A guest did not receive an invitation. What should I check?

Find the guest on Manage → Guests, or Manage → Invite in an app version before 1.3. Check that their email address is correct and that an invitation was actually sent. Adding or importing a guest alone sends nothing. On the website, a guest who has never been sent one and hasn't answered is under Invitation not sent, under Filter. A guest who answered without one, or whose answer you recorded, isn't sent one by the bulk send; open them and press Send the invitation if they want the link by email.

On the website, guests whose invitation can't reach them are under Needs a look, and Invitation, when you open one, says why: Email bounced when the guest's mail server turned it away, Couldn't be delivered when it never left, or Unsubscribed when the guest opted out of this event's email. An unsubscribed guest is left out of the send. A guest you added without an email isn't under Needs a look: the list says No email beside them, and the link you send them yourself is their invitation.

Ask the guest to check spam and other inbox folders. If sending is paused, read the allowance message before trying again. An address that bounced or unsubscribed may not receive another bulk message.

A guest whose invitation bounced or couldn't be delivered shows Fix the address instead of a resend. Enter the right address and choose Save and send: the new address is saved and the invitation goes to it. The address that failed stays blocked. An address already on your list is refused.

If you don't have a better address, agree another way to share the guest page. Keep Who can come in mind: a shared link does not bypass the guest list.
