SMS marketing in Bangladesh works best when messages are short, relevant, well-timed and sent only to people who want them. A promotion sent between 09:00 and 21:00 Bangladesh time, from a recognisable brand name, with a clear offer and an easy opt-out, will usually outperform a long, generic blast. Here are 12 practical tips to get more from every campaign.

Why does SMS marketing still work in Bangladesh?

SMS reaches every mobile phone, including basic phones without internet, on every operator: Grameenphone, Robi, Airtel, Banglalink and Teletalk. It does not depend on social media algorithms or app installs. For shops, restaurants, e-commerce, clinics, schools and service businesses, it is one of the most direct channels to a customer you already know.

Only send promotions to people who have given you their number and agreed to receive offers: at checkout, through a sign-up form, or at your shop counter. Buying lists or scraping numbers damages your brand, wastes money on uninterested people and can break operator and BTRC rules. A smaller list of real customers is worth far more.

2. Always offer an opt-out

Tell customers how to stop receiving promotions, for example by replying or contacting you, and honour the request quickly. Keep a "do not message" list and remove those numbers from every future campaign. Respecting opt-outs keeps complaints low and your sender reputation healthy.

3. Send within 09:00–21:00 Bangladesh time

Promotional SMS can only be sent between 09:00 and 21:00 Bangladesh time. Within that window, think about your audience:

  • Office workers often read messages at lunch or after work.
  • Restaurant and food offers do well before meal times.
  • Avoid very early or late slots inside the window, when messages feel intrusive.

Use scheduled sends in the dashboard to time campaigns precisely.

4. Plan for content approval

On GotiSMS, the exact text of every promotional campaign is submitted for operator approval before it goes out. Do not leave big campaigns to the last minute. Finalise the text, submit it early, and avoid changes after approval, because a new text means a new review.

5. Use your brand name as the sender

A masking sender ID shows your brand name, up to 11 letters, instead of a number. Customers recognise you before they even open the message. Sender IDs need approval, so apply well before your first campaign. Learn more about masking SMS.

6. Get to the point in the first line

Many people only read the notification preview. Put the offer first:

GotiShop Eid offer: 20% off all panjabi till Friday. Shop: gotishop.example/eid

Brand, offer, deadline and action: that is all a good promotional SMS needs.

7. Choose Bangla or English deliberately

Bangla feels personal and works well for festivals, local shops and audiences who prefer reading Bangla. English fits more text per SMS and suits short, functional offers for urban app users. Remember the cost difference: a single English SMS holds 160 characters, a single Bangla (Unicode) SMS only 70, and billing is per part. One emoji also turns a message into Unicode. Read Bangla SMS character limits before writing.

8. Build campaigns around Eid

Eid-ul-Fitr and Eid-ul-Adha are the biggest shopping seasons of the year. Ideas that work:

  • Early-bird offers in the weeks before Eid, when people plan purchases.
  • Last-order reminders before courier cut-off dates.
  • A short Eid greeting to loyal customers, without a hard sell.

Because promotional text needs approval, prepare all your Eid messages in advance and submit them early.

9. Celebrate Pohela Boishakh and national days

Pohela Boishakh (Bangla New Year) is ideal for Bangla-language messages, new collections, special menus and loyalty rewards. Other national and cultural dates can also be good moments for a greeting or an offer, as long as the message stays respectful and relevant to your business.

10. Ride the big online sale days

Online sale events such as 11.11 and 12.12, along with year-end and Black Friday-style sales, have become popular with e-commerce shoppers. Use SMS for:

  • A teaser a day or two before the sale.
  • A "sale is live" message on the morning.
  • A final-hours reminder before 21:00.

Keep the number of messages reasonable. Three well-timed messages beat ten in a row.

11. Segment your contacts

Not every customer wants every offer. In the GotiSMS dashboard, organise contacts into groups, for example by location, past purchases, or customer type, and upload lists from Excel or CSV. Send baby-product offers to parents, Dhaka delivery deals to Dhaka customers, and VIP discounts to repeat buyers. Relevant messages get better results and fewer opt-outs.

12. Measure, learn and repeat

After each campaign, check delivery reports on the Campaigns page and compare them with what happened in your business: sales, coupon codes used, website visits from a tracked link, or calls. Test one thing at a time, such as send time, Bangla vs English, or offer type, and keep what works. Save winning messages as templates for next time.

Common SMS marketing mistakes to avoid

  • Sending the same promotion several times a day.
  • Long messages that run into three or four parts and multiply your cost.
  • Vague offers with no deadline or action.
  • Messaging numbers that never opted in.
  • Forgetting that promotional content needs approval and leaving no time for it.
