Pre-warmed mailboxes

Skip the warmup window. Plug pre-warmed Google and Microsoft accounts straight into your campaigns and start sending the same day.

🛡

Workspace-level isolation

One domain per workspace, with DNS records, forwarding and tracking domains configured automatically instead of by hand.

🔌

Headless API

Provision domains and mailboxes programmatically from your own product. Built for SaaS platforms and AI SDR teams.

Zapmail runs the mailbox, domain and DNS layer so your team can focus on the conversations, not the configuration.
