SendGrid is a mature email platform owned by Twilio. Truncus is an independent EU-hosted execution layer with multi-provider failover, delivery guarantees, and no platform lock-in.
SendGrid runs on Twilio's US infrastructure. Truncus runs on EU providers (SES Ireland + Brevo France) with automatic failover. Your data stays in the EU by default.
