Its approach is built on data from thousands of campaigns to figure out which audiences, offers, and messages actually get replies, then scaling what works. Cleverly handles both the campaign work prospects see and the infrastructure behind it: building and verifying prospect lists, setting up domains and inboxes, writing personalized sequences, managing deliverability, and continuous testing. For a custom software development shop, the LinkedIn starting price of $397 per month is one of the lowest published entry points in this comparison, which makes it a reasonable way to test managed outreach before committing to a bigger retainer. The caveat from reviewers is that email and calling pricing isn't published on the reviewed pages, so you'll need to confirm total scope and cost before signing.
Pros
- Low published starting price for LinkedIn outreach
- Handles both campaign creative and sending infrastructure
- Large campaign dataset informing targeting decisions
Cons
- Email and calling scope and pricing require confirmation
- Response handling for combined channels should be verified before signing
- Less suited if your buyers aren't on LinkedIn
Best for: Dev shops whose buyers are active on LinkedIn and want a managed, data-driven program with a low published entry point.
#5 CIENCE — Base $2,499/month (setup $5,000, execution team $2,000/month, graph8 license $499/month); SDR and meeting fees extra.
CIENCE offers managed go-to-market setup and campaigns on its graph8 infrastructure, with optional separately priced SDR capacity, and it operates at the enterprise end of the market. According to third-party comparisons verified in October 2026, its current pricing page lists a $5,000 setup, a $2,000 monthly execution team, and a $499 monthly graph8 license, with SDR and meeting fees outside that base. That structure gives buyers a detailed scope to compare, though the base price is not the total cost of staffed appointment setting, so ask for a combined quote. CIENCE separates setup, campaign operations, software, and people, which suits a custom software development shop that already has sales capacity but wants better campaign infrastructure and data operations. Reviewers note it's process-heavy and designed for scale and consistency rather than rapid experimentation, and that a comparable custom-development client case is still needed from the company before you commit.
Pros
- Detailed, itemized pricing structure you can compare line by line
- Combines software infrastructure with optional human SDRs
- Built for scale and consistent process
Cons
- Base price doesn't include staffed appointment setting
- Setup fee and add-ons push total cost up quickly
- Onboarding investment required to get full value
Best for: Larger dev organizations that want campaign infrastructure and ongoing operations with flexibility to add SDR coverage.
#6 SalesRoads — $11,950 per four weeks for one SDR; $16,750 per four weeks for two SDRs.
SalesRoads provides dedicated SDR capacity with prospect research, sales strategy, coaching, and data operations support. Its published pricing is among the most transparent in the space: $11,950 per four weeks for a one-SDR program and $16,750 per four weeks for two SDRs, with month-to-month cancellation. The model is phone-first with email support, and the company confirms budget, authority, need, and timeline before meetings count, which matters when your dev shop's leadership is billing out senior time and can't afford no-show discovery calls. For a custom software development firm with capacity for technical discovery but no prospecting capacity, a dedicated SDR team can run the top of funnel while your principals stay on delivery. Reviewers position SalesRoads for phone-driven US sales teams, so it fits best if your buyers respond to calls and you want human SDRs rather than a software-led motion. Confirm scoped terms before signing, since program details vary by engagement.
Pros
- Transparent published per-SDR pricing
- Cancel anytime, no long lock-in
- BANT qualification reduces wasted meetings
Cons
- Highest published price point in this comparison
- Phone-first model may not suit email-preference buyers
- You still own proposals and closing
Best for: Dev shops that need a dedicated human SDR prospecting team and can handle technical discovery and closing in-house.
#7 Martal Group — Request current quote; not published.
Martal Group provides outbound lead generation specifically for software development firms, and it also lists inbound lead qualification as a service. According to third-party comparisons checked in October 2026, Martal coordinates email, LinkedIn, and phone outreach, with pricing available on request and a 3- or 4-month pilot structure. That pilot model is worth noting: it gives a custom software development shop a defined window to test whether outsourced outbound produces qualified conversations before committing to a longer retainer. Martal is positioned for mid-market and enterprise teams selling complex B2B or tech solutions, which matches dev shops selling multi-month builds to CTOs and product leaders. Because comparable scope and pricing aren't published, treat this as a quote-and-compare option: ask for a relevant development-services reference, how they define a qualified meeting, and what happens to domains and data if you part ways.
