The record

Service: 33Mail creates private email aliases and forwards their messages to an existing email address.
Alias creation: Aliases are created automatically when an email is first sent to them.
Alias controls: Users can block an alias to stop receiving its email.
Anonymous replies: With anonymous replies activated, users can reply to forwarded mail through 33Mail, which removes header information relating to their actual email address.
Creation limits: The FAQ states alias creation is limited to 5 per 30 minutes for Lite, 20 for Premium, and 50 for Pro.
Attachments: Forwarded emails can include attachments up to 10MB, which count toward monthly bandwidth.
Bandwidth window: Bandwidth limits are calculated over a rolling 30-day window.
Over-limit handling: 33Mail says it will send a warning if a user exceeds the bandwidth limit and treats dropping emails as a last resort.
Data policy: The terms say 33Mail will not share user data with third parties except as necessary to comply with law enforcement requests, and will use it to provide the service.
Support: The help page offers email support for feature requests and problem reports and directs users to send a direct message to @33mail on Twitter.
