BEST CRM tool for RVMs, Emails and SMSs

[Rajan Nanda]

Hello team! 

Newbie here! Just trying to set up systems right before I get out there. What is the best CRM tool that will send automated Texts, Emails and RVMs? (Use case is -  while i am away and I could not talk to sellers or after my initial conversation - this CRM tool sends constant communication on my behalf).

Thanks for your help in advance.
