Hi! New user to the email side of this and id love some suggestions. Few things that have been easier on other services and id love for them to be easier here too. Anyone have any tips on how to navigate the below. Tagging isnt fun. What would it take to make this easier? Sorting customer could use some more fields. Like recent email activity. Like to be able to send emails just to the people who have opened the last email sent. Like to be able to unsubscibe multiple people at one time. Unable to edit/correct customer profiles information??? Thanks in advance! Rosie
