The base design components that come included with the Emailify plugin have been pre-tested using Litmus to ensure they look great across all popular desktop (including Outlook) and mobile email clients.

However, it's always worth doing a test of your own emails using a service like Mailgun Inspect, Litmus, or Email on Acid, just to ensure they're looking good before you send them out.

You can also send the exported HTML to inboxes you can access using a service like htmltest.email. See Sending manual HTML email inbox tests for the complete workflow and its limitations.

Using the Mailgun Inspect integration ​

Emailify includes a dedicated Mailgun Inspect integration that uploads the generated HTML directly from Figma for preview testing across the email clients and devices available to your Mailgun account.

See Testing HTML emails with Mailgun Inspect for setup and upload instructions.

Using the Email on Acid integration ​

Beginning in June 2026, current Email on Acid subscription customers will start transitioning to Mailgun Inspect.

This video walks through how to upload HTML email tests from the Figma Emailify plugin to Email on Acid.

Emailify includes a built-in integration with Email on Acid, which lets you upload HTML email tests directly from the Figma plugin directly into your Email on Acid projects.

In the Emailify export panel, select the Email on Acid option from the dropdown list, then paste in a valid Email on Acid API key, which can be generated from your Email on Acid account page, and then paste in your Email on Acid account password (the one you login to the website with) into the second text input field in the Emailify export options.

When you're ready, click the Upload To Email on Acid button to start exporting the emails you've selected from Figma to HTML, and have them automatically be uploaded to your Email on Acid projects.
