Lol- this is so funny, I was going to ask if there was a way to email your other guild members & found this!
For my case, my guild has a discord page but I'm sure there are tons of guild members who have not joined the discord & don't really pay attention to the daily guild message in ESO, so if we want to send a message to everyone- like reminding everyone of our weekly activities or that we're working together on the #TamrielTogether project, it's a bit difficult to let everyone know outside of the discord!
For PC there are addons like Shissu's and GodSend...but those do result in bans sometimes, especially if you're in a newbie guild where people don't understand that reporting the GM for updating you on guild events isn't the solution to "stop spam" (where spam = once a week mail)

I clicked Other for the fact I don't get the ban hammer like some do but I do agree there needs to be a better way of communicating to your guild by some messaging system within the game.
