How to Run Effective Bulk SMS Campaigns

With a 98% open rate, SMS remains the most effective direct marketing channel — especially in Bangladesh where WhatsApp and SMS are the primary communication methods.

Why SMS Works Better Than Email

• 98% open rate vs 20% for email
• Read within 3 minutes of delivery in 90% of cases
• No spam filters — messages always reach the recipient
• Works on all phones — no smartphone or data required

Types of SMS Campaigns

Promotional SMS

For marketing offers, product launches, and seasonal promotions.

"EID SALE! 40% off all orders today only. Shop now: [link]"

Transactional SMS

For order confirmations, payment receipts, and delivery updates.

"Your order #12345 has been shipped. Track here: [link]"

OTP / Authentication

For app login, payment verification, and account security.

"Your OTP is 847291. Valid for 5 minutes. Do not share."

Best Practices

Keep it short — under 160 characters for a single SMS

Include a clear CTA — what do you want them to do?

Send at the right time — 10am-12pm and 5pm-7pm get best results

Personalize — use the recipient's name when possible

Respect opt-outs — always honor unsubscribe requests
