# Transactional Email
We use SendGrid (opens new window) to have our application deliver email to users, known as transactional email (opens new window).
Examples of transactional email are:
- Confirmations
- Follow ups after the first 3 days of use
- Free trial is expiring
- Message another user in the system
We use SendGrid directly, not via the Heroku add-on, in order to avoid being lumped under the same IP group as others on Heroku (who might be misbehaving).
