Last updated on 18 Mar, 2026

For general information about Tracking, visit our feature page. If you are using a different email client, please refer to the corresponding guide for Apple Mail, Gmail or mobile, where you’ll find step-by-step instructions tailored to those platforms.


How do I use Open Tracking?

1. Make sure you that have Tracking enabled by default. Or enable it manually. For instructions see here.

2. Compose a new email and open the Mailbutler sidebar.
Please note that you need to keep the Mailbutler sidebar open when sending your email in order for Tracking to work.

3. Double-check whether Open Tracking is enabled in the sidebar. Depending on which email server you are using, you might have to enable it manually every time you are sending an email - even if it is enabled by default.


4. Send the email. Your email is being tracked.

How do I test Open Tracking?

If you would like to test whether Open Tracking is working correctly, you can send a test email with Tracking enabled to alex@mailbutler.io - Once the email has been opened, the open event should be recorded in your Mailbutler tracking details. This is a simple way to verify that tracking is functioning as expected in your setup.
