Hire a team of researchers rather than buying a list of leads

Automated software cannot target niche industries and job functions, but manual research by experts can. Since we function as data partners, our corporate email lists are tailor made for each client. These business data lists are unique and not belonging to commonly demanded industries, shared by multiple competitors.

GDPR compliant business profiles with highest privacy standards

We comply with all data privacy norms. We do not store data lists, but delete them after the final submission to the client. Every mailing list is freshly built and made-to-order, to fulfil the unique specifications of each new client.

We build Custom B2B Contact lists with multiple Data Attributes

To build a custom Contact database, you don’t need just a list of email addresses and phone numbers. Your email database needs to be populated with contact, company, and firmographic details, to give you a complete picture of your leads. This allows you to segment your data to identify ideal prospects and reach out to them in a more personalised way.

What are Email Finder Tools and Email List Builder Tools?

Email finder or email list builder tools help you find email addresses, direct phone numbers, company names, social media profiles, company revenue and a lot more contact and company information. Their algorithm indexes a huge number of web pages to source information, and builds and stores extensive databases. These tools help you build a lead list for marketing, sales, and business development, using a browser extension, API or web interface.

If you want to evaluate various email finder software platforms, their pros and cons, and also discover ways to overcome the drawbacks of such software tools, this is the best place for you.

Our Email List Research is more Effective than Email Finder Tools

The main problem with email finder tools is data inaccuracy, because tools run on automated software processes. Secondly, building a database of contacts from niche industries and job roles, and updating them in real time is practically impossible. The solution lies in doing away with pre-built databases that rely solely on software automation. Today companies that function as data partners have found a way to circumvent the problem of outdated databases by using a combination of automated processes along with human research and validation.

In case a prospect has switched jobs we give you a replacement contact immediately, and also charge only for successful contacts. The second part of the solution lies in building your email list, from the ground up, through customised research methods. Data is never stored in databases that are accessible to hundreds of users. Email addresses and phone numbers are manually validated through phone research as well as email verification tools. Consent is obtained through single and double opt-ins.

Clients have full control over their data. They can be sure the prospect they are targeting wants to receive their marketing and sales messages. They are also assured that their data is unique from that of the competition.
