Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
Primary support is for JavaScript, which can be a limitation for teams using other languages.
Documentation lacks detailed guides on complex email design and troubleshooting common issues across various email clients.
Rendering of large HTML templates can be slow, impacting the development workflow and deployment times for high-volume email campaigns.
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.
