Following up on T100454, we need to standardize and document the process for mass electronic mailings. The documentation part of this can probably take the form of a Meta-Wiki page that outlines at least:
- the need to exclude users who have opted out of all mailings (there's an opt out page... somewhere)
- the need to (often) exclude bots and other non-human accounts
- the need to give sufficient warning time to people doing the work (including translators writing e-mail body content, developers updating the relevant scripts, and sysadmins running the relevant scripts)
There may also be a technical component to this task in standardizing how these lists are generating (the various PHP scripts, including doSpam.php and sendMails.php), but that will require further investigation, research, and consultation.
