Industry messaging FAQs
Which messaging channel works for every industry?
SMS, because it reaches every mobile phone in India without internet or an app. Most businesses add WhatsApp, RCS or voice on top for richer or more urgent messages.
Do DLT rules differ by industry?
No. The same DLT rules apply to every business sending commercial SMS in India. What differs is which template category each message belongs to.
Which industries need OTP the most?
Banking, fintech, e-commerce, SaaS and any app with logins or payments. OTP confirms the user holds the phone number on record.
Can one account serve several business units?
Yes. Sub-accounts or separate headers let each unit send and report separately on one platform.
Is WhatsApp allowed for every industry?
Most industries can use WhatsApp Business messaging, but Meta's commerce and business policies restrict some products and services. Check Meta's policies for your category before onboarding.
