If your customers are not getting offer emails, the most common reason is that the messages are landing in their junk or spam folders. Please ask your customers to check those folders first.
Email providers often use filters that may accidentally treat these notifications as spam. This is especially true if your store uses a custom email domain for outgoing messages.
If your customers still do not see the emails after checking their spam and junk folders, reach out to our support team. We are happy to help you look into the issue.
