Keila
Self-hosted newsletter tool with campaigns, forms, and segments behind an official JSON API.
Self-hosted · Keila Cloud XS: €8 per month · Keila Cloud S to XXL: €16 per month
- I send a monthly newsletter and want to stop paying per contact
- I want my agent to add subscribers from other systems and schedule campaigns over an API on a box I control
- Configure senders (SMTP, SES, Sendgrid, Mailgun, Postmark)
2 more jobs are undetermined.
- AGPL-3.0
- Elixir stack: fewer Adopters can make light edits than with a PHP or Node app
- API key must be generated in account settings before the API answers
- Sender configuration is not writable through the API
Mautic
Self-hosted marketing automation: contacts, segments, campaigns, and email, with an official REST API.
Self-hosted · Hosted trial and partners
- I want HubSpot-style drips and segments on my own server, with contacts I own
- I need my agent to add leads, tag them into segments, and trigger campaigns over an API
1 more job is undetermined.
- GPL-3.0 (GitHub shows NOASSERTION; composer.json says GPL-3.0)
- The REST API is disabled by default and must be switched on in Configuration > API Settings
- Segments, campaigns, and email sends depend on cron jobs; without them nothing moves
- README warns against running from the GitHub source in production; use the mautic.org package or Composer
- Requires PHP and MySQL versions matching the release's supported versions page
