Transactional email with a Resend-compatible API: send emails, manage broadcasts and domains.
Quick Install
Automated & IDE SetupCopy the AI prompt to install this server into Claude Code, Cursor, or another agent — or use 1-click editor setup below.
One-click editor setup isn’t available for this listing yet — we don’t have a confirmed install command, and we’d rather show nothing than point your editor at the wrong package or host. Follow the project’s own setup instructions, linked above.
Manual Client & Custom JSON ConfigExpand JSON ▾
No confirmed setup config for this listing yet. We only publish a config block when the install details come from the project itself — its README, its docs, or a verified owner. We haven’t found those for MepMail, and we’d rather show nothing than a guess you’d paste into your client. Follow the project’s own setup instructions for the current steps.
Documentation Overview
Transactional email with a Resend-compatible API.
Self-host on your own AWS SES, or use the hosted cloud at mepmail.je4ndev.com. Migrating from Resend means changing two environment variables — not rewriting your integration.

Run it locally
Build from this source checkout:
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.
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.
