You can refer to CRM:0082139 for an example .csv file and an explanation of how this feature would have benefited me in a real situation.
Occasionally, I need to send an email to a group of managers with information about their employees. Sometimes, a manager has more than one employee that is being affected by a new program, so the manager is included multiple times in the .csv file that I am importing to PoliteMail.
Unfortunately, PoliteMail automatically removes duplicate email addresses from a .csv file upon import. As a result, I can't use PoliteMail to send these emails, we need to go back to mail merge technology.
It would be extraordinarily helpful if PoliteMail would provide an option during .csv file import to "keep duplicate email addresses" in the imported file.
Most of our customer base wants to avoid duplicate contacts. I wonder if you might be able to use Custom Fields for resolving this issue. If you do want to send multiple messages, this might be a suitable workaround using Plus Addressing.
Thank you for submitting your idea to PoliteMail. I have forwarded it to our Development team for review.
