How often are email signatures updated?
Summary:Trustindex email signatures are updated daily to show your review score. However, email clients like Gmail or Outlook cache images, so updates may take up to two weeks to appear in your emails.
Daily updates in Trustindex
All email signatures are refreshed within Trustindex every day. This ensures that your current review score is always available for display.
Why updates may take longer in email clients
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
Once the cache updates, your recipients will see the latest version automatically.
Tips
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
