API integration for email send (Microsoft Graph, Gmail API)
We currently configure SMTP relays for clients who wish to send email from their own domains.
However, it is often challenging to work with client IT teams to enable SMTP AUTH on the required mailboxes.
In these situations, we are frequently asked whether SmartSimple supports — or plans to support — integration with Microsoft 365 (Graph API) or Gmail API for outbound mail delivery.
We understand that the February upgrade strengthened security by enforcing OAuth 2.0 for SMTP authentication. However, this still relies on SMTP as the transport protocol, which many IT providers increasingly consider legacy compared to modern API-based approaches.
Please consider supporting outbound mail via Microsoft Graph API or Gmail API.
