Email signatures have a size limit of 10,000 characters in the HTML. The plugin will warn you after exporting your email signature if its over the size limit. To avoid this you can use some of the Signature starter components under the Footer tab in the Emailify plugin.
Unfortunately, any responsive mobile overrides won't be rendered for any "HTML Email Signature" exports, as any CSS style tags and @media queries are stripped out by email clients (therefore, it's also not included in the code export), so it's worth trying to strike a balance in the original design that looks nice across both desktop and mobile widths.
Video Tutorial: Design and export HTML Email Signatures from Figma
This video walks through how to design and export production-ready, responsive HTML email from Figma using the Emailify plugin.
Export your HTML signature from Emailify
In the Emailify plugin, click on the Export HTML button to open the export panel, select the HTML Email Signature option from the dropdown list, then click the Export to HTML Signature button to start exporting the emails you've selected from Figma to HTML.
After Emailify has finished processing your email(s), you'll be shown a confirmation message; you can download your .zip file to your computer by clicking the Download your .zip file button, then you can unzip the .zip to see your exported files.
Copy your HTML email signature to the clipboard
After you've exported your HTML email signature from Emailify and unzipped the .zip file, you can open the preview-and-install.html file in your Google Chrome web browser (as other browsers like Safari may have issues) and then click the Copy HTML Signature button on the preview page, which will automatically copy the contents of your HTML signature to your clipboard.
Some email clients may require the "raw" HTML code, so if that's the case, you can click the Copy HTML Signature (Raw Code) button in the preview-and-install.html file to copy the selection as raw HTML to your clipboard that way instead.
Once you've copied the HTML to your clipboard, you can follow the instructions below (taken from the excellent guides provided by SignatureHound) to install the signature in your email client.
How to install your HTML email signature in Outlook 2019 (Windows)
Outlook infamously uses the Microsoft Word rendering engine for email which will cause differences to your signature preview. Spacing and font sizing will appear slightly differently, images are often squished, and underlines will be added to your links. For many of your recipients these links will appear with a blue underline, irrespective of the color you set for them.
If you really care about your email signature being "pixel perfect" then we recommend using a different email client that uses a HTML rendering engine such as Outlook.com.
With Outlook open, click the New Email button to bring up the email composer.
Click Signature in the message toolbar and then the Signatures option to open the Signature Settings modal.
Select the existing signature you'd like to edit or click New to create one.
Copy and paste your signature into the signature editor.
Click OK to exit the Signature Settings modal.
Now under the Signature option in the message toolbar you should see your signature. From this dropdown click your signature to insert it into the email body.
