RR Media, a WhatsApp, SMS and voice marketing agency based in Liluah, Howrah, says it has seen a steady rise in WhatsApp Business API and bulk SMS adoption among small and mid-sized businesses across Kolkata and the wider West Bengal region over the past year.

The agency attributes the shift to businesses moving away from traditional print and local cable advertising toward direct, measurable messaging channels that reach customers on platforms they already use daily.

Retailers, clinics, coaching centers and real estate agents across Kolkata and Howrah are asking for WhatsApp catalogs, appointment reminders and order updates instead of newspaper ads, said a company representative. It's cheaper, it's trackable, and customers respond to it because it lands on WhatsApp, not in a pile of mail.

RR Media works with businesses across Kolkata, Howrah, and other parts of West Bengal, offering WhatsApp Business API onboarding, bulk SMS campaigns, and automated voice broadcasts, along with support for Meta verification and template approval for businesses new to WhatsApp marketing.
