Get started with Email Guardian

Email Guardian automatically scans your selected emails every 24 hours for email client changes that affect your content. Email Guardian notifies you of any major changes that might impact your subscribers' experience.

NOTE: We monitor your email for changes in the Chrome webmail clients for Gmail, Yahoo!, Outlook, and Outlook 365 Desktop clients. During the early access program, you may monitor as many emails as you would like!

Start monitoring an email

Go to the Email Guardian section at the top left of the Litmus home page and select Get started now.

Start monitoring an email without Previews & QA

If your Previews &. QA tab has not been added for your email, you will be prompted to run a set of previews. This provides a baseline view of your email for the Email Guardian to use.

From there, you will be taken to your Previews & QA test address. Send your email from your ESP to your Litmus test address to automatically run your baseline set of previews.

Once your initial previews are available, you can start monitoring the email.

Turn on email notifications

Once you have selected emails to monitor, you will need to turn on notifications.

NOTE: Email monitoring notification permissions need to be turned on in each account or subaccount you wish to receive notifications from.

From the main Email Guardian screen, select Notifications to opt in to receive guardian emails.

Email Guardian alert types

Major Impact found

When a major impact is detected you will be alerted by email once the change is detected. We will alert you of each individual major impact detected across your monitored emails.

Weekly Change Report

If you have any outstanding Major or Minor changes among monitored emails, we will alert you weekly. If no outstanding changes are detected, you won't receive a weekly change report.

Monthly Summary

The monthly summary will be sent each month of any changes found. This report is sent monthly, even if changes were not detected.

Minor vs. major issues

We compare screenshots of your email at different times and determine the degree to which the rendering has changed. We also detect specific rendering problems, such as broken images.

If we determine the rendering has changed a small amount from the original, we call it a minor change. This might include one or two images not loading.

If the change has a significant impact, we report it as a major change. This might include all of your images not loading.

NOTE: If your email has dynamic images, it could trigger an Email Guardian notification. If this is the only change you see, dismiss the alert with the corresponding dropdown option.

Investigate detected issues

When you are notified about a major impact, you can investigate it further by selecting the Investigate the change button in the alert email.

In Email Guardian, use the red slider to compare the previous copy of your email to the detected change.

If you decide the change doesn't require any intervention, you can choose the Dismiss alert button in the upper right above your email. Select an option from the dismissal list to help Email Guardian improve its scans.

If you want to correct your email, go to your original email code source, whether Builder or your ESP, to update your content. Once the issue has been corrected, submit a new version of your email using the green New version button in your Litmus Previews & QA tab. Copy your retest email address from the popup and use it to send your email from your ESP.

NOTE: It may take up to 24 hours for the new version of your email to be reflected in Email Guardian.
