the Gmail “+” trick all the time. Let’s say your email address is bob@bobsmith.com. After signing up for services or newsletters, how can you tell who’s sharing your email, or contain the damage if someone discovers your login email? Companies get hacked all the time. Just use + as cheap insurance. If you append + and a word to the beginning, messages will still get delivered to your inbox. Signing up for Instacart, for instance? You could use bob+insta@bobsmith.com. I use this, or benefit from it, on a daily basis.
