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.

| 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) |

Frequently asked questions
Is koigrid cheaper than AWS SES?
koigrid is flat-rate with bandwidth included — no per-GB egress or per-request fees. For a comparable setup you usually pay a lot less (see the estimate above).
Can I migrate from AWS SES without lock-in?
Yes. koigrid runs on portable primitives — standard PostgreSQL, S3-compatible storage and containers — so you can move in (or out) whenever you want.
Where is my data hosted?
In data centers in the EU, on servers we run ourselves. The privacy policy says exactly where.
Can I run everything from an API or an AI agent?
Yes — koigrid is API-first and agent-native: every action has an API and a scoped token, with llms.txt and OpenAPI so an LLM can operate it end to end.