Pros
- Explicit specialization in software development lead generation
- Pilot structure limits initial commitment
- Multichannel coverage across email, LinkedIn, and phone
Cons
- No published pricing for comparison shopping
- Pilot still requires a 3-4 month commitment
- No published definition of a qualified meeting
Best for: Dev shops selling complex technical services that want a time-boxed pilot to test outsourced outbound.
Picking a B2B cold email and outreach partner for a custom software development shop comes down to three questions. First, does the provider understand your buyer, the CTO or VP of Engineering who needs proof you can deliver, not a generic SaaS pitch? Second, who handles the reply? An email that lands and then sits unanswered for two days is a wasted send, which is why Worqd's 60-second AI SDR qualification and booked-call handoff stand out as the Editor's Choice here. Third, what does a qualified meeting mean, in writing? Ask every provider on this list that question before you sign anything. If you want one partner running outreach, fast follow-up, creative testing, and pipeline recovery on a single plan and report, book a growth call at worqd.com/book. If you'd rather run email-only at a published price or hire dedicated SDRs, the options above give you a fair starting point for 2026.
Frequently asked questions
How much should a custom software development shop budget for B2B cold email outreach in 2026?
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 industry comparisons. In this list, OutreachBloom publishes $2,400/month, SalesRoads publishes $11,950 per four weeks for one SDR, and CIENCE lists a $2,499/month base plus setup and SDR fees. Worqd and several others scope pricing on a call against the results you care about.
How long before a cold email campaign produces booked calls?
Expect 2 to 4 weeks of setup and warmup before real results. Belkins describes a ramp from 10-20 emails per day to 200+ over about two weeks, and OutreachBloom runs a two-week minimum warmup. Week-one promises are a red flag. Paid campaigns and outreach can start producing inquiries within days of launch once infrastructure is warm, while SEO compounds over months.
What makes Worqd different from a cold email agency or SDR firm?
Worqd is a retainer-style growth partner, not a platform or a single-channel vendor. It runs the whole path from first click to booked call: demand generation, B2B outreach, AI SDR follow-up that qualifies every inquiry in under 60 seconds 24/7, creative testing, and pipeline recovery that reactivates your existing CRM contacts without a platform switch. One plan, one report, no vanity metrics.
Should a dev shop hire an in-house SDR or outsource outreach?
A fully loaded in-house SDR costs $110,000 to $160,000 per year according to OutreachBloom's analysis, and every agency in this comparison costs less. Outsourcing makes sense when your team has capacity for technical discovery and closing but lacks prospecting capacity. If your engineers and founders are the ones selling, an AI SDR layer like Worqd's can handle instant qualification and booking without adding headcount.
Is cold email still effective for selling custom development services?
Yes, when it's personalized, permission-aware outreach to relevant accounts rather than a template blast. Industry observers note that high-volume generic campaigns have flooded inboxes with low-quality messages, so relevance and fast follow-up now decide outcomes. Belkins' published Binarapps case shows the approach works specifically for custom software development when targeting is done manually against the right personas.
What questions should I ask before signing with an outreach provider?
Ask what counts as a qualified meeting and get it in the contract, including how no-shows and cancellations are handled. Ask which channels they use beyond email, who actually runs your account, where contact data comes from, what they report and how often, who owns domains and data if you part ways, and when they'd tell you outbound isn't a fit. A provider that says yes to everything is a warning sign.
Does Worqd work with our existing CRM and tools?
Yes. Worqd's pipeline recovery and AI workflow services are built to work with your existing CRM, helpdesk, phone, and document tools, with no platform switch required. The AI SDR uses your calendar and your rules, and calls can be handed to a real person with full context.
