In the past several months, I have researched CRM's for small businesses. There are so many to choose from that I became overwhelmed with this task. Doing comparisons from one company to another didn't help , so much information each CRM company  gave, I'd forgotten what I read when I went to the next one, it was daunting and never ending. Finally, what I've done as a process of elimination:  I looked at their pricing menu as a starting point, something In line with my monthly budget. I took the features I was most interested in, selected my top three and then did  a comparison to each. This was the easiest and most efficient way of choosing. 
Most CRM's offer you a thirty day trial period, so I signed up and registered for live demos and took advantage of the companies that offered phone support. Since I am a visual person, having phone support and someone to walk me through was a breeze and helped me decide which one I liked the best, based on the features and customer service.
I held off as much as I could before getting serious in implementing a CRM into my business. But having had the opportunity to try different ones, I  arrived at the conclusion,  to be efficient in business, no matter the size , was the smart thing to do. During my research, I was also contemplating on an email service. I had tried a few of these, but I wasn't keen on having to load emails outside a database.I wanted one shop stop.
