Transactional Email Triggers are automated emails sent in direct response to a user’s transaction or account-related action. Unlike marketing emails, transactional emails are expected by recipients and contain information essential to completing or following up on a specific interaction with your business.
Characteristics of Transactional Emails
What Makes Them Different
- User-initiated: Triggered by recipient’s own action
- Expected: Recipients anticipate receiving them
- Time-sensitive: Often contain urgent information
- High open rates: Typically 40-50%+ open rates
- Exempt from some regulations: Often don’t require unsubscribe links
Legal Considerations
While transactional emails have more regulatory flexibility:
- Primary purpose must be transactional
- Marketing content should be minimal (under 20%)
- Must still include sender identification
- Should not be deceptive
