Why is there a blue box around my logo or avatar?
This usually happens in email clients where you copy and paste your signature into the client's settings — like Gmail or Apple Mail. It's caused by how the signature was copied, not a problem with the signature itself.
How do I fix it?
Instead of copying your signature directly from the signature page, click Open in new tab first, then copy your signature from that new tab. This resolves the blue box in most cases.
