Zapmail provisions Google Workspace and Microsoft 365 mailboxes built for cold outreach: domain purchase or connection, automatic mailbox naming, SPF/DKIM/DMARC and tracking domains, and export to more than 50 sending tools. It reports over 1M mailboxes and 330K domains set up, and offers pre-warmed accounts plus aged domains.
Product Overview
Zapmail is one of the larger players in the Google/Microsoft cold-email mailbox category. Beyond provisioning, it adds tooling around the problem: deliverability tests, AI insights credits, ZapShield and ZapSites for domain protection and landing pages, and AI helpers for choosing domain names, naming mailboxes and generating profile photos. Each domain lives in its own workspace to isolate reputation. For RevOps the relevant point is scale: an API positioned as headless infrastructure for SaaS products and AI SDR platforms, not just for individual senders.
RevOps Jobs-to-Be-Done
- Provision outbound infrastructure at scale — Buy domains, auto-create mailboxes and push them to the sequencer in one flow. KPI: Hundreds of inboxes live without manual workspace or DNS work.
- Launch with pre-warmed accounts — Pre-warmed mailboxes and aged domains let campaigns start sending from day one. KPI: No multi-week warmup delay on new programmes.
- Embed mailbox provisioning in a product — The API lets SaaS and AI SDR platforms create and manage mailboxes programmatically. KPI: Infrastructure becomes a backend service rather than a manual task.

Good fit if:
