Integrate your tech stack
Developing emails outside of your ESP has never been easier.
Import directly from your ESP
Parcel works complimentary with any ESP. Meaning you can import code from Parcel into your ESP, or import from your ESP into Parcel. We're the industry-leading code editor, allowing you to code, iterate, and build emails faster than ever.

Create blocks of code where when you update once, it is reflected across all emails.
Clean up unused CSS, auto-append URL parameters, or prettify your source code.
As you type, the editor will suggest valid tags. Continue typing, or use the arrow keys to select the correct suggestion. Closing tabs are auto added.
Live code with others in one file in real time. No need to save, and pass the file back and forth!
Content validation
Email foundations, simplified
All the email creation features that your ESP email builder doesn’t have.
