I used to like sneakemail. They forwarded an email address I created to another that the site was unaware of. I had so many email addresses and I could block particular ones if I saw a site was spamming me. Then they went pay. $3/month was a bit much so I looked for something else.
I now use spam gourmet. I went to the site years ago to create a base account.
Now I sign up "some word".x. "my username" @ spamgourmet.com
I get to choose the word so for here, I might choose PCHelpForum
The email address would be PCHelp.7."my username"@spamgourmet.com
I don't have to go to the spamgourmet site to create new addresses. They'll know it is me by my username and start forwarding whatever arrives.
x is some number I select between 1 and 20 for the number of emails I want forwarded. If it is an unimportant site, I choose 1. If it is a site I might have an interest in, I can choose 5, 10 or even 20.
I can go back to spamgourmet and change the number associated with a particular email address.
I've probably been using this for 10 or more years.
spamgourmet
I just went in to look at my stats there
Your message stats: 94 forwarded, 1,110 eaten. You have 30 spamgourmet address(es).
That's a lot of spam I never got.
