Frontend for addressees to see via web the messages they've received.
To be able to add a link to each sent email like: "Can't see this message? Click here to see it in your browser"
Should be secure: Generated links to see each email should be secured with a unique, strong hash so only the individual addressee knows it. If not implemented properly, it could easily lead to a serious bug where anyone can see any sent message.
Was just reading a newsletter from Sideshow Collectables and thinking that's something to implement long term "Having Trouble? View web version" which would be exactly this.
Thanks, @Organizer21 ! It is! It would be really nice to have this option, and should be easy to implement, since the emails are already being stored on the database. A security mechanism should be implemented to ensure that only the recipient of the message can see the email online. A great way to implement such mechanism would be to generate a long hash unique to each message, and require that hash as a get parameter on the web request to emailqueue. Emailqueue should check that hash against the requested message id before showing the email.
