Transactional email
You may need an email sending service for your application to send automated email to your users, known as transactional email. We recommend: SendGrid. (Free-$400/month)
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
Note this is not the same as your business’ email.
