In the attendee and speaker reports, any potential email deliverability issues reported by the recipient's mail server will be highlighted.
Emails highlighted in Red
Issues highlighted in red indicate that there was a hard bounce (meaning that the email address could not be found) or that the recipient marked one of your emails as spam. When this happens, we will immediately stop sending any emails from this recipient to protect your email reputation.
Emails highlighted in Yellow
Soft bounce – A temporary email delivery failure. For example, the mailbox is full, there are too many connections (also called throttling), or the connection times out. Amazon SES retries soft bounces multiple times. If the email still cannot be delivered, then Amazon SES stops retrying it.
A deliverability email highlighted in yellow indicates what is known as a soft bounce. This is when the recipient's mail server reports back to us that there is a temporary issue with them receiving the email. This could indicate that their inbox is full or that there is a temporary network issue with their mail server. When this happens, we will continue to attempt to send future emails to that recipient.
Once one of those future emails is successfully delivered (as reported by AWS), the previous bounce flag is automatically cleared.
To further clarify, if a transactional email fails to send, we won’t retry that specific email. But if a later email goes through successfully, then all future emails to that address will proceed unless another bounce occurs.
You can filter the attendee list by those who have an email issue under Reports > Attendees. If you hover over the 'Email issue' label, you can see if the issue is a result of a hard bounce or a spam complaint.
If you’re seeing a heightened level of emails flagged in either the attendee report or the email sent report, and if they’re in yellow, then that could mean a deliverability issue.
If you’re using a custom email sender, we highly recommend activating DKIM signatures. Although this is optional, it can significantly improve email deliverability.
Please note that in order to set up your DKIM signatures, your custom email address should be verified first.
If you would like to check what a specific email will look like ahead of time, you can always send yourself a test email. If you were to customize an email template, for example, sending a test email allows you to see the email exactly as it will appear when it's sent to attendees or speakers.
You can do this from your Dashboard by going to Emails. From here, click the three dots next to the template you'd like to send and select Send Test Email.
