Custom HTML Blocks

Custom HTML blocks let you add any HTML content to your signature template.

Adding Custom HTML

In the Visual Editor, click Add Custom Block to insert a custom HTML section. You can write or paste any HTML code into this block.

Common Uses

• Legal disclaimers
• Custom promotional content
• Embedded call-to-action buttons
• Additional contact information layouts

Best Practices

Use table-based layouts for custom HTML blocks to ensure compatibility across email clients. Avoid <div> elements and CSS flexbox/grid.
