Zapmail
Cold email infrastructure, set up in minutes.
What is Zapmail
Zapmail provisions and manages cold email infrastructure — spinning up Google Workspace or Microsoft 365 mailboxes, configuring DNS records (SPF, DKIM, DMARC, MX), and running email warm-up automatically. It's built for SDRs, BDRs, agencies, and GTM engineers who need to operate multiple sending domains without manual DNS work or per-mailbox setup overhead. The standout capability is pre-warmed mailboxes with 12 weeks of warm-up already completed, letting teams skip the ramp period and start sending at volume faster. Mailboxes export with one click into tools like Instantly, Smartlead, and Reply.io, keeping it compatible with most outreach stacks. Where it stops being a fit: Zapmail is infrastructure, not a sequencer — it doesn't write copy, manage contacts, or run campaigns, so you'll still need a separate outreach tool on top.

Vanderbuild take
Zapmail is a focused deliverability infrastructure layer — not a sequencer, not a CRM — and for agencies or GTM engineers managing cold email at scale across multiple clients or domains, it does that one job cleanly. On the agentic side, the REST API is available on the Pro plan, which means you can wrap mailbox provisioning into your own automation or MCP layer; it's rated Capable, so expect solid programmatic control without a native agent interface out of the box. Pricing starts at $39/month for 10 mailboxes, which is affordable for small teams, but costs climb as you add mailboxes beyond the included allotment — budget accordingly if you're running 50+ sending accounts. The honest limitation is that API access is gated to the $299/month Pro tier, so smaller teams on Starter or Growth plans are UI-only, which limits how far you can automate provisioning workflows without upgrading.
