Market overview

Bangladesh is one of the world's fastest-growing economies, driven by a garment and textile sector that is second globally only to China. Dhaka, the capital, is one of the world's most densely populated cities and the hub of Bangladesh's commercial, financial, and emerging technology activity. Chittagong is the port city that handles almost all of Bangladesh's export trade. Bangladesh has produced the world's cheapest garments for decades — companies like H&M, Zara, Primark, and virtually every Western fast fashion brand source from Bangladeshi manufacturers. A growing technology sector and government investment in digital infrastructure are diversifying the economy.

Primary business hubs: Dhaka (Gulshan, Banani business districts), Chittagong, Sylhet, Rajshahi.

Outreach benchmarks & strategy

Bangladeshi B2B cold email in English is standard for the technology and professional sectors. The garment and manufacturing sector operates through established sourcing relationships, trade shows (Dhaka International Textile and Garment Machinery Exhibition), and buying house networks rather than cold outreach. The growing IT sector in Dhaka is internationally oriented and responds to professional direct outreach in English.
