One API call creates Google and Microsoft mailboxes, connects domains and writes SPF, DKIM and DMARC. The OAuth flow is fully automated, so provisioning finishes in about 10 minutes instead of waiting days on admin consoles.
Create official Google and Microsoft Business Starter mailboxes on demand, generate handles automatically, and return credentials straight to your app.
SPF, DKIM, DMARC and custom tracking domains configured instantly per domain, with one domain per workspace for clean isolation.
Push provisioned mailboxes into 50+ platforms including Instantly, Smartlead, ReachInbox, Reply and Lemlist over a fully automated OAuth connection.
Zapmail runs email infrastructure for 50,000+ businesses, and the same stack is available to your team through the API.
