Video Tutorial: Uploading your emails to SendX
This video tutorial is a complete step-by-step guide showing you how to upload HTML emails from the Figma Emailify plugin to SendX.
In the Emailify export panel, select the SendX option from the dropdown list, when you're ready, click the Export For SendX button to start exporting the emails you've selected from Figma to HTML.
