Keila
Open-source newsletter tool for campaigns and sign-up forms, sending through your own SMTP or email API.
Send campaigns through SMTP, AWS SES, SendGrid, Mailgun or Postmark.
Keila is an open-source alternative to newsletter tools like Mailchimp or Sendinblue. You send campaigns and create sign-up forms, using your own inbox for small lists or an email API for larger ones.
What it is
The README lists SMTP, AWS SES, SendGrid, Mailgun and Postmark as sending options, and an official Docker image plus a sample Compose file. A hosted Keila Cloud option exists at app.keila.io.
Who it's for
It suits small teams and developers who want to send newsletters from infrastructure they control. It does not suit anyone who needs paid subscriptions, a website builder or a reader network.
