Undelivered Emails
Any emails that fail to be delivered by the system will be logged inside the Undelivered Emails section. You can find this section by going to:
Settings > General > Undelivered Emails
Each row contains the user's email address, the email's subject, and the date the email was sent.
There are several reasons why your email(s) have bounced into this section:

The user's email address is incorrect or invalid. Most commonly, emails are marked as undelivered because the user's email address is spelled incorrectly or the user's email address has been modified or deleted. It is best to confirm the
The user's mailbox is full. If the user's inbox has run out of storage space, your emails will bounce until enough space has been cleared (emails archived or deleted) for the email to be received.
The user's email server is down or overloaded. If the receiving user's email server is unavailable for any reason (it has crashed, is under maintenance, or cannot be found at all) any emails sent during this period will bounce.
Your email address has been blocked. Emails can bounce if the email address or server has filtering rules in place, or if the user has blocked your address from their account. These issues can be resolved by contacting the user and asking them to update any filters or blocked contacts for their account.
If an email was marked as undelivered, it will not be resent by the system automatically. You must trigger or resend the email notification again to reattempt the delivery.
Why are my emails going to Spam?
There are many different reasons why emails end up in someone's spam folder. This is very common, and when you have a large list, at least one email will likely end up in the spam folder. Sending emails is all about managing reputation and following best practices that are constantly evolving and becoming stronger.
It is highly recommended to follow best practices when sending emails, especially large promotional ones. Although BookingKoala may permit certain actions when sending an email, that doesn't mean it's a good practice. For example, we allow a sender email to be either a personal email or a business email, and best practice is to use a business email. Another example may be URL shorteners. Although BookingKoala may allow you to include a long URL, it may be flagged, and all your promotional emails may end up in the spam folder. A third example would be emailing someone daily or multiple times per day. Depending on the content of your emails, they may be flagged as spam, and all your emails may end up in the spam folder.
To minimize emails going into the spam folder, please learn more about sender reputation and email deliverability by visiting Google and YouTube. Keep in mind not all email hosts follow the same rules. Google may have different rules regarding what they like, dislike, and flag versus Yahoo or Microsoft.
Also, keep in mind that if one day your emails are all being delivered, that doesn't mean they will continue being delivered the following week. For example, if your reputation does go down because a few customers marked your emails as spam or a system detected that your promotional emails are spam, that may cause all future emails to be directed to the spam folder. Treat your sender's email and reputation with care to avoid hurting your score.
