Email parsing API is a tool that connects two software products: one is an email and the other is one of your own choice. So basically any API is an intermediary for two programs that want to work together. Email API in particular deal with information inside emails and ‘translates’ this information so that the other party of the process will understand and use this information. For example, you got an email with a timetable for a conference. What an email parsing API can do is to extract this information directly to your calendar in no time. So that you can be sure you won’t miss any interesting lectures or meetings.
