I am using a service called sneakemail.com today, but it doesn't support using my own domain. Source: 6 months ago

To piggyback on this, for sites you might want to keep an email for be able to kill it if necessary, I use https://sneakemail.com . Create a brand new address for every site, all of which forward to your chosen email with the name you set. (Frex; go to WeSpamLots, create a new email named 'TheySpamLots' and when they send you email, it comes in as "WeSpamLotsNewsletter-at-wespamlots.com | TheySpamLots". Source: over 1 year ago

Https://sneakemail.com/ is another one that's been around for a long time. - Source: Hacker News / almost 2 years ago

That being said, I use a service called sneakemail.com to generate email aliases for my real email for things like account generation, or online purchases that require an email address. Source: almost 2 years ago

Some services block Sneakemail addresses because they consider them "disposable". That's sort of understandable if they have a legitimate reason to limit sock puppet accounts, like for an online poll, but I've run into paid services that block them for no reason at all (and, like ClouDNS, they never explain why.) Clearly they don't want my business. Source: almost 2 years ago

If you don't like anonaddy specifically I think most VPN's have email forwarding now too and there other competing services like simplelogin.io, altmails.com, forwardemail.net. Source: about 3 years ago
