A few quick things to check for Prefect Cloud invites: Where invites show up - In Prefect Cloud, pending invites are managed from your organization/workspace member settings, so first confirm the invite is still listed as pending and hasn’t already expired or been accepted under another login. Common reasons the email never arrives - Spam/junk/quarantine filters - Company mail security blocking automated emails - The recipient previously signed up with a different auth method or email alias - The invite may need to be canceled and re-sent What you can try now 1. Remove/cancel the pending invite 2. Send a fresh invite 3. Ask the recipient to check spam/junk and any email security quarantine 4. If they use Google/Microsoft SSO, have them try logging into Prefect Cloud directly to see whether access is already available or whether they can authenticate with the invited address If it still doesn’t arrive, this likely needs human help from the Prefect team. The best path is: - prefect.io/contact If you want, I can also help you verify exactly where to check pending invites in Prefect Cloud and what role/seat behavior to expect when re-inviting.
