&gt; <i>but I still get disposable emails, which is kind of aggravating.</i><p>From the other side:<p>So is giving up my e-mail address to receive something, knowing I&#x27;m going to get e-mail later about other things that I don&#x27;t want (a.k.a. &quot;spam&quot;, to some people).<p>I run my own mail servers, though, so I just create a new alias for everything, such as these one-off &quot;give us your e-mail and we&#x27;ll give you x&quot; offers. I generally don&#x27;t delete them afterwards, though, unless and until I start receiving other unrelated e-mails. Then, they get deleted (technically: timestamped and marked inactive in the database) and after a year they &quot;reactivate&quot; and become spamtraps.
