Sending providers

Send through the email account you already have.

Emerge has no mail servers of its own. Every campaign, automation and site email goes out through a sender you connect — a mailbox, an email API, or any SMTP server — with your domain, your reputation and your provider’s pricing. Connect several and Emerge rotates between them and fails over.
