CRM alternative to “HowNow”

Looking for an alternative for HowNow from Business Fitness. https://www.businessfitness.com.au/solutions/hownow/

CRM that can store files of clients, also have integration with Outlook so that the emails with the clients can be saved. Also, have the feature to store all of the details of the clients as well. Currently, we are using HowNow for file management and APS for client information management. I am looking for a single software that can handle both these tasks.

​

Thanks
