Limitations are added to the signature template to keep the signature as small, in file size, as possible.
You cannot control the limitations, but if they are causing an issue, then we can request this change from the Exclaimer Development team.
If you want another opinion on how you can simplify your signature, then please contact the Exclaimer Template Design team
(just as an idea - can you split the template into smaller ones and stack them using server-side?)
The following table lists all the limitations within Exclaimer Cloud for signature templates:
| Image file size | 150KB |
| Custom font file size | 1MB |
| Elements in one signature | 250 |
| Images in a signature (at one time) | 50 |
| Child elements in one container (such as table, table cell) | 20 |
