If you send a link by email, the links will be changed by the recipients. The recipients are first taken to another page, which in turn redirects to the correct page.

The reason for this is that we use SendinBlue as a mail delivery service and this "tracks" the clicks on the links.

This turns example.com into the link r.sb.ifnormatik.com/< random numbers and letters>.

You don't need to be afraid that this will have any negative effects on you. This means that even your customers can be sure that the email is coming from you. If this link does not look like this, the email was not sent from our servers.
