Components vs. Partials

Components allow you to work significantly faster and spend less time repeating code. They are similar to Litmus's partials but provide an unmatched level of flexibility and power.

Partials are static - they can only be used for completely unchanging blocks like footers and logos. Otherwise, you must use snippets and manually update every email when you need to change something about the snippet code.

Components are dynamic - allowing you to pass in content, and options, use logic and even fetch remote data. With components, you can create an entire design system that you can update at any time without additional effort other than the code update itself. With each component, you are creating a single source of truth for your design system.

Optimize your code

Parcel automates many of the manual steps email developers have to do today for optimization and code cleanup. With just a few toggles you can keep your emails below the clipping limit, remove unused code, and support GANGA.

Validation/Pre-send Checklist

An important step to make sure your email is ready to send is to verify your code is valid, accessible, your links and images work, and that you aren't sending content that will be flagged as spam.

Parcel brings these validation steps right next to your editor, so it is easy to test and validate your work.
