If you haven't received your verification or invitation email, don't worry — this is one of the most common issues, and it's usually easy to fix.
1. Check your spam or junk folder
The invitation email is sent from Label Studio Enterprise and has a tendency to land in spam or junk folders rather than your inbox. Search for "Label Studio Enterprise" across all your mail folders.
If you find it there, mark it as "Not Spam" so future emails — payment notifications, project invitations — come through without issues.
2. Confirm you signed up with the right address
Double-check that the email you're monitoring is the one you used to sign up. If you signed up under the wrong email, see I signed up under the wrong email or joined the wrong organization.
3. Wait a few minutes and search again
Email delivery can occasionally be delayed. Give it 10–15 minutes, then search your mailbox (including all folders) for "humansignal" or "Label Studio."
Still nothing?
Contact us at contractorsupport@humansignal.com or submit a ticket from an email address you can access, and include the address you signed up with. We can re-send the verification email or correct the address on your account.
