What are transactional messages?

In the world of email, there are two types of business email: marketing and transactional. Your business probably sends both. The main difference between them is that marketing email is often sent in bulk, while transactional emails are triggered.
You probably send transactional emails and SMS already, if you:
- Follow up on your recipient's purchase / download / conversion;
- Keep your recipient up to date about their purchase / download / conversion;
- Create overviews about your recipient's purchase / download / conversion;
- Send standardized emails to employees (i.e. paychecks).
Common types of these emails include, but are not limited to, order confirmations, password resets, multi-factor authentication, Track & Trace, notifications, end of trial, paychecks, and invoices.
