Here’s why you’ll love Keila

Emails That Just Work

Creating emails that work across devices and clients can be difficult. With Keila’s rock-solid base templates, your newsletters always look great – no matter if recipients are using Gmail, Outlook, Thunderbird, if they’re on mobile, or on a desktop computer.

Create Emails Your Way

  • You don’t want to code and prefer to design your newsletter in an easy-to-use visual editor? Keila’s powerful Block Editor is the right choice for you.
  • You love the simplicity of Markdown? With Keila, you can write newsletters with Markdown directly or use our Markdown-powered WYSIWYG editor.
  • Prefer plain text? Send your HTML-free no-frills emails with Keila.

Powerful Analytics and Great Privacy Options

Keila’s email analytics give you all the insights you need to make the most of your campaigns - while still respecting user privacy and not collecting more than is necessary and useful. If you prefer to be even more privacy-conscious, you can easily turn off tracking entirely.

Create Forms with Custom Fields with Our Flexible Form Builder

With Keila’s Form Builder, you can create and design sign-up forms for your newsletter. Customize your forms with additional checkboxes, text fields, and dropdowns.

Protect Your Newsletter from Bots

Any online form attracts bots. And when bots sign up to your newsletter, it negatively impacts the quality of your contact list and might ultimately jeopardize the deliverability of your emails. With Keila, you can easily protect your forms with a captcha check and verify new sign-ups with double-opt-in.

Personalize Emails with Custom Data and Liquid Templates

Keila makes it easy to personalize campaigns with the custom data fields from your sign-up forms or from external sources (e.g. CMS or CRM systems). Custom data for every contact and every campaign is represented as a single JSON object. You can use Shopify’s Liquid template language to personalize emails with custom data or build fully dynamic email templates.

Target Emails with Segments

To help you better target your contacts with emails that are relevant to them, you can create subsets of your mailing list based on contact data like language preferences or tags.

Keila includes a visual segment editor and a powerful segment language for more complex cases.

Read more about using segments in the docs.

Extensibility With a Comprehensive API

Keila offers a comprehensive API to manage contacts and campaigns. This allows you to create integrations with your existing tools and automate your email marketing workflows. For a no-code/low-code option, we currently have a Zapier integration in private beta.

Take a look at the Keila API docs.

No Vendor Lock-in and 100% Open Source

Keila is 100% Open Source with no proprietary premium features. You can become a part of the community by contributing bug reports, translations, or code on GitHub. Take full control of your data with Keila. Our official Docker image is ready for self-hosting.

My team and I have sent hundreds of client newsletters with various tools over the past 20 years. Today, I recommend Keila because it’s a joy to use, has excellent support, it’s open source, and feels much more in line with what’s important to me.
