Having the ability to create email lists and send mail to entire list at once in Sales CRM would help us tremendously. I am aware this is possible in the marketing side, but it creates issues as it forces interdepartment dependencies that complicates the workflow.
Our specific purpose would be to send updates to existing clients as handling communications through Hubspot would be an integral solution. It is also worth saying that forcing the use of the marketing CRM for this type of communication becomes more costly given the limited # of contacts per tier allowable in the marketing CRM.
I do think the contact pricing for marketing CRM needs to be revamped as it is cost prohibitive for my retail service business that would use it for newsletters to exisitng clients, quite different from the inbound system Hubspot marketing is modeled for. See my other post for that here
