15 Best Mailing List Companies In USA: A Guide for 2024

As a marketer or business owner, you might have noticed that some of the most promising marketing campaigns you developed never achieved the desired results. Maybe you had the right message, the right offering, the right tools, and yet you fell short on results.

In most cases, the mailing list is the reason for such failures or subpar results. Even after spending ridiculous amounts of money on mailing lists, businesses may not get the desired results. Having validated contacts in your marketing list is not good enough if it doesn’t have the relevant target audience.

How To Ensure You Get Quality Mailing Lists For Your Business?

Every company has its unique marketing requirements, and it can change drastically across different industry verticals. However, certain aspects are common to all mailing lists, and you can use them to ensure that you have top-notch mailing lists. Listed below are four steps for ensuring the reliability of your mailing list provider.

Step 1: Defining Your Target Audience

Every business marketing campaign needs to have a well-defined target audience. It is the most fundamental thing you need to know before strategizing your marketing efforts. Furthermore, a business can have more than one target audience based on the type of products or services it sells.

However, it might not be suitable to take the same marketing approach or strategy for a different audience. Even the marketing channel you use can vary significantly based on your target audience. Hence, make sure that the mailing list brokers you consider allow you to define your target audience freely.

Step 2: Picking Your Mailing Strategy 

Before implementing a direct mail campaign for your business, you need to develop an effective mailing strategy. Find out what mailing list technique can work best for maximizing your reach to a specific target audience.

Some of the primary considerations while selecting a suitable mailing list for your business are the following:

  • Your budget
  • Your timeline
  • Short and long-term campaign goals

Saturation mailing and targeted mailing are two of the most popular choices for direct mail campaigns. The former is relatively less expensive but also has a lower response rate. On the other hand, targeted mailing lists get you more quality leads but are often more costly. Make sure that the listserv companies you are considering allow you to choose your mailing strategy.

Step 3: Segmentation Of Your Mailing Lists

The next thing you should do is check whether the mailing list companies you are considering allow the segmentation of mailing lists. Segmentation is a vital part of creating successful marketing campaigns for your business. It enables you to provide more relevant offers to your customers based on their needs.

In other words, you can focus your marketing efforts on a closely- defined group of people. Some of the standard segmentations you can try for marketing your business includes the following:

  • Geographic
  • Demographic
  • Behavioral
  • Psychographic

Step 4: Testing Your Mailing Lists

Before picking a mailing list provider for your business, you must take the final step to test their list. Most established mailing list providers such as PostGrid offers a free trial or demo. Use the trial or demo from the mailing list company to check whether they meet your expectations.

A few elements you can consider when testing out the mailing lists are:

  • Segmentation
  • Formatting
  • Offers/Pricing
  • Creative Elements

The points above give you an idea of what you should check during the testing phase. Ensure that you consider all your unique business requirements before testing your mailing list. Furthermore, you should also consider other factors such as budget and time contractions during this phase.

Print and mail documents online

Our intuitive, collaborative tools allow you to focus on your email campaigns and our deliverability tools help ensure that they reach your customers’ inboxes.



Mailing Lists can potentially decide how well or how bad your marketing campaigns go. It is, therefore, necessary to choose from the top mailing list companies to ensure the best results for your business. However, with so many mailing list providers in the US, it can be challenging to choose one from them.

Above, we have discussed all the major companies you can consider for getting your mailing lists. PostGrid is the clear winner when it comes to providing high-quality mailing lists for your direct mail campaigns.
