Summary:All email signatures are refreshed within Trustindex every day. This ensures that your current review score is always available for display.
Email software such as Gmail, Outlook, and others cache the signature images when they are first added. This means:
The cached version of the signature may show older review score statistics
Updates cannot be forced or accelerated
It may take up to two weeks for the newest signature to appear in your emails
Avoid manually re-adding the signature repeatedly; it doesn’t speed up the cache
Be patient—your signature will update automatically once the email client refreshes its cache
