When creating your signature template, you notice a pop-up appear in the preview window advising you of a 10,000 character limit.
The signature is synchronized to Gmail as HTML code using Google API, which has a 10,000 character limit.
As text formatting, image styles, tables and hyperlinks are all stored within the HTML, this can add a significant amount of characters to the signature size.

There are many free tools available that can shorten links to a much more manageable size.
Check if it's possible to combine information into one text box, such as an email address and web address or even a physical address?
You may not be able to combine some information, such as dynamic information.
Sometimes, using tables to separate your information is better - this creates less HTML than grouping elements.
Re-evaluate the information you are putting into your signature template.
For example, do you really need to display an email address? Can you remove the Website URL and simply have this as a clickable link on your logo or social media icon?
One way to reduce data in your signature is to use a QR code to link recipients to important data outside of the signature, such as with a personalized vCard for contact details. For more information, see Working with the QR codes signature element.
Legal Disclaimers in email signatures are typically required by law; however, the information displayed can vary. You can simply add this in by creating a link for the end-user to click on instead.
Check with your Legal team beforehand to ensure there is no legal requirement for you to have this displayed in your emails.
