What Keila is

Keila is open-source email marketing software for managing contacts, building signup forms, and creating personalized newsletter campaigns. You can compose campaigns in a visual block editor, Markdown, MJML, or plain text. Signup forms support custom text fields, checkboxes, dropdowns, and tags. Audience segments can draw on custom contact data and campaign interactions, using either a visual editor or a query language. Personalization uses Shopify Liquid templates and JSON custom data, including in subject lines. You can track opens and clicks or switch tracking off; Keila says its tracking does not use IP addresses or cookies. Sending options include SMTP, AWS SES, Mailgun, Postmark, and SendGrid. An API supports managing contacts and campaigns and automating email workflows. Keila is available as a managed Cloud service or AGPLv3-licensed self-hosted software, with an official Docker image. The Cloud service runs on European infrastructure in Germany and France. There is no free plan. Paid plans start with Keila XS at €8.00 per month, billed monthly, for 2,000 emails per month; every listed plan includes unlimited contacts and projects.
