No Postiz account found for this email

Error message

No Postiz account found for this email

What it means

Thrown as HTTP 400 when inviting a team member by email and getUsersByEmail returns no user accounts. Postiz only allows inviting existing users — there is no invite-by-email signup flow here.

Solutions

1. Have the collaborator create a Postiz account first, then retry the invite
2. Double-check the email spelling and trim whitespace
3. Confirm you're both on the same Postiz instance

const users = await lookupUsersByEmail(email);
if (!users.length) { showInviteBlockedMessage(); return; }

const userExists = (users: unknown[]): users is [User] => users.length === 1;

try { await addTeamMember(orgId, email); } catch (e) { if (/No Postiz account/.test(e.message)) { showNotice('User must sign up first'); return; } throw e; }

When it happens

Trigger: Calling addTeamMemberByEmail with an email that has never registered on this Postiz instance (wrong server, typo, or unregistered collaborator).

Common situations: Trying to invite someone who hasn't signed up yet; typo in the email; user registered on a different deployment (self-hosted vs cloud); case/whitespace differences if lookup is exact-match.
