Why Do You Need B2B Email List Providers?

According to Dun & Bradstreet, 35% of sales and marketing teams say one of the biggest challenges they face is data accuracy. The possible reason for this is manually gathering data, which results in erroneous contact information.  

So, you can solve this problem by using a B2B email list provider that gives you accurate and reliable data. It also saves you time and money, helps you personalize your outreach, and expand your business in new markets. 

Let’s delve deeper into how a B2B email list provider helps you scale your email outreach campaigns: 

1. Data Accuracy

LinkedIn's State of Sales reveals 2 of the biggest data-related challenges that nearly half of sellers face today: incomplete data (48%) and inaccurate, out-of-date data (41%). 

Even when you've invested a lot of time and money in building your business email lists, there could still be gaps. You might have overlooked certain companies, missed opportunities, or struggled to find updated contact information for some accounts.

Having inaccurate or outdated data in your B2B email list can result in bounced emails or, worse, your emails being marked as spam. This can damage your sender reputation and harm your deliverability.

To help your cold emails land successfully in your prospect’s primary inbox,  reputable B2B email list providers maintain high-quality databases with accurate and up-to-date contact information. Buying from them ensures that you are reaching out to relevant and active prospects.

2. Time and Cost Efficiency

Creating an in-house B2B contact database requires extensive research to identify and collect relevant information about potential leads. It involves searching through various sources, such as business directories, websites, and industry publications, to gather accurate and up-to-date contact details.

Once the data is collected, it needs to be verified and updated continuously to ensure accuracy.

All these tasks are time-intensive, and errors may still occur.

When you automate this process with B2B mailing list providers, compiling, verifying, and updating extensive databases of business contacts can be done in no time. This means that your team can focus on selling and closing more deals. 

3. Establish a Foothold in New Markets

As your business grows, you may want to expand into new markets and seek opportunities beyond your current customer base. 

But, Entering a new market is not easy. It involves a learning curve to understand the nuances, preferences, and challenges unique to that market. But when you are bound by time constraints and lack of resources, it becomes challenging to dedicate time and effort to researching and building email lists from scratch. 

With B2B email list providers, you get access to targeted lists of key players, decision-makers, and influencers within a new market that fit your ICP, and leveraging this list helps sales and marketing teams bypass some of the learning curve, significantly reduce the time it takes to make initial connections and establish a stronger foothold in a new market.

4. Run Personalized Outreach Campaigns

Knowing your audience accurately enables you to deliver content that is relevant and valuable to them. 4 out of 5 marketers personalize emails with profile data, and 64% personalize them by customer segment. 

When messages resonate with the recipients, they are more likely to take the desired action, whether it's requesting more information, scheduling a demo, or making a purchase.

B2B email lists provide detailed information about prospects, including their industry, job roles, and company size. With this data, you can segment each lead to craft highly targeted and personalized messages. This increases the likelihood of getting responses from your prospects and gaining their trust.

How Do You Choose the Best B2B Email List Provider?

Most B2B email list providers aggregate data from a single source. They lack comprehensive coverage for specific regions or industries, making it difficult to find relevant contact details.

One way to get more data could be pouring money into multiple data providers, but we know you don’t want to burn a hole in your pocket. 

So, which B2B email list provider gives you highly verified email data while remaining cost-effective? The answer is Prospect IQ by Klenty. 

What makes Prospect IQ a powerful tool for B2B email list building is it addresses a common challenge in single-source contact databases by employing the waterfall lead enrichment model. 

This lead enrichment model aggregates data from multiple vendors and carries out multiple enrichments on top of each other. The result? You get 700% more email and phone data, making it easy to enrich your database with verified contact details in just one click. 

Having reliable data allows you to execute precise account-based prospecting, helping you identify accounts that match your ICP, target the right stakeholders, and create personalized email campaigns.
