Customer feedback is what helps you grow. You can hear your customers only when you have facilitated them an easy way to reach out to you. Such an avenue should be easily accessible to customers, and easy to set up and use by salespersons like you. SMS is one such medium. SMS has an amazing open rate and almost everyone has a mobile phone, making it very accessible to everybody. To ease things at your end, extensions like Nexmo come into the picture.
The Nexmo extension for Zoho CRM helps salespeople send and receive messages from their Zoho CRM dashboard itself, thus helping make messages more contextual, while saving time. You can create custom messages, thus tailoring bulk messages for certain groups or contacts. Responses received from customers via SMS are also stored in the leads/contacts' related list enabling you to follow the entire thread of conversation.
Taking it a step ahead, you can also create interactive voice responses(IVR) to interact with your customers and get their results too, in that lead/contact’s record page, for further analysis. Apart from SMS, the Nexmo extension also allows you to send voice messages too.
You can install the Nexmo extension from Zoho Marketplace. You can read in detail about how this extension works inside Zoho CRM in this help document.
