I am building an email with a link a url that contains an anchor such as:

However, when the email is sent the utm tracking source is inserted before the # like this:

meaning the user is sent here:

I have tried http://www.mywebsite.com/customer-service%23delivery-information which returns a 404 error.

Does anyone know how I can link to a URL that contains an anchor? or do I need to create redirects for such links?
