View performance metrics for transactional emails

You can track the performance of your transactional emails — receipts, password resets, and other automated messages — all in one place.

Availability

This capability may need to be enabled for your account — contact support if you don’t see it.

Viewing transactional email metrics

For each type of transactional email you send, you can see:

• Sends — total number of emails sent
• Open rate — percentage of recipients who opened the email
• Click rate — percentage of recipients who clicked links in the email
• Bounce rate — percentage of emails that failed to deliver
• Spam rate — percentage of emails marked as spam
• Refused — how many emails the sending provider would not send (a count, not a percentage)
• Last sent — when this email type was most recently sent

Filtering your data

Use the search and date filtering options to focus on specific transactional email types or time periods.

This helps you identify delivery issues, measure engagement with automated messages, and ensure your transactional emails are reaching your audience effectively.

See each send and why one was refused

Under each tag, choose Show sends to open a list of that tag’s newest 100 sends in the date range you’ve selected. Each row shows the send ID, its status — queued, accepted, refused, delivered, bounced, or marked as spam — the reason for any refused or bounced email, and when it was last updated. Choose Hide sends to close the list. Changing the date range closes any open list, so you never see rows from the previous range.

The send ID is the same uniqueId your send request returned, so you can match a row to a specific email. Developers can also look a send up through the API.

Prefer to just ask?

You can also ask Letterhead’s AI assistant how your transactional emails are performing, and get the same metrics grouped by tag for any date range.

1. Connect an AI client such as Claude Desktop to Letterhead’s MCP server.
2. Ask in plain language, for example:
   • “How are my transactional emails doing this month?”
   • “Show me password reset email performance for the last week”
   • “How did receipts perform in June?”

The assistant returns send counts, open rates, click rates, bounce rates, and spam rates, grouped by tag. Mention a specific time period in your question to get metrics for a custom date range.
