  • Popularity is subjective. These popularity scores of email marketing software providers are an approximate scale based on user reviews and market presence that we have been able to gather at this point. This can change in the future.
  • The target audience is difficult to determine. Remember, each email marketing platform might cater to a wide range of businesses. Their tools and features could potentially be used by anyone from a single individual to a large corporation, depending on specific needs and circumstances. For the most accurate and up-to-date information, I recommend consulting each provider’s website and available documentation.
