Settings

Three steps and your emails go out through Lettermint:

1. Go to Settings → Email.
2. Set Transport Type to Lettermint.
3. Fill in the settings below and save.

Standard settings

Setting	Required	Description
Project API Token	Yes	Found on your projects page under “API Token”.
Route Slug		A custom route. Leave blank for the default transactional route.
Tags		Tags for all emails, e.g. environment=production, campaign=welcome. Use only letters, digits, _ and -.

Caution

The System Email Address must use a domain you set up in Lettermint.

Tip

All settings support environment variables.

Pro settings

With the Pro edition, more settings appear below the standard settings. All of them are optional, so turn on only what you need.

Setting	What it does
Team API Token	Unlocks the Team API features. Team owners create it in the dashboard under Manage team → “API Tokens”.
Project	ID of the project your Project API Token belongs to. Needed for project details, statistics, domains and checks.
Webhook Secret	Turns on the webhook endpoint.
Health Token	Turns on the health endpoint.
Sites	Sets a route and tags per site.

Note

Lettermint can’t tell which project a token belongs to, so set Project yourself.
