Use email aliases to test your opt-ins
Chances are you've signed up to your own form or landing page before, just as a test. This is a great way to verify exactly what a new subscriber will experience when they sign up to your list. However, you only have so many email addresses to use for testing. That's where email aliases can help.
Email aliases are a simple and convenient way to "pretend" that you're using a new email address, while still receiving the emails to the same inbox. All you have to do is add a + sign and then some text at the end of the first part of your email.
For example, if your email address is [email protected], then while testing you can use:
yourname+1@gmail.com
yourname+formtest@gmail.com
yourname+productlaunchtest@gmail.com
NOTE: Many major email providers (including Gmail and G Suite addresses) support email aliases, but not all of them. Be sure to double-check whether this is supported by your email provider before using this trick!
