Why are some e-mail programs flagging my e-mail as a potential phishing e-mail?
When you activate "Click-through Rate" reporting for an e-mail newsletter on the first page of the "Compose Newsletter" wizard, we save the links in your e-mail to a database and replace them with a redirect link to count clicks.
To avoid that some overzealous spam filters show phishing warnings (because the actual destination, the redirect link, is different from the visual domain), don't use domain names in the visible description of links.
