An attendee reports that they did not receive an Invitation e-mail, a Confirmation e-mail, or an E-mail campaign. In most cases this is not a system outage — the e-mail either reached a wrong address, landed in spam, or was never sent at all (a missing language version, an unassigned contact, the wrong attendee status).
Open Check-in or Registration and find the attendee. Check their e-mail address, RSVP status, and preferred language — that narrows the cause.
Wrong e-mail on the attendee — a typo, an outdated company address.
Spam or the Promotions / Updates tab — e-mails are sent from the domain invitation.happenee.com; the attendee may not recognize it.
The campaign did not go out because a language version is missing — if the Campaign is not ready to send dialog appeared when you sent it, no mailing was created and you will not find one on the Mailings tab. The dialog lists the languages that are missing a subject or content.
The Invitation e-mail has not been sent yet — the Invitation e-mail is not automatic; it has to be sent manually (individually or in bulk).
The attendee is not assigned to the event — Invitation e-mails and campaigns only go to assigned contacts.
The attendee's status is Not attending or unsubscribed — the Confirmation e-mail is not sent.
For events with Tickets — the buyer paid, but the attendee has not yet completed the Registration form; the ticket with the QR code is generated only after registration is complete.
Confirmation e-mail after a correction — in Check-in find the attendee, fix the e-mail address, switch the status to Attending, and resend the Confirmation e-mail (the checkbox shown when the status changes).
Incomplete registration on a paid ticket — in Orders expand the specific order and use Notify on the ticket. In bulk: Notify by e-mail → Unregistered above the order list on the right. A link that went out within the last five minutes is not sent again.
Campaign — on a sent campaign, open the Mailings tab, use the Resend campaign to newly assigned panel and the Newly assigned button to reach attendees who were not yet assigned to the event or the group when the mailing started.
Checking a specific address — on the Mailings tab, open E-mails for that mailing. For every recipient you see whether the e-mail was sent, delivered, and opened. Not delivered in the Mailing status chart means a delivery problem (a typo in the address, a full or closed mailbox, a block on the recipient's side) — resending will not fix that, correct the address first.
Campaign stopped by a missing language — switch Content language to the languages the dialog listed, fill in the subject and content, and send the campaign again.
Always fill in e-mail and campaign content in every active language, even when you assume all your attendees read the same one.
For paid events, in Orders check the gap between purchased tickets and completed registrations — the gap is the attendees with an incomplete registration who only need the link resent.
Before any bulk send, always use the Test campaign or Test invitation e-mail action and send to your own address.
Name-based check-in in the attendee app does not exist today — on event day it is practical to send a reminder with the QR code an hour before start, so attendees have the ticket at hand even without app access.
First ask the attendee about the Promotions / Updates / Spam folder and the invitation.happenee.com domain. Only then resend.
With Registration with additional information, the ticket is generated only after the Registration form is completed. Check the status in Orders and resend the link if needed.
