Video Tutorial: Uploading your emails 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.

Once the HTML has been exported, you'll need to manually upload your HTML templates to SendX by pasting your HTML code into a campaign via the Custom HTML import feature, as per their docs here.
