Most Lusha reviews are written from a North American desk selling to North America, which makes them useless for the question a Vietnamese team actually has: does this work for us, given where our customers are?
The answer splits cleanly, and it is worth stating plainly rather than hedging. Lusha is strong for the markets Vietnamese agencies, SaaS companies and outsourcing firms sell into. It is weak for selling inside Vietnam. If your ICP is abroad, that split works in your favour.
Where the coverage is genuinely strong
Lusha publishes roughly 290-300 million verified contacts and more than 26 million companies, with claimed 98% email accuracy and around 86% phone accuracy. The strength is concentrated in the United States, United Kingdom, Canada and Western Europe.
That is precisely the export market for most Vietnamese B2B teams — development outsourcing, design and marketing agencies, and SaaS products aimed at Western SMBs. If you sell to a company headquartered in Austin, London or Berlin, you are buying Lusha in the exact region where it performs best, and the direct-dial database is a real advantage over email-only providers.
Where it thins out
Coverage in Asia-Pacific is noticeably weaker, and Vietnam and most of Southeast Asia are among the thinnest areas. You will usually find the company record and often an email pattern, but mobile numbers for mid-level managers at Vietnamese companies are inconsistent.
This is not specific to Lusha — it is a structural feature of Western-built B2B databases, where coverage follows LinkedIn density and public company filings. But it means one thing concretely: if your customers are domestic, do not buy Lusha on the strength of its published accuracy figures. Those figures describe a different continent.
For domestic prospecting, a local network, industry associations and direct research still outperform any international database, and cost less.
The timezone problem nobody mentions
A direct dial is only useful if you can call it. Vietnam is UTC+7. US Eastern business hours land between 8pm and 5am Vietnam time; US Pacific is worse. Western Europe is more workable — a Vietnamese afternoon covers a European morning.
This changes how you should spend credits, not whether you should buy them. If your team cannot staff a late shift, the phone number you paid 5 credits for is an asset you cannot use, and you would be better off spending 5 credits on five verified emails instead.
Teams selling to the US that do want the phone channel usually solve it one of two ways: a small dedicated late shift two or three evenings a week, or European accounts on the phone tier and American accounts on email-only. Both are fine. Paying for phone credits and never dialling them is not.
A sensible starting configuration
For a Vietnamese team of two to five people selling into Western markets, this is where we would start.
- Free plan first, for two weeks. Spend all 40 credits on 8 phone numbers in your actual target market and call them. Your connect rate is the whole decision.
- If you go paid, Pro at the annual rate — about $52.45/month for two seats and 7,200 credits a year. Starter's single seat is usually too tight once a second person joins.
- Split the credit budget deliberately: emails for the US, phones for Europe, if timezone is your constraint.
- Pair it with a CRM you already have. HubSpot's free tier is enough to start; Close is the upgrade if call volume is your bottleneck.
- Add a VoIP line rather than dialling internationally from a mobile. KrispCall and similar services give you a local presence number, which materially changes pickup rates on cold calls.
The compliance angle matters more here, not less
A Vietnamese company selling into the EU is fully within GDPR scope, and that surprises teams regularly. The regulation follows the data subject, not the seller.
This is where Lusha's certification stack — ISO 27701, ISO 27001, SOC 2 Type II, documented GDPR and CCPA processes — stops being abstract. When a European client asks where you sourced their team's contact details, being able to name a certified provider and produce their documentation is a complete answer, and it is an answer a cheaper scraped list cannot give you.
For a team whose main competitive challenge is being taken seriously by Western buyers, that is worth more than the credit price difference.
