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 |

| 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.
Is my data hosted in the EU?
Yes. koigrid is EU-hosted (on Hetzner) with data sovereignty by default.
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.
