HeySummit shows recipient delivery issues in Registration & Attendees > Attendees and Content & Schedule > Presenters. Use Email & SMS > Delivery Logs > Email for individual messages.
Red email issues
An attendee's red Email issue can indicate a hard bounce, complaint or rejection. A hard bounce usually means a permanent delivery failure; a complaint means the email was reported as spam. HeySummit excludes blocked recipients from future event email attempts to protect sending reputation. Presenters show delivery issues in their Issues summary.
Yellow email issues
A yellow Potential email issue means a soft bounce or temporary delivery problem. Examples include a full inbox or a temporarily unavailable mail server. Amazon SES can retry before reporting a final bounce. A soft-bounce flag alone does not block later HeySummit email attempts, but it does not guarantee successful delivery.
Find the affected records
In Registration & Attendees > Attendees, open Filter records and use Has Email Issues?. Hover over a status for its explanation. The attendee tooltip can describe a general delivery block rather than identify the exact cause.
For recent messages, open Email & SMS > Delivery Logs > Email. Search by email or subject, or open Filter records and select a Status. The list covers the last 14 days. Failed concerns a specific email that could not be sent; it is not the same as a recipient-level delivery block.
The Delivered label means the message was sent without a recorded bounce in this view. It does not prove that it reached the inbox or that the recipient read it.
Check sender setup and test delivery
For a custom sender, complete its email-address verification and domain-authentication checks under Email & SMS > Emails > Manage senders in the toolbar menu. DKIM alone is not the whole readiness check; the configured sending domain must also pass the required mail-from and DMARC checks.
To send a copy to your own dashboard-user address, open the email row's Actions > Send test. Use previewing for a no-send content check. A test send does not override an account-wide sending pause.
