Loxo's signature editor supports standard text formatting and simple layouts. If you'd like to use a more advanced signature design - including logos, social icons, multi-column layouts, banners or custom styling - we recommend creating the signature externally and then importing the HTML into our platform.
Recommended Option: Use a Signature Generator
The easiest way to create a professional HTML signature is with a signature builder tool.

Proven Practices for Reliable Display
Email clients (especially Outlook) can be very strict about HTML formatting. Following these guidelines helps your signature display correctly.
Use Tables for Layout
Most email clients do not fully support modern web layouts like Flexbox or CSS Grid.
Recommended:
Table-based layouts
Simple spacing
Fixed-width sections
Avoid:
Flexbox
CSS Grid
Complex positioning
Use Inline CSS Only
Many email clients remove embedded stylesheets.
Recommended:
<td style="font-family: Arial; color: #333333;">
Avoid:
<style>
.signature { color: #333333; }
</style>
Use Publicly Hosted Images
Images must be accessible through a public URL.
Recommended:
<img src="https://yourcompany.com/logo.png">
Avoid:
Local computer file paths
Private Google Drive links
Temporary file-sharing links
Keep Designs Simple
Simple signatures perform best across:
Outlook
Gmail
Apple Mail
Mobile email apps
Common, Universal Signature Issues
My signature looks different in Outlook
Outlook has limited HTML and CSS support. Simplifying layouts and using tables usually resolves this.
My images are broken
Your image URL may not be publicly accessible. If you uploaded from your computer or copy/pasted from an image file, this is the typical reason behind images not displaying. The image must come from a publicly accessible image.
My spacing changed after saving
Some email clients automatically modify HTML formatting. Using table-based layouts and inline styling helps maintain consistency.
Unsupported Elements
The following elements are not supported:
JavaScript
Embedded forms
