We applied the same rigorous process to each piece of email marketing software that we analyzed. The specifics of our email marketing software category research process are outlined below.

Lloyd led our analysis of email marketing software. He has spent more than 150 hours evaluating leading email marketing software systems.

In addition, all research and content was overseen by Bruce Hogan, SoftwarePundit’s Co-founder & CEO. Bruce has more than a decade of experience researching, building, and reviewing the world’s best software products. His technology advice has been featured on a wide range of media sites such as AngelList, CMSWire, Dental Economics, iPhone Life, Reader’s Digest, Thrive Global, U.S. News, and the Zapier Blog.

How We Selected the Best email marketing software

We selected the best email marketing software based upon a number of criteria. The most important criteria were each software tool’s features, usability, price, and customer support. The details of our analyses are captured in the in-depth reviews we publish about each software tool.

There are a handful of critical features that you should look for in email marketing software. We prioritized the following features in our analysis:

  • Data Integration and Storage: Good email marketing solutions allow you to easily and efficiently collect and store audience data.
  • Segmentation | The best email marketing solutions allow you to create complex segments of your audience. Good segmentation tools are key to increasing the relevancy of your emails, and saving cost by reducing send volume.
  • A/B Testing: Most email marketing solutions have A/B testing to optimize different variables like email content, send times, and subject lines. The best solutions allow you to test more variables and email variations in a single test.
  • Drip Campaigns: Email marketing solutions allow you to send a series of automated emails to your audience. The best solutions allow you to build complex workflows with splits and branching points based on your contacts' behavior and data.

How We Evaluated Email Marketing Software

We interviewed the teams at the software companies listed above. Our conversations with the companies included questions about each company’s product, customer base, pricing, customer support, and business strength. After a general interview, Lloyd spent additional time participating in a product demo led by each company. This provided Lloyd with the opportunity to ask detailed questions about the features and functionality of the email marketing software.

Lloyd also obtained a free trial of each software tool listed above. He spent several hours testing the key user journeys in each software product. This allowed us to validate the features offered by each product, and to gain an understanding of the software’s usability.
