Introduction
Use Lettermint to send transactional and broadcast email, receive inbound email, and manage email infrastructure through APIs, SDKs, or SMTP.
Choose an interface
SDKs and frameworks
Send email or manage team resources with an official package.
SMTP
Send from applications and devices that support SMTP.
Inbound mail
Receive parsed email through signed webhooks.
Team API
Manage domains, projects, routes, webhooks, and suppressions.
Send your first email
Complete these steps before you run an example:
-
Create your account
Sign up at app.lettermint.co.
-
Create a Project API token
Create a project, then create a token and store it in
LETTERMINT_PROJECT_TOKEN. -
Send your first email
Install an official SDK, or use cURL.
Never expose Project API tokens or Team API tokens in client-side code or public repositories.
Every project can have multiple Project API tokens. Create one token per app, worker, or environment so you can rotate credentials independently.
