What Are Transactional Emails?

Transactional emails are triggered by user actions or system events. Unlike marketing emails, they’re expected, often urgent, and directly related to the user’s interaction with your product.

These emails have the highest open rates (often 60%+) because users are actively waiting for them.

Instant Delivery

Users expect these emails immediately. Delays are unacceptable.

High Priority

Password resets and 2FA codes are critical. They must arrive.

60%+ Open Rates

Users expect and want these emails. They actively look for them.

Inbox Placement

Spam folder delivery is a failed user experience.

Why Deliverability Matters

A password reset that lands in spam is a failed user experience

Speed

Reliability

Inbox Placement

Spam folder delivery is unacceptable. Users can’t find what they’re looking for and blame your product.

Best Practices

Ensure your transactional emails always reach the inbox

Separate Streams

Use different sending domains or IPs for transactional vs. marketing emails.

Keep It Simple

Clear subject lines, minimal design, focused content. No distractions from the purpose.

Include Essentials

Company name, contact info, and relevant details. Build trust with every email.

Test Thoroughly

Transactional emails are critical. Test all edge cases before going live.

Monitor Deliverability

Track bounce rates and act on issues quickly. Problems compound if left unaddressed.

Mind Expiration

Password reset links should expire. Include the deadline in the email.
