Rot Algorithm in Python

A while ago I wanted to send a bunch of emails to building companies in order to get some quotes and/or information. Unfortunately, the website in question ( doesn’t provide emails in clear text to allow me copy/paste. Instead it uses a Rotating cypher algorithm (I guess it must be simple enough to be able to be decrypted by a browser).
