Question: In the Preview panel, please add the list of attachments. This would help me avoid sending the wrong receipt to a customer, which I have done an alarming number of times.
Answer: MaxBulk Mailer 8.6.2 will include that feature.
Indeed, all the attachments will be visible in the header part of the message so you can check them before the delivery of your message. MaxBulk Mailer will even show errors if any. That feature has been added because MaxBulk Mailer is able to send custom attachments.
You can try the beta version whenever you want. It is available here:
