A lot of photographers use email to send photographs but if sending photos to several picture desks at once (ie multiple recipients), it increases the chance of the email being seen as spam.
It would be good to have a feature where i could send an email with multiple recipients but each recipient would receive a separate email. It currently takes too long to send each recipient an email separately. Also to be able to use PM as the email client would be nice instead of having to open outlook, i could just put my email servers details in the PM preferences.
Lastly the ability to track sent email would be great.
