Below we break down the best mailing list companies in 2021, the perfect partners to help you find an almost infinite amount of hot prospects to market and advertise to.

Leads Please

One of the most popular direct mail list brokers in the business today, the amount of list generation options and ways to dissect different list groups from Leads Please is almost mind-boggling.

You’ll be able to cross-reference, select out, and break down different lists to find the exact right prospects for your marketing campaigns – all without having to spend a mountain of money on these leads, either.

Another big benefit of using Leads Please is that you don’t have to wonder about pricing.

Unlike many other lead and mailing list companies, pricing isn’t a mystery with Leads Please. They are super transparent, super upfront, and very honest about their pricing – providing full quotes on all of their lead packages.

For example, a test run of direct mail leads (1000 consumer leads) will set business owners back $99.50. Larger runs of 5000 leads will cost about $325, and 10,000 leads will set business owners back between $400 and $800.

To guarantee that the leads they provide their clients are accurate and up-to-date, Leads Please regularly cleans and purges their databases every 30 days. 

Names and list information gets double-checked against USPS authorized and approved software, and email leads are subjected to proprietary electronic confirmation, too.

Combine that with the fact that leads from this company are provided in various formats (PDF, CSV, Excel, etc.), and it’s not hard to see why so many people like moving forward with Leads Please in 2021.

Check out these lists.

Caldwell List Company

If you are looking to reach consumers and aren’t all that interested in business-to-business leads, nobody does this better than Caldwell.

A family-owned operation in the list broker business for well over 45 years, the experience, the wisdom, and the sheer amount of data that Caldwell makes available to their clients is impressive.

Offering both Response and compiled lists generated from various sources (always with total transparency from top to bottom), business owners and marketers will be able to use these lists to generate much more responsive campaigns than they would have been able to elsewhere.

The best part about working with the Caldwell List Company is that each client is assigned their very own list specialist when they start working with the business.

This list specialist will be able to walk you through all the different list options available, help you find and cultivate the most profitable lists, and use their experience and wisdom to help make sure that your leads are as laser-targeted and as red-hot as possible.

Leads from Caldwell are accurate, responsive, and always carefully curated. This company also has a 92% delivery rate for their USPS mailing lists is another reason to lean in this direction, especially if you’re running direct mail campaigns.

If you are looking to run email marketing campaigns instead of more traditional direct mail campaigns, List GIANT is worth a closer look.

With more than 30 years of experience in the list broker world, the email lists provided by this operation are often regarded as some of the best – if not THE best – available today.

Each and every email maintained in the multitude of lists organized by this company have been opted in (many of them double opted in), and all lists are compiled in full accordance with both the United States and Canadian privacy laws, rules, and regulations.

Prices are a little bit on the higher side compared to some of the other operations out there, but at the end of the day, you’re getting fantastic lists, targeted leads, and a multitude of options to help you laser in on your perfect prospect.

It doesn’t hurt that this company also updates their list at least twice and sometimes three or more times each month, constantly adding new prospects, new names, and new opportunities for their clients.

Gunderson Direct

Gunderson Direct has been in business for nearly 20 years and has sent more than 1.5 billion pieces of mail on behalf of clients and customers – and they show no signs of slowing down anytime soon.

You’re not able to stay in the list business for that long or move that much mail volume if you aren’t a reliable partner and a real “mover and shaker” in the marketing world. 

There is a reason companies like Personal Capital, AAA, and Zip Recruiter work with Gunderson regularly.

The folks at Gunderson take a bit of a different approach to working with their clients than other operations.

Instead of seeing themselves exclusively as a list broker, they rather see themselves as strategic partners, wanting to make sure that their clients get the best lists, the best intel, and the best analytics regarding their campaigns (amongst other things).

While not the cheapest list broker on the planet (especially in the direct mail space), they have a solid gold reputation, especially for helping new marketers find their footing and their new customer base.

Their “all-in-one” direct mail services that handle list management, direct mail design and copywriting, and delivery eliminate all the headache and hassle of having to do any heavy lifting on your own, too.

It’s something to consider if you want to outsource this kind of operation truly.

SRDS was once the “only name in town” when it came to list brokers in the direct marketing world, and while that level of influence has waned a little bit in the last few years, they are still a significant player and worthy of consideration.

In the direct mail and list brokerage business for more than 100 years, there’s no other company on the planet with this kind of experience, this kind of data, or this kind of insight into finding the right lists for new marketers, new products, and new services.

Combining Big Data with some of their legacy approaches to list matching, this company understands how to generate the kinds of lists that turn average campaigns into homerun winners!

What’s the Difference Between a Response and a Compiled Mailing List?

There are really two main types of mailing lists that you’ll have an opportunity to rent or buy from list brokers, and those are Response based mailing lists and Compiled mailing lists.

Response-based lists are lists generated from people and prospects that have taken a specific step instead of Compiled mailing lists generated from anyone and everyone that may be tangentially related to that list.

Response lists, for example, are usually made up of buyers, specific hot prospects that have requested marketing information, subscribers, and the like. Compiled lists can be pulled together from public records, questionnaires and registration forms, real estate filings, and demographic details.

Of the two, ResponseResponse-based lists are usually a little “hotter” but are also usually a little bit more expensive.

How Can I Find Mailing Lists That Target My Audience?

There’s a lot of research that goes into finding the right mailing list for your specific audience, as well as drilling even deeper into finding the correct mailing list for your particular product or your particular service that you’re looking to sell with that campaign.

This is why it’s so important to work with professional list brokers that have had real success helping their clients create winning campaigns from the lists that they provide.

Good list brokers aren’t only going to have access to almost unlimited data and contact information. You will also know which lists are the right fit for your business and campaign amongst all the other options you could go with.

What Metrics Help Determine Whether a List is Worth Buying or Renting?

There are a few things you want to look at before determining whether or not a list is worth buying or renting, including:
The relationship this list has with your market, your niche, and your ideal prospect
The completeness of the list and a real absence of duplicate entries
Frequent updates to the list itself, with data purges of old and outdated information
How many other people are using this list, how often they are using it, and when they most recently used at
How the data was compiled (Response lists versus Compiled lists or a mixture of the two)
