How to Fix Links in Emails Not Working

We have seen issues when a mailing service, such as SendGrid, alters links in emails. This could cause the links in emails sent by Simply Schedule Appointments to appear jumbled and lead to a 404 error page.

The Link Tracking function actually alters the body of links, which can cause issues with links in SSA emails.

To fix this when using SendGrid, go into your SendGrid settings and disable “Link Tracking” or “Click Tracking”. We also suggest that you contact SendGrid to let them know about this issue; tracking features like this should not cause 404 errors and will need review.

If you are experiencing this issue but not using SendGrid, check to see if you have any other applications that may be altering your links. This includes other mailing services or potentially even your host.

If you don’t see a setting for link tracking within your mailing service’s settings, you may need to contact their support to find out how to disable the tracking of links.
