Troubleshooting: Team Invite Not Received

If a team member says they never received their Shelf workspace invitation, run through these checks.

1. Check the spam / junk folder

Shelf invitations come from noreply@shelf.nu (or your configured sender on self-hosted). Many corporate email filters flag automated invitations. Ask the recipient to check their spam folder and mark Shelf as safe.

2. Verify the email address

A typo in the email is the most common cause. Go to Settings → Team → Users → Pending Invites and confirm the address matches exactly — watch for:

Extra spaces before or after the address
.com vs .co vs .nu mixups
Autocorrect changing the domain

If the address is wrong, cancel the invite and re-send to the correct one.

3. The link opens but says "Wrong user"

This is a different problem from the email not arriving, and it is fixed.

An invite created by the CSV user import used to keep the capital letters of the address as typed, for example First.Last@company.com. The person's own account email is stored in lower case, so opening the invite link while signed in compared the two, found them different, and refused with "Wrong user". Opening it signed out gave an error page rather than joining the workspace, if they already had an account.

Shelf now matches an invite email without regard to letter case, everywhere it is compared. Invites already sitting in your workspace with capital letters work as they are — there is nothing to re-send and nothing to clean up. If the person is still stuck, they are hitting something else on this list.

"Wrong user" can also be genuine. If the person is signed in to Shelf with a different address from the one you invited, the message is correct and the fix is theirs: sign out, then open the link again, or sign in with the invited address.

4. Check if they already have an account

If the recipient already has a Shelf account under a different email, the invite may have landed in that account's workspace list — but they're logging in with the other email. Ask them to try logging in with the invited address.

5. Re-send the invitation

From Settings → Team → Users → Pending Invites, you can re-send. A re-send issues a fresh link and closes every earlier invite for that person in this workspace, so only the newest link works. Tell the recipient to use the latest email; an older one will no longer let them in. Earlier invites are matched without regard to letter case, so a variant stored with capitals is closed too.

6. Corporate email filters (IT-managed inboxes)

Some organizations block emails from unknown senders or require domain whitelisting. If the recipient's IT team manages their inbox:

Ask IT to whitelist shelf.nu (and supabase.co for self-hosted instances using Supabase email)
Alternatively, the recipient can sign up directly at app.shelf.nu/join using the invited email address — Shelf will auto-connect them to the workspace
