MailFlow | Newsletters, Automations & Email Builder for WordPress

MailFlow is a newsletter system that lives inside WordPress: build the email with a drag-and-drop builder, grow lists with a sign-up form and double opt-in, send campaigns and automated series through the relay you already use, and read opens, clicks and bounces in the same place. No subscriber fees, no external editor, your list stays in your database.
