Sendersy vs SendGrid: a Resend-compatible alternative with EU + RU residency
SendGrid pioneered email infrastructure but has become expensive, requires verified sender domains, and stores data in the US. Sendersy fixes all three.
Sendersy
$0 for 3 000 emails/mo → $20 for 50 000 emails/mo. No hidden caps on domains or API keys.
SendGrid
$0 for 100 emails/day (3 months only) → $19.95 for 50 000 emails/mo → $89.95 for 100 000.

Migration FAQ
Can I reuse my SendGrid templates in Sendersy?
Yes — export the HTML from SendGrid and import via POST /api/dashboard/templates with the html field. The {{name}} variable syntax is identical.
Does Sendersy support SendGrid Inbound Parse?
Partially. Sendersy ships a Mailcow stack for inbound mailboxes (info@ / support@ / noreply@), but MIME payload webhook forwarding to your app is on the roadmap.
