Using WhatsApp

Now that you have signed up for WhatsApp with your Twilio number, let us see what messages you can send your customers. 
Currently, you can:

  • Type and send individual text messages. (Only after receiving the messages from the customer.)
  • Send textual and image content. You need to get approval from WhatsApp before using media templates.
  • Use standard message templates, approved by WhatsApp to communicate with your customers. In some cases, you can create standard message templates. You can use these templates for different customers and avoid typing individual messages.
  • Once the customer replies to the sent message within 24hrs, you can reply with messages of your own.

Some examples of WhatsApp messages are:

  1. Do you have a new product line you want to talk about? Send a teaser using a WhatsApp message to your customers.
  2. Want to send a quotation to a customer? Send them a notification and attach the quote as a PDF along with a message.
  3. Is it that time of the year again? Send Season's Greetings and New Year Wishes to all your customers.

Note: Standard message templates from Twilio need to be approved by WhatsApp. 

Creating and Setting up Message Templates

Tired of typing and sending standard messages like season's greetings over and over again? You can avoid this hassle by creating standard message templates for your WhatsApp messages.

For example, your company has developed a new product line of paints that reflect changing seasons, and you want to share it with your customers. What if your customer list is enormous, and they want to see the catalog? Well, not to worry, you can use Vtiger CRM's WhatsApp Integration module to send your message.

Just create a standard message that will include a salutation, add the message, and attach the relevant catalog along with your message. Voila, you will send your contacts the new catalog in a jiffy.

Creating and setting up standard message templates is a two-step process.

  • First, create a standard message template on your Twilio console and get it approved by WhatsApp to use from your CRM.
