Feature comparison
Frequently asked questions
What is the main difference between Zenkai and MailerLite?
The main difference is that Zenkai is managed and fully managed, while MailerLite is proprietary SaaS. Zenkai uses pay-per-email pricing versus MailerLite's pay-per-subscriber model. Both are developer-friendly, but Zenkai is API-first with full code transparency, while MailerLite focuses more on visual email builders with good API support.
Is Zenkai more expensive than MailerLite?
It depends on your usage pattern. MailerLite charges based on subscriber count (e.g., $10/month for 1,000 subscribers), while Zenkai charges per email sent. If you have a large subscriber list but send infrequently, Zenkai is typically cheaper. If you email your entire list frequently, costs are similar. The key difference is predictability: Zenkai only charges for actual usage.
Can I use Zenkai Zenkai unlike MailerLite?
Yes. Zenkai is managed (AGPL-3.0) and can be managed using Docker. This gives you full control over your data, infrastructure costs, and compliance requirements. MailerLite is cloud-only with no managed operation option. managed operation is ideal for privacy-sensitive use cases or cost optimization at scale.
Does Zenkai have a drag-and-drop builder like MailerLite?
Zenkai has a basic email editor, but most users manage templates using HTML/code for full control, version control, and reusability. MailerLite excels at visual drag-and-drop building for non-technical users. If you're a developer who prefers code-based templates, Zenkai is better. If you need rich visual builders for marketers, MailerLite is better.
How does Zenkai's API compare to MailerLite?
Both have modern REST APIs, but Zenkai's API is designed with developers as the primary user. Zenkai prioritizes API-first workflows, making it easier to integrate email into your application. MailerLite has a good API but is built UI-first with API as secondary. For programmatic email sending and automation, Zenkai offers a superior developer experience.
