If you are using Cloudflare to protect your website from unwanted traffic and spam then you will have come across this issue. Cloudflare obfuscates email addresses present on any page of the website so that spam bots are unable to access them. This is enabled by default and you don’t need to do anything at your end.
If you, however, need to disable email obfuscation on a web page for some reason then you can simply enclose that section in the following HTML comment tags.
Any email address which comes in this section will not be obfuscated and spam bots will be able to read it easily.

Hope the above helped!
