ContactDatabases.

Buying static contact databases wastes budget and burns your email domains. Most pre-packaged B2B lists are 30% to 50% outdated before you even download them.

We mine custom decision-maker databases on demand. Every record is scraped directly from live sources and verified via real-time SMTP server handshakes — guaranteed strictly under 2% bounce rate.

Frequently Asked Questions

Why shouldn't I buy a pre-packaged B2B contact list?+
Pre-packaged contact databases decay at 3% to 5% every month as people change jobs. When you download a static CSV, up to 35% of emails bounce immediately, which flags your sending domain as spam on Google and Microsoft servers.
How does Manumerc verify email addresses?+
We perform direct, live SMTP handshakes with recipient mail servers at the moment of mining. We verify MX records, mailbox existence, and spam-trap absence without sending an actual email. We guarantee bounce rates strictly under 2%.
What data points are included in each prospect record?+
Each record includes full name, verified direct work email, job title, seniority level, LinkedIn profile URL, company name, website domain, company head count, industry, and corporate headquarters location.
Is your prospect data GDPR compliant in the UK and EU?+
Yes. All data is collected under legitimate interest provisions for business-to-business communications, sourced exclusively from publicly available business registers and executive profiles.
