Questions regarding custom domains and email aliases

Questions

I’m thinking of using a custom domain for all my email communications that are more or less tied to my real identity. The problem is I’m having trouble coming up with a solid strategy when aliasing is thrown into the mix. I’m currently using Tuta with addy.io. Here’s what I was wondering:

  1. I feel like it’d be safer to use my main Tuta email instead of an Addy alias for things like banks or governments since I want to minimize the number of parties I have to trust. Is this a valid concern? I know email is inherently insecure, but I still feel like I should be taking extra measures in this kind of context.

  2. Let’s say I end up using Tuta for those bank/government accounts and Addy for everything else. Would I be able to use my custom domain for both my main Tuta email and for my Addy aliases? Or can I only point my custom domain to one specific service at a time?

  3. I know using a custom domain gives you more control over your email address since it makes switching between providers easier. Is that also true in the case of aliases? For example, if I ever decide to stop using Addy, would there be an easy way to switch my custom domain aliases over to something like SimpleLogin?

Thanks!

  1. Yes, trusting multiple parties is a valid concern. Whether it’s worth it is for you to decide but I would still use aliases for all my accounts in your situation.

  2. No you can’t use the same domain at multiple email providers but you can use the domain at Tuta and a subdomain at addy.io. For instance example.com and addy.example.com.

  3. I don’t know if exporting across provides as you describe is possible (it might very well be, I have no clue) but regardless you avoid lock-in by owning the domain. The worst case is you create a catch-all address (*@addy.example.com) at some new provider so you can continue to receive all your email while you work on changing your accounts.

A lot of the posts I read through while researching this (like this one) seemed to recommend the same alias-only approach so I’m tempted to try it. I’ll have to look into it further and decide if I want to stay with Addy (which I don’t use much at the moment) or switch to SimpleLogin depending on the features.

Yeah that makes sense. I looked into this further and it turns out Addy’s FAQ page already addresses this among other things.

That’s definitely reassuring. Thanks!
