Overview
SendGrid, part of Twilio, is one of the largest email platforms, with a transactional API, marketing campaigns and a long list of features for big senders.
Rimbra’s Email API is smaller and simpler: transactional email, templates, broadcasts and a delivery log, set up in minutes, sitting next to your app hosting, database, domain and WhatsApp API.

Questions
Is Rimbra a SendGrid alternative?
For transactional email, templates and broadcasts from your own domain, yes. Very large senders that need dedicated IPs may still prefer SendGrid.
