If you're buying B2B contact data for outbound sales, cold email, or lead generation, I'd start with UpLead if verified email accuracy is your top priority, and Apollo if you want the best all-around value.

There is no single "best" B2B database because the right choice depends heavily on your budget, target geography, and whether you want a pre-packaged list or a real-time prospecting tool.[](https://www.unifygtm.com/explore/b2b-data-providers-contact-accuracy-comparison)

I can recommend the most cost-effective provider for your workflow.
If you mean a legitimate B2B prospecting database with business emails, there are several established options:
A key distinction: I'd avoid buying a random CSV of 100,000 "verified emails." A live database that lets you filter and verify contacts is generally more useful because B2B contact information changes frequently.
Be careful about compliance. For example, UK rules distinguish corporate subscribers from sole traders, and privacy laws can still apply when you're processing an individual's business contact information.
If you tell me (1) what industry you're targeting, (2) what country, and (3) roughly how many contacts you need, I can narrow this down to the most suitable databases and approximate costs.
