Hello Sandra,

Yes, this is a common behavior in Odoo. While it does support HTML signatures, it tends to sanitize or simplify the HTML/CSS, which can cause formatting issues especially with complex layouts, external styles, or unsupported tags.

To improve the result, you can try:

• Using inline CSS only (avoid external styles or <style> tags)
• Keeping the HTML structure simple (tables work better than div-based layouts)
• Avoiding advanced styling (like floats, positioning, or scripts)

If the issue persists, slight adjustments to the HTML code are usually needed to make it compatible with Odoo’s editor.

Hope this works for you! If you need any help implementing this or want a more optimized approach, feel free to reach out for further discussion
