Troubleshoot Broken Links

If you see broken or misdirected links in your Mailchimp campaign, read about some of these common causes.

Incorrect Link Formatting

If web links in your campaign don't begin with the http:// or https:// protocol, they may have broken after click tracking was added.

This link is missing the http://
This link is missing the two forward slashes after http:

If Google Analytics, e-commerce, or ClickTale tracking are enabled for your campaign, improperly formatted links can cause issues.

Our system makes sure your links are formatted correctly if you use Mailchimp's link building tools. However, if you create a custom-coded template, you or your designer are responsible for verifying that your link formatting is correct.

When you add these link tracking methods to your campaigns, always test your campaign and use the Link Checker tool to ensure your links work as expected.

Unaccepted query strings

Some of our available link-tracking features utilize query strings to pass information about a specific campaign back to your Mailchimp reports or to a third-party service or plugin. When you use these various link-tracking methods, first ensure that your website is configured to accept these parameters.

If Google Analytics tracking is enabled for your campaign, your website needs to be set up to handle the following Google Analytics parameters.


If you're not sure that your website is configured to handle these strings, forward this information to your webmaster to verify and troubleshoot further. Otherwise, you'll want to disable the additional tracking method(s) being used for the Mailchimp campaign.

Links are redirected to

We've seen this happen when an email passes through a very aggressive spam filter, like in corporate or academic settings. To avoid potential attacks, the spam filter breaks our tracking code and doesn't allow redirects.
