Postalion

Postalion sends newsletters from your own WordPress site. Your subscribers stay in your database, there is no outside account, and the free plugin has no limit on subscribers or emails.

It covers what a small site needs: sign-up forms (block, shortcode, popup, slide-in, a form under posts), double opt-in, lists, tags and custom fields, twelve email templates, a welcome email, new-post emails and a weekly digest, open and click statistics counted on your own server, and a log of every email sent. Mail goes out through your host or any SMTP service (Brevo, Amazon SES, Mailgun, Postmark, SendGrid).

It moves your list over from Mailchimp, MailPoet or Newsletter, and works with WooCommerce, Easy Digital Downloads, course plugins (Tutor LMS, LifterLMS, LearnDash), memberships (Paid Memberships Pro, MemberPress), GiveWP, Event Tickets and eleven form plugins.

An optional paid add-on, Postalion Pro, adds a drag-and-drop builder, automations, sequences, segments and WooCommerce emails such as abandoned cart reminders.
