Latest Updates
September 4 - October 6, 2026
A faster, more resilient API that stays quick even at peak traffic - plus configurable DMARC checks for the Mail API, WhatsApp templates with media headers and a new partner portal at affiliate.seven.io.
Send SMS from your inbox, your way
The Mail API now gives every configuration its own fixed address and lets you describe your mails with patterns instead of bending them to our subject syntax - plus a live preview with real test mails and up to ten allowed senders per configuration.
Build your own OAuth app, skip the sender ID paperwork
Connect third-party tools to your account without ever handing out an API key, and file the sender ID paperwork regulators want straight from your dashboard - plus a smoother RCS launch and contact groups everywhere.
