I want to transition my over 2200 masked emails from IronVest to Proton email.
I'd like to Import Ironvest Masked emails via CSV to create Hide-my-email aliases.
Obviously Proton can't use the same masked email address, so it's mass creating new Hide-my-email aliases.
I'm not using Proton Pass & Auth yet.
And yes, it will take me forever to change all those email addresses. But I'd start with my most active ones.
