One of the most perilous mistakes in bulk number marketing, especially in Bangladesh, is disregarding local regulations and compliance frameworks. Unlike many Western countries, Bangladesh has its own specific telecommunications policies and evolving data privacy considerations. Sending unsolicited commercial messages (SMS or voice calls) without proper consent can lead to severe penalties from regulatory bodies like the Bangladesh Telecommunication Regulatory Commission (BTRC). This includes potential fines, blocking of sender IDs, and even legal action. Beyond legal repercussions, non-compliance erodes trust with consumers who are increasingly sensitive to unsolicited communication. Always prioritize obtaining explicit, verifiable consent, adhere to "quiet hours" (often 9 PM to 9 AM), and understand sender ID registration requirements to ensure your campaigns are both effective and lawful in the Bangladeshi context.
Failing to Segment Your Audience: Spray and Pray Approach
A monumental mistake in bulk number marketing is adopting a "spray and pray" approach, sending generic messages to an undifferentiated mass of numbers. This is akin to shouting into a void and hoping someone hears you. In 2025, consumers expect relevance, even from bulk communications. Failing to segment your audience based on demographics, geographic location within Bangladesh (e.g., Dhaka vs. Chittagong, whatsapp data urban vs. rural), past purchase behavior, or inferred interests leads to abysmal engagement rates and high opt-out figures. Instead, leverage available data to create distinct segments. For instance, send specific offers for winter clothing to customers in cooler regions during the appropriate season, or promote academic supplies to students during exam periods. Segmentation ensures your bulk messages, while broad, still carry a degree of personalized relevance that maximizes impact and minimizes annoyance.
Neglecting Message Personalization: The Cold, Impersonal Touch
Even in bulk marketing, neglecting personalization is a critical error. While full 1:1 personalization for every message might not be feasible, a complete lack of it results in a cold, impersonal touch that alienates recipients. This goes beyond just including a customer's first name. It involves incorporating relevant details based on your segmentation, such as mentioning a previous purchase, referencing a specific product category they've shown interest in, or acknowledging a local event or holiday (e.g., Eid Mubarak messages). The goal is to make the recipient feel that the message, though part of a larger campaign, was still intended for someone like them. This simple yet powerful strategy significantly increases engagement, builds rapport, and prevents your bulk messages from being immediately dismissed as irrelevant spam.
