Overview
MailWizz and Keila are both self-hosted email tools. MailWizz is a self-hosted PHP email marketing application with one-time license. Keila is a open-source email newsletter tool built with Elixir.
Approach
MailWizz is a commercial product with a one-time $86 license. It has been developed since 2013 with consistent feature additions including automation, A/B testing, and landing pages. Keila is completely free and focuses on open source.
Feature Comparison
MailWizz offers more out of the box: automation workflows, A/B testing, multiple delivery servers, white-label, and bounce management. Keila focuses on open source and eu hosting option.
Both require you to manage your own servers and configure email delivery. If you'd rather skip infrastructure management entirely, a managed platform like Sequenzy handles it all with SaaS-specific features like Stripe integration.
Making the Choice
Choose MailWizz for a feature-rich self-hosted email platform. Choose Keila for open source. For managed SaaS email, consider Sequenzy.
