What is SMS marketing
A direct line to your customer, no app or inbox required.
SMS marketing is the practice of sending text messages straight to a customer's mobile phone, either as promotional messages (offers, announcements, campaigns) or transactional messages (OTPs, order updates, appointment reminders, and other account-related alerts).
Unlike email or social media, SMS does not depend on an app being open or an algorithm deciding who sees it. It lands in the one place almost every customer checks first: their phone's message inbox.
- Read by most recipients within minutes of delivery
- Delivered directly, with no spam filter or algorithm in the way
- Works alongside email for a stronger, multi-channel campaign
- Reliable even in low-connectivity or low-data areas
Why SMS works
A channel customers actually open.
Four reasons SMS consistently outperforms other channels for time-sensitive and high-intent messages.
Direct Line to the Customer
Messages go straight to the phone in the recipient's hand, with no inbox clutter or news feed competing for attention.
Complements Email Marketing
Pairing SMS with email gives you two channels reinforcing the same campaign, improving overall reach and response.
Reliable Even With Low Data
SMS runs on basic cellular network signal, so it reaches customers reliably even with a weak or no data connection.

FAQs
Common questions about bulk SMS.
What is the difference between promotional and transactional SMS?+
Promotional SMS covers marketing and offers, and cannot reach DND-registered numbers. Transactional SMS covers order updates, OTPs, and account alerts, and is delivered to all numbers, including DND, at any time.
Can I send SMS to DND-registered numbers?+
Not with promotional SMS. Transactional SMS, however, is delivered to DND numbers as well, since it relates to a customer's own transaction or account.
Do SMS credits expire?+
No. Every package comes with lifetime validity, so unused credits remain available with no expiry date.
Is an API available for sending SMS?+
Yes. Our Transactional SMS with API packages include full API access, so OTPs and alerts can be triggered automatically from your website, app, or CRM.
How do I get a Sender ID for my business?+
We handle the Sender ID registration and DLT approval process for you as part of onboarding, so your messages go out under your business name.
What support do I get after purchasing a package?+
Every package includes 24/7 support, so you can reach us for delivery issues, template approvals, or account questions at any time.
