A: Great question! Some differences between SimpleLogin and a catch-all domain:

- Better experiences: you can easily create a new alias in SimpleLogin everywhere.
- You can easily reply to a forwarded email or send an email from your alias. Most catch-all domain doesn't provide this.
- SimpleLogin supports multiple mailboxes which isn't the case for most catch-all domain provided by ISP
- SimpleLogin supports PGP
- You have a better control over your domain with the new SimpleLogin "Auto Create" feature (basically a regex based rules for auto-creating aliases)
