Who are the Best B2B Email List Providers?

7 minute read

Let’s face it, B2B lead generation is hard. I’m sure all of us have thought about or tried many new ways to increase our leads and contact information. From gated content and email lists to remarketing campaigns, it’s difficult to find new leads to reach out to. There’s a good chance that you’ve considered whether it’s worth it to buy an email list.

B2B email lists can be used in a variety of ways. The most common is cold email prospecting. This is generally the easiest way to use email lists because you already have a list of people to reach out to. You can save a lot of time compared to finding email addresses on your own. Who wouldn’t want to save time? Then, you can shoot out an email campaign to hundreds or even thousands of subscribers in one go. You can also use the email to find leads on LinkedIn, and reach out there.

But not all B2B email list providers are created equal. There are ethical considerations to keep in mind, as some people do not like to be contacted randomly. In addition, you should also consider if the list is “warm” with possible leads. Meaning, if you find 100 emails, but none of the emails are relevant for your company, it can be a waste of time and money.

In this guide, we’re discussing whether buying an email list is worth it and, if you do take that route, which B2B data providers can be trusted to offer the best results for your company. Before we jump into the list of the best B2B email list providers, we’re going to quickly go over a few common questions that we see about buying an email list.

Is it Worth Purchasing B2B Data?

Who are the Best B2B Email List Providers?

In short, yes. Purchasing a list of potential leads can save you loads of time compared to manual outreach. However, you’ll want to find a reputable data provider to ensure that you get your time and money’s worth. There are a lot of companies out there that are not reliable sources of data and can end up scamming you.

Once you have completed your research, the first step that you want to take is buying an email list. You should buy an email list that is relevant to your company. This means the list is full of subscribers who are likely going to be interested in what your business has to offer. That may mean that they work in your industry or have bought products that are similar to yours in the past. Buying an email list of small business owners who are interested in digital marketing when you offer legal services to corporations may not result in many conversions. The more specific of a list you want, the more expensive it’s going to be. Plus, there’s always the chance that it won’t be as specific as you’d like.

Like I mentioned before, without relevancy, subscribers are likely to unsubscribe. Don’t waste your time and budget on a list of cold subscribers who are unlikely to work with you or buy your products.

All that being said, it is worth it to buy B2B data if you anticipate a return on your investment. Now, it’s a matter of finding an email list provider that can be trusted to deliver the goods.

Where to Buy an Email List

If you do a Google search of “buy email list”, you’re likely to get some pretty sketchy and not-so-reliable results. That’s because many list providers are in the business of scraping the web for random email addresses and selling them off to turn a profit.

These scraping tools typically provide low-quality results. They may be completely dead or considered spam, so there would be zero return. Running a campaign to these email addresses is likely to hurt your deliverability rate and conversions. Essentially, it’s a waste of time, money, and resources to go this route.

A better approach is to find a B2B email list provider that can offer a list of contacts that are within your target audience. Ideally, they will be segmented by certain demographics, interests, or past purchasing behavior. This will make it easier for you to 1) determine the value of the list and 2) tailor your campaigns to that unique set of subscribers that will actually be interested in what your company has to offer.

Another approach is to use lead generation software to create a list of contacts based on who have already visited your website already. With this approach, you know that the visitors are at least interested in your business. Plus, if you’re worried about being scammed, a lead generation software is a more reliable source of leads because they are coming from a reputable company. Then, you can run a campaign for the people who have already been to your website and not worry about the legitimacy of your leads.
