You might use this crisis as motivation to adopt a one unique email per account setup via simplelogin.io or addy.io
You'd have to burn your leaked email and create a new personal one but it will provide a bulwark should any more account details get leaked.
Thank you for the recommendations!
Happy to help.
For phone number segregation you might consider something like mysudo, JMP.chat or Cloaked.
Some of these phone services also offer disposable emails too.
One thing I'd recommend doing if you're not trying to remain highly anonymous is registering your own custom domain name for all the email aliases you'll be generating. That was you can take them with you easily should you opt to switch to another provider or even self host if so inclined. (Addy.io offers their software as a free self hosted option).
It goes without saying that you'll need a robust password manager to keep track if all your unique account emails and passwords.
I pretty much moved all my e-mail to my own domain and was doing what you recommended. The legacy email is just something that had a long history and was tied to my identity and it's a bit of a pain to completely dump it at this point. In terms of phone numbers, I just use a VOIP as my default for general screening, never give out my actual number. So, everything that comes in there I know is not valuable.
