Feature: screen to send e-mail to users

[a-surfer]

Rather often we need to send e-mails about BeeHub to (part of) our user community (e.g.: BeeHub is down, your sponsor is going end-of-life...). It is currently a lot of hand work to fetch the user list, plus, the way to go is to copy-n-paste many stuff in your favourite e-mail client. And after all, it's your personal inbox that gets full with all the different communications.

Since we are already sending e-mails from BeeHub (e.g.: you've got an invitation to a group, you are now part of this sponsor...), it shouldn't be difficult to make a screen that will allow to send e-mails from within the BeeHub platform as well.

I would suggest the following requirements:

• Sender can be 'support@beehub.nl' or so
• Reply-to can be 'support@beehub.nl'
• Recipient should be the individual user (so forget about the BCC), properly formatted, like: 'Name Surname something@example.com'
• Subject should be '[BeeHub users]' or so
• The interface should allow to look for users (e.g.: per name, per group, per sponsor, select all...)
• By default, delay actually sending the message for 5min (or make it otherwise configurable per message), so that after you click "send", you can still correct the "damn it!, I forgot this".
• Keep history of sent e-mail messages.
