1. Very intuitive- The functions and features are self-explanatory and easy to understand, even for a new user. 2. Flexible Features- The features are much more advanced than the competitors. I have used multiple such platforms and found the functions in phpList to be superior. 3. Much more secure than the competitors in terms of preserving data. 4. Superior UI interface.

phpList is a historical software for direct email marketing based, as the name suggests, on PHP language. phpList offers its users maximum flexibility and reliability in managing promotional campaigns via email. Thanks to this tool it is possible to generate targeted messages for each type of customer, in order to improve the effectiveness of the marketing campaign. phpList allows you to divide the subscribers of email marketing services into specific lists (as for example Mailchimp) and allows you to create and use multiple models. phpList prevents a recipient from receiving the same message several times, even if his address is present in more than one list. In addition, it allows you to make a further submission exclusively for users who have registered after sending the newsletter.

To me the script does the job, but if you look a little deeper you can't find anything.
