Poastal is an innovative email Open Source Intelligence (OSINT) tool that offers a wealth of information about any given email address. Designed to answer several key questions about an email address, Poastal is a crucial tool for anyone seeking to gather intelligence from email data.

What Poastal Does:

Poastal provides a range of features that help users understand more about an email address. These features include:

  2. Checking if the email is deliverable or not.
  3. Identifying if the email is disposable or not.
  4. Checking if the email is considered spam.
  5. Checking if the email is registered on popular platforms such as Facebook, Twitter, Snapchat, Parler, Rumble, MeWe, Imgur, Adobe, WordPress, and Duolingo.

How to Use Poastal:

Using Poastal is as simple as opening the index.html file in the root directory to use the User Interface (UI). Once the UI is open, enter an email address and see the results. You can test the functionality with an example email address, such as [email protected].

There’s also a new GitHub module. If you open up github.py, you’ll see a section that asks you to replace it with your own API key.
