Xem is an open-source email marketing suite. It brings campaigns, recurring newsletters, visual automations, signup forms, a contact CRM, a shared inbox and analytics into one app. It sends through Amazon SES or any SMTP provider, so sending costs what your provider charges rather than a fee per subscriber. You can use the hosted app at app.xem.email or run Xem on your own server under the GPL-3.0 licence. The source is on GitHub.

What Xem includes

How sending costs work

Xem does not charge per email. Your provider does. Through Amazon SES that is $0.10 to $0.16 per 1,000 emails, so a weekly newsletter to 10,000 people costs about $4.00 to $6.40 a month to send. The Amazon SES guide covers setup and pricing plans.
