Email forwarding services

1. I do! I've been using AnonAddy (I did chuckle at your typo there!) for about a year.
2. I'm on their free plan but it works great. I don't think I've ever had a delivery issue. That being said, my email volume over the service is very minimal. Maybe 20 emails a month.
3. Despite being happy with AnonAddy though, I am slowly migrating to iCloud+. Since iOS 15, Apple started offering a feature called Hide My Email as part of their iCloud+ subscription, which I have been using because Apple's extremely stingy with storage. The feature is not tied to an iDevice, you can set and manage things from iCloud's web interface and it works pretty well. I don't know if you can create random email addresses using your own domain, but you can and I did set the destination address to my custom email. It is, as you'd expect, a barebones experience but I find it really reliable.

In addition to both services I mentioned, I also used Firefox Relay during its beta phase (I migrated my addresses to iCloud+ a week before the service was out of beta). I wouldn't recommend Firefox Relay at all. It's even more barebones than iCloud+ and frankly, I do not trust Mozilla to keep the service up.

If you don't already have an iCloud+ subscription, I'd wholeheartedly recommend AnonAddy. Even if you don't use many of its features, it's a product created to do one thing and those tend to be more reliable and worth supporting.

Alternatively, If you're using 1Password, it recently started to offer a masked email service integrated with Fastmail. (Both of these services are excellent.) If you're not using either of these services, migrating to them might be more hassle than its worth, but if you are, well, you're in luck.

Last year or so I started using wildcard email addresses. Grab a cheap .com. I use Zoho, which is cheap. I went with a .party that I registered for a decade, but not all sites like a .party.

Since starting this system I've yet to receive any spam, which is a miracle.

There's always the concern of you not renewing a domain, but for me, I'm more concerned about a third-party service going down. If Zoho goes under, there are plenty of other email hosts I can easily migrate to.

DuckDuckGo’s Email Protection service recently entered beta. Can sign up for the private beta on their mobile app. They let you generate infinite private addresses for free. They also automatically strip trackers (Mail Chimp, Send Grid, etc). I’m a big fan of it, especially not needing an account to use it.

If you want to avoid a 3rd party solution, buy a domain. The registrar should support email forwarding. Namecheap has it for free if I remember correctly.

There's always sneakemail. They have been around for a long time. In addition to random email addresses, they also offer keywords, which you can use to hand out a new email address on the fly, without even needing a computer. You can also create outgoing random emails, to send an email to some entity who you'd prefer not see your real email. It costs $3 a month.

Something that's served me well for a few years now is just adding +label to a normal email address. For example, if your real primary email is alcappuccino@yourdomain.com, then you would provide alcappuccino+servicename@yourdomain.com when making an account on servicename.com . Almost all email infrastructure on the Internet (servers, relays, whatever) accept that, and it ends up in your normal alcappuccino@yourdomain.com inbox, except the To: field is clearly showing alcappuccino+servicename@. That way, you can filter however you wish.

A small asterisk: A tiny few things online won't accept emails with + in them. But I've found that that's very rare. In my case, I make a full-blown email alias at my email provider in such situations. This takes a bit more effort, but it happens rarely enough that I don't mind.

Do you use any of these three services?

I use Fastmail's built-in Masked Email feature. Previously I've been using a custom .com domain with catch-all, but ended up regretting having to pay for yet another domain, since I'm already paying for a personal domain with my name/surname (which I use for communicating with actual humans). I know I'm losing address portability, but all things considered I'm happy with my decision[1].

How happy are you with the service that you use?

So far, I'm happy. I wish Fastmail's Masked Email feature was more prominent in their app, because I use that frequently. Instead, they buried it inside settings. A browser extension prompting me to use masked addresses would be awesome, but as of now nothing like that exists.

Is there something better?

As others have said, if you're already in the Apple ecosystem you would probably be better off with iCloud+'s Hide My Email.

[1] By the way, you can use Masked Email with a domain of your choice, instead of the usual fastmail.com.

I use AnonAddy, and I'm quite happy with the service.
I have never noticed any mail delivery issues, and I appreciate the configurability (several recipients, custom domains) and the ability to respond via the aliases.
I'm paying for the pro tier.

I haven't really used any other services, but did use + and . for adding labels for a while.
That would still expose my "actual" email address, though.
And if one of the labelled addresses end up on a spam list it might be a hassle to actually get it blocked, depending on your email service provider and/or email clients.
In AnonAddy, it's just a matter of flipping a switch for the leaked alias address in the control panel, and it'll stop forwarding them to my actual email address.

My likely naïve take on this is that email forwarders create that much larger an attack surface. I can reasonably trust that it's very unlikely that Google or Microsoft or Yahoo will suffer an attack that will expose my data through means I didn't influence negatively (bad passwords, for example). DDG or Mozilla are smaller organizations, and if they're filtering all of my emails before they get to me, my email account is only as secure as they are.

You could use multiple email addresses, but the real trick is to make sure that if one account is compromised, no others are able to be accessed using those same credentials. In the event my account is compromised, I have 2FA on enough of my services that allow it that this provides extra protection. Even if Google is unlikely to be compromised like this, it only has to happen once for it to have happened.

Another consideration is that GMail, at least, and maybe others, allow the following: "username+subname@gmail.com." From there you can sign up with your Google username, append extra data (+subname) and effectively self-organize your emails by the service they came to. I assume you could also update existing services to be, say, username+spotify@gmail.com so that from today forward you'll know if any janky emails came to be sent because of something at Spotify.

I'm sorry it's not advice about which service to use, but frankly all I can see a service like this doing is spreading you out more.

Edit: I was wrong about email addresses being shared with Gravatar without needing an account with them. See my edit below.
