Changing Email Help

Hello, I have already made a new email account, and for every new email have been using aliases so I can easily block spam. I have a lot of accounts related to my old address, and have changed some of the addresses over to the new one. However, there are so many, and I don’t want to forward everything as the reason for changing was due to spam emails. Is there a way to view all of the senders addresses that are using/ have my email? So I can decide what to change. I just don’t want to miss something and then lose access forever!

Many thanks & apologies if this is wrong place to ask - pls redirect me if so!

I don’t think there is any way to figure that out beyond exporting all of your email (if your provider allows it) and then looking at where they all came from in a .csv or something.

What I do is forward them all to my newer email under a specific address (junk@customdomain.tld) and set a rule on the new account to forward everything from that address to its own folder. Then I just pick through that periodically for important stuff and swap those over to the new email. You could possibly do a similar thing with plus/period addressing but I have not tried.

Honestly I would recommend forwarding your email long term anyway because you are bound to miss some. Others may disagree with this though.
