Fewer than you might think. In Saella's company data, most industries in Vietnam, Singapore and Malaysia have an email for 1 in 7 to 1 in 14 companies. In Indonesia and the Philippines it is usually 1 in 20 or worse, and in some industries worse than 1 in 70.
We pulled these numbers from the Saella app on 6 November 2026. Here is every figure and what it means for cold email.
Key Takeaways
Vietnam has the best email coverage: 1 in 7 to 1 in 11 active companies have an email, in every industry we checked (Vietnam is the only country counted on active companies only).
Singapore and Malaysia sit in the middle. Most industries are 1 in 9 to 1 in 14, with lower coverage in restaurants and real estate (Singapore) and education and health (Malaysia).
Indonesia has the lowest coverage overall. Logistics is 1 in 33. Education is 1 in 92.
The lowest single figure is Philippine education: 1 in 184.
IT and software is the most consistent industry: 1 in 9 in Vietnam, Singapore and Malaysia, and the best industry in Indonesia and the Philippines.
How many B2B companies in Vietnam can you email?

Wholesale: 12,437 companies, 1,613 with email, 1 in 8

How does the same industry compare across countries?
Each industry, from best to worst:
Logistics: Vietnam 1 in 7, Malaysia 1 in 10, Singapore 1 in 13, Philippines 1 in 26, Indonesia 1 in 33
Construction: Vietnam 1 in 11, Malaysia 1 in 14, Philippines 1 in 23, Indonesia 1 in 27
Wholesale: Vietnam 1 in 8, Malaysia 1 in 10, Philippines 1 in 22, Indonesia 1 in 26
IT and software: Vietnam, Singapore and Malaysia 1 in 9, Philippines 1 in 17, Indonesia 1 in 20
Restaurants and food service: Vietnam 1 in 7, Malaysia 1 in 18, Singapore 1 in 20, Philippines 1 in 45, Indonesia 1 in 68
Real estate: Vietnam and Malaysia 1 in 11, Singapore 1 in 17, Philippines 1 in 31, Indonesia 1 in 73
Education: Vietnam 1 in 8, Singapore 1 in 9, Malaysia 1 in 24, Indonesia 1 in 92, Philippines 1 in 184
Health: Vietnam 1 in 7, Singapore 1 in 9, Malaysia 1 in 24, Indonesia 1 in 72, Philippines 1 in 89
The countries split into two groups: Vietnam, Singapore and Malaysia, then Indonesia and the Philippines. IT and software has the smallest gap between countries. Education and health have the largest.
A big company count does not mean a big email list. Indonesia has more education companies in our data than Singapore (21,629 vs 20,320). Singapore has 2,239 with an email. Indonesia has 236.
What does this mean for your outreach?
The ratio shows how far email alone can take you.
Count your reachable list before you write a single email. If you sell to Indonesian real estate firms, our data has 72 with an email. That is enough for a careful, personal campaign, not a volume play. Check the number first, then plan copy and follow-ups.
Email works well at about 1 in 15 or better. Most B2B industries in Vietnam, Singapore and Malaysia clear that bar, so you can run a normal sequence. Our cold email templates and follow-up email guide are a good start.
Add other channels at 1 in 20 or worse. In Indonesia and the Philippines, most companies in each industry have no email in our data. Email-only outreach skips most of the market. Plan phone, WhatsApp or LinkedIn from the start, and email the companies that do have an address.
Protect a small list. When the list is short, every bounce and spam complaint matters more. Verify addresses, warm up your domain and keep volume steady. See our guide to cold email deliverability.
How we counted
We used company search in the Saella app on 6 November 2026. For each country and industry, we counted all companies and companies with at least one email. We divided the first by the second and rounded to get "1 in N".
Industries are grouped by ISIC divisions: logistics 49 to 53, construction 41 to 43, wholesale 46, manufacturing 10 to 33, restaurants 56, real estate 68, education 85, health 86. IT and software uses ISIC classes for software publishing, programming, IT consulting and data processing.
Food and beverage manufacturing (10 to 11) is part of manufacturing, so do not add the two together.
Active companies. Only Vietnam counts are filtered to active companies. In the other four countries the active filter returns all companies, so those are "companies in Saella's data" and may include some that no longer trade.
Data date. The data includes companies founded up to 7 October 2026. Newer companies are not counted.
Left out. Singapore construction and wholesale, and Malaysia manufacturing, are left out because the count was incomplete.
Limits. These numbers describe Saella's data, not every company in each country. "With email" means at least one address on record. It may not reach a decision-maker. Because Vietnam counts only active companies, its totals are not directly comparable with the others, and its ratios may look better partly because closed companies are filtered out. Treat the country comparison as a guide, not an exact ranking.
