HVEL - Attest Approved Email Layer

Add a visible trust signal to your emails. Verify as Human, AI Assisted, or Automated.

Account-Specific Email Identity Verification: - Free Plan: Stamp injection is locked strictly to the specific email ID used to log in to the HVEL extension (e.g. user@gmail.com). Composing from any unlinked email ID automatically blocks stamp injection and alerts the user. - Professional Plan: Users can link up to 4 additional verified email alias IDs to their primary account, allowing authorized stamp injection across multiple linked email addresses.
