What Is a List Building Service (and Why Should You Use it)?

List building creates a database of people who would benefit from your product or service.

You then use the list of contact info to nurture your potential clients, targeting people who care about what you’re selling. Learn more about creating a robust B2B list here.

But you don’t want to be reaching out to just anyone. Sales teams spend a good portion of their day finding quality leads and hours of internet research to find quality contact data.

List building services use automated tools to find valid emails and phone numbers. You can then create and export lists to Excel or your CRM, integrating them into your sales pipeline.

Custom list building services like UpLead use your desired filters to comb through millions of people and leave you with your ideal contacts. They use verified email addresses to keep your email lists safe and out of the spam box. 

The best part is that you have more time to reach out to your potential customer base. And this time, you’ll reach out to people likely interested in high-quality prospect lists. Learn more about finding sales leads here.

Of course, there are other options. You can build lists by hand, taking up time you could spend reaching out to ideal customers. You can hire an agency to filter through data, but that will cost you lots of money.

Or you could leave it to an accurate list of building services that do all the work for you — without the hefty price tag.
