It depends what you mean by email drip campaigns. If you are talking about automated emails that go out over a period of time, you can set that up inside of SalesScripter.
But if you are talking about very robust email marketing campaigns in terms of designing creative email templates and a email drip that continues to go for a long period of time, you might need some of the functionality of a system like MailChimp.
If you do that with MailChimp, you basically do that separate from SalesScripter. But what you can do is integrate your MailChimp account with your SalesScripter account so that your email open and click data can be sent from your email campaigns in MailChimp to your CRM database in SalesScripter.
The reason why you would want that data in SalesScripter is that data is extremely valuable and it is actually difficult to view this data and take action on it inside of MailChimp. SalesScripter will take that data and give Quality Points to those contacts and that will make it easy for you to see what contacts you need to be calling and trying to meet with.
