The Value of WhatsApp Business API

- Verified sender profiles for brand authenticity

When powered by MSG91, the WhatsApp Business API becomes part of a broader communication suite that includes SMS, email, RCS, and voice making omnichannel engagement simple and streamlined.
Why Integrate WhatsApp with CRM and Marketing Automation?
Integrating WhatsApp with your CRM (like Salesforce, Zoho, HubSpot) and marketing automation tools (like Mailchimp, ActiveCampaign, Marketo) ensures that customer conversations are not siloed, but part of a unified journey.

Example:

- Personalized Campaigns Based on CRM Data
Send promotional WhatsApp messages based on customer segments:

Example:
