Set up outgoing email Two separate jobs: how mail leaves your server, and what it says. Get delivery working first.
Webmail and mailboxes WBAMS can give your organization, clients, members and staff real mailboxes on your domain, and a webmail application to read them.
Notifications to Slack, email and phones Notification rules tell your team when something happens, a new order, a new ticket, a reply, by email, in Slack or HipChat, or by text message.
Email campaigns and the newsletter list Messages to many people at once: campaigns to an audience you define, a mass message for an announcement, and your newsletter subscriber list.
