HEADLESS EMAIL INFRASTRUCTURE

Mailboxes live in 10 minutes, fully automated

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.
