First of all, the alerts that we display are in no way blocking the use of your signatures / campaigns. They are only recommendations on our part.

  • First case :

On a cell phone the recommendation is 300px wide for a signature.

This means that the signature may be cut off and/or unreadable when the email is read from a cell phone screen (if it is wider than the 300px to try to fit the screen size).

  • Second case :

This alert only applies to signatures deployed with the push API for Gmail.

If you exceed the 10,000 character limit, Gmail may display an incomplete signature or nothing at all.

This is because it limits the number of characters contained in the code of a signature to 10k. These are not only the contact information you can see but also the code of images, links, generated HTML code, etc.
