- bad_user 9y agoYes, unfortunately that's the truth. For example: meetup.com On an email with a plus in it, they complain with this exact error message: "This isn't a valid email address". I contacted their support a year ago. They replied that they've passed along my "feedback". Nothing happened since then. That said, plus aliasing is sort of a standard. And spammers could eliminate anything after the plus, its usage being pretty obvious, so you can't rely on it for tracing spam. Eliminating the aliasing is much trickier to do with sub-domains, as it's not at all clear when aliasing is used or not. And some email services support custom email routing based on your own regular expressions (e.g. GSuite) so you can come up with your own weird scheme. Plus aliasing is only fine when you don't have control for doing something better, more opaque. Like when you have a work or a @gmail.com address.
