Scenario

When creating your signature template, you notice a pop-up appear in the preview window advising you of a 10,000 character limit.

For example:



 

Reason

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.

Below is a comparison of a signature and its code:

CAUTION! Some of these methods may not work on their own, and you may need to combine multiple methods.
Shorten links

There are many ways you can shorten a URL within an email signature, and it is suggested to do so where possible. An example of this is the Google Maps links; they can be extremely long and will add to the character limit.

There are many free tools available that can shorten links to a much more manageable size.

CAUTION! Depending on the recipient's security, using the various tools for this may cause issues with SPAM, and it is advised to use it with caution. We recommend using shorter links in your signature without using the tools. An example of this would be to point a map location to your contact us page on your website where the map's location already exists.
Combine elements in your design

One way to reduce the amount of HTML the email signatures generate is to simplify the signature.

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.

Use Tables to create the signature layout

Sometimes, using tables to separate your information is better - this creates less HTML than grouping elements.

After

Reduce the amount of data being displayed

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.

Add content through Campaigns or Disclaimers

Our Campaigns and Disclaimers features add extra content that lies outside of the signature template, reducing the character count. Disclaimers applies plain text content, useful for legal disclaimers, and Campaigns applies limited-time image content.

NOTE: Disclaimers cannot be used for Client Side deployment in Gmail.
