koigrid vs AWS SES
Transactional email with your own provider — the no-lock-in alternative to AWS SES.
SES is cheap but means DKIM records, a sandbox, bounce handling and IAM before your first email. koigrid takes the model Vercel and Railway use: bring your own SMTP (Resend, SES, Postmark, your own server) and we relay through it — your reputation, your domains, no markup.
| Feature | koigrid | AWS SES |
|---|---|---|
| Setup | Paste your SMTP string | DKIM + sandbox + IAM |
| Sending reputation | Yours | Yours |
| Domain limit | None (your provider’s) | None |
| Provider lock-in | None — swap any time | AWS |
| Send by API / AI agent | Native | API (complex) |
