Thanks in advance

maybe is a advert link from a email you get
only way emclient will go to it

If you have your privacy settings enabled (they are by default) in Menu > Settings > Mail > Privacy, then eM Client won’t follow any links in your messages unless you actually click on them. So check on that.

The only other way eM Client will go to that page is when sourcing contact avatars. You can disable that in Menu > Settings > Contacts.
