What it is

Email-templates is a tool for developers to design, test, and deploy custom HTML email templates. It streamlines the process of creating visually appealing emails that work across different email clients.

Email-templates stands out as an open-source, self-hosted solution that simplifies the process of creating and testing HTML email templates directly within a developer's workflow.

When it fits — and when it doesn’t

A good fit for

  • Developers who need to create and test email templates quickly without leaving their coding environment.

  • Marketing teams looking for a tool that ensures consistent design across different email clients.

Look elsewhere if

  • Teams requiring real-time collaboration features on template creation.

  • Projects needing extensive customization beyond what the library provides out-of-the-box.

Known weaknesses

Each one links to the public issue, changelog or docs page it came from, where we have one.

  1. 01

    Limited language support

    Primary support is for JavaScript, which can be a limitation for teams using other languages.

  2. 02

    Poor documentation for advanced use cases

    Documentation lacks detailed guides on complex email design and troubleshooting common issues across various email clients.

  3. 03

    Performance issues with large templates or high volume emails

    Rendering of large HTML templates can be slow, impacting the development workflow and deployment times for high-volume email campaigns.

  4. 04

    Small community and limited third-party integrations

    The open-source nature means there is a smaller user base contributing to the project, leading to fewer plugins and integration options compared to more popular tools.

What it does well

  • Template creation and previewing in a single environment

  • Compatibility with major email clients

  • Customizable templates for various use cases
