If you’re looking for a customer relationship management system that integrates well with your email inbox, the above features can significantly improve your productivity.
To establish this ranking, I reviewed a list of about 600 possible CRMs in order to make a pre-selection. I then directly tested each of the 7 selected CRMs and sought to find out which of them offered which functionality, which I detail below.
It’s important to keep the bigger croatia phone number data picture in mind when comparing CRMs, though, because you need to make sure your team will actually use that CRM. Getting a CRM that no one uses is pretty pointless.
For this reason, I’ve included each CRM’s current score Customer Relationship on G2 so you can get a better idea of how each CRM stacks up. It breaks down as follows:
- Ease of use
- Ease of installation
- Meets the requirements
- Quality of support
- Ease of doing business with
- Ease of administration
And to top it all off, I’ve also run contests and giveaways incorporated the rating each CRM’s mobile app gets on Google Play. So the app isn’t just useful for your email inbox, it’s also useful for your phone!
I then took the average of the email integration feature score, the average G2 review score, and the Google Play score Customer Relationship for the mobile app, to calculate… the final score!
