Transactional emails are automated messages sent to individual users in response to specific actions or events. Unlike broadcasts, these emails are triggered by user behavior and are highly personalized, making them essential for user engagement and business operations.

​
What are Transactional Emails?

Transactional emails are automated, one-to-one messages that are triggered by user actions or system events. Common examples include:
  • Welcome emails when users sign up
  • Password reset confirmations
  • Purchase confirmations and receipts
  • Shipping notifications and tracking updates
  • Account activity alerts
  • Subscription confirmations and renewals

​
Templates vs Custom Emails

Flywheel supports two approaches to transactional emails:

​
Email Templates

Templates are pre-designed email layouts that you can reuse across multiple transactional emails:
  • Reusable Design: Create once, use for multiple email types
  • Consistent Branding: Maintain brand consistency across all communications
  • Variable Support: Use placeholders for dynamic content
  • Easy Management: Update the template to change all emails using it

​
Custom Emails

Custom emails are built from scratch for specific use cases:
  • Unique Design: Completely custom layout and styling
  • Specific Purpose: Tailored for particular transactional scenarios
  • Full Control: Complete control over HTML, CSS, and content
  • One-time Use: Designed for specific email types or campaigns
