Mailchimp alternatives compared
Listmonk edges Keila 98 to 93, and most of the difference is stars: 24k stars against 2.3k stars.
The most recent release is Keila 0.40.0, published yesterday. None of the measured options scores under 40. By stack, PHP (3), Go (1) and Python (1) are the most common. Dittofeed is permissively licensed; Listmonk, Keila, Mautic and 2 more are copyleft. Sendy is source-available rather than open source, which limits commercial reuse. Sendy and Mailman are not hosted on a forge Repoly can read, so they have no measured score yet.
