Yes! A CRM will allow you to quickly and easily segment your leads or customers, based on a number of criteria which you can define. By using Zoho CRM you can reach the right people with the right information. Your team can create campaign email templates which pull customer-specific data from the CRM into the email body: name, salutation, address, product name etc, giving you a high degree of personalisation. In addition, Zoho CRM allows you to have unsubscribe links ('opt outs'), allowing you to adhere to anti spamming laws and you can also set up auto responders for contacts who may 'subscribe' to your newsletter via a simple web form and the so-called 'web-to'contact' feature, helping you to maintain a fairly robust email marketing process for your business.
