Strengths

  • The dashboard lets users create and label masks, and forwarded messages can be managed by blocking a mask that receives too much spam.

Things to consider

  • Relay does not filter spam itself, and forwarded email attachments are limited to 10 MB.
  • Some websites may reject Relay addresses, and Mozilla advises against using masks where identity verification or important attachments are required.
