Done-for-You Cold Email Specialists
These agencies focus specifically on cold email execution. They handle the technical infrastructure (domains, warmup, deliverability), list building, copywriting, and sending—allowing you to focus entirely on closing deals that come through.
1. OutreachBloom
Positioning: Cold email 100% done for you—all you have to do is close the deal.
OutreachBloom is a B2B cold email agency that runs outbound entirely on your behalf. They handle domain setup, email warmup, list building, copywriting, sending at scale, and even reply management by default. The model is designed for teams that want meetings without managing any outreach infrastructure themselves.
Their process starts with a kickoff call to define your ICP, followed by real-time list building using premium B2B databases. They set up fresh domains with proper DKIM, DMARC, and SPF authentication, warm them for two weeks, then launch personalized outreach. Clients can choose whether OutreachBloom handles replies or passes warm leads directly.
Best for:
- B2B SaaS companies wanting outbound without hiring SDRs
- Agencies selling services to other businesses
- Professional services firms (consultants, accountants, lawyers)
- Teams that want zero involvement in outreach mechanics
- Companies prioritizing email-only outreach over multichannel
- Teams struggling with deliverability and/or maintaining email infrastructure
Who should look elsewhere:
- Enterprise companies needing phone + email + LinkedIn orchestration
- Teams wanting to run outreach in-house with agency guidance
- Companies requiring dedicated SDRs assigned to their account

2. ColdIQ
Positioning: Full-funnel outbound and LinkedIn growth for B2B tech companies that want steady pipeline, not random leads.
ColdIQ helps B2B tech companies book qualified meetings using a mix of cold email, LinkedIn outreach, LinkedIn ads, and content. Instead of running one channel in isolation, they connect everything into one simple system so interest from ads or content turns into outbound follow-ups and sales conversations.
They handle the full setup: defining your ideal customer, building lead lists, writing messages, setting up tools, and launching campaigns. Most clients see campaigns live within about 2 weeks, with pipeline building over the first 1–3 months as results compound.

Frequently Asked Questions
How much do cold email agencies typically cost?
Pricing varies widely based on service scope. Email-only agencies may charge $1,500-$5,000/month. Full-service omnichannel agencies with dedicated SDRs typically run $5,000-$15,000/month. Enterprise-level services with AI platforms and multiple channels can exceed $10,000/month plus setup fees. Some agencies offer pay-per-lead or pay-per-meeting models for more predictable costs.
How long before I see results from a cold email agency?
Most agencies require 2-4 weeks for setup, including domain warming, list building, and messaging approval. First meetings typically appear within 1-14 days after launch. Full campaign optimization and predictable results usually take 60-90 days. Agencies that promise immediate results may be cutting corners on deliverability, which can harm your domain reputation.
Should I choose email-only or omnichannel outreach?
Email-only works well for straightforward B2B sales where prospects respond to written communication. Omnichannel (email + phone + LinkedIn) typically produces better results for complex sales cycles, high-value deals, or when targeting executives who are difficult to reach via email alone. Email-only is also more affordable and simpler to manage.
What’s the difference between “done-for-you” and SDR-as-a-Service?
Done-for-you agencies handle everything from list building to reply management—you just show up to meetings. SDR-as-a-Service provides dedicated sales development representatives who work as an extension of your team, often requiring more coordination and oversight. DFY is hands-off; SDRaaS involves more collaboration.
Will cold email damage my domain reputation?
Reputable agencies use separate domains for outreach (not your primary domain), proper warmup protocols, and authentication (SPF, DKIM, DMARC). They send at appropriate volumes with clean lists. Agencies that skip these steps or send from your main domain can damage deliverability. Always confirm that the agency uses separate infrastructure.
How do I know if leads are qualified?
Quality varies by agency. Ask about their qualification criteria, whether they hand-verify leads against your ICP, and how they handle responses. The best agencies define qualification standards during onboarding and only book meetings with prospects matching your criteria. Request sample lead reports or case studies showing lead-to-opportunity conversion rates.
