"Page Not Found (404 Error)" when Accessing Links on a Marketing Campaign

When communicating via HTTP, a server is required to respond to a request, such as a web browser's request for an HTML document (web page), with a numeric response code and an optional, mandatory, or disallowed (based upon the status code) message. In the code 404, the first "4" indicates a client error, such as a mistyped URL.

To correct this error perform the following steps:

1. Navigate to Lists > Marketing > Marketing Templates.

2. Edit the Marketing Template.

3. In the HTML code locate the URL which normally starts with www (e.g. www.mywebsite.com).

4. Add http://  to the URL instead of just www (e.g. http://www.mywebsite.com).

5. Check the Send Email Preview checkbox.

Note: This is checked by default.

6. Click Save.

7. Check email client for the email preview to verify that link works.

Note: This is just one of the many possible causes of 404 errors. If using the Publishable Form URL of a custom record, for example, make sure that permission settings were configured correctly for external users to access the form.
