Hello,
According to [SimpleLogin | FAQ]
Can I use email aliases for important services like bank, government, etc?
The short answer is yes you can. We use email aliases to run our business, manage our taxes, handle our bank operations and so far so good :).
A longer answer is the email protocol is designed to be highly resilient and an email is almost never lost. If SimpleLogin cannot deliver the email to your mailbox, we will notify you so you can take appropriate action.
But I don’t understand what this paragraph is referring to:
You can also set up a secondary mailbox in addition to your primary mailbox that can be used as a backup.
Can someone clarify what they are referring to? How can we configure a second backup address?
