The integration with our CRM is very easy for us as we've used many different platforms in previous jobs. This has been my favorite so far! It's such an amazing tool that I wish they had this at all other companies where I work now. There really isn't much downside here - if there was any dislike about something then it would be the fact that some people are not familiar enough yet with how powerful this software can truly become over time. If you're looking into getting started using sendsquared but aren't sure which features will fit best, try out their demo account first. They have SO MANY options within each feature area that even experienced marketers like me don't know everything right off hand. After doing research online to find great tools/software we decided on send squared because it seemed most advanced and also offered free trial before purchase option. We realized after trying both Aweber & MailChimp that those two were too basic.
