Transactional email with a Resend-compatible API.
Self-host on your own AWS SES, or use the hosted cloud at mepmail.dev. Migrating from Resend means changing two environment variables — not rewriting your integration.

Run it locally
Build from this source checkout:
git clone https://github.com/JE4NVRG/mepmail.git mepmail
cd mepmail
cp .env.example .env
Fill the two required secrets in .env before boot (MASTER_ENCRYPTION_KEY and
BETTER_AUTH_SECRET; generate each with openssl rand -base64 32).
The supported installation path is a local source build (root Dockerfile /
docker-compose.yml); third-party installers or prebuilt images are not
supported release channels for this project. The source wizard (pnpm setup:aws)
and the full SES/SNS event pipeline are documented in the
self-hosting guide.
docker compose up --build -d
Dashboard at http://localhost:3000, API at http://localhost:3001.
Migrating from Resend
Keep your Resend SDK: point its baseUrl at your MepMail instance and swap the
API key. The wire protocol is compatible, so request shapes do not change.
