+
+### What is this?
+
+48hr.email is my very own tempmail service. You can create emails on the fly with one click, not needing to worry about corporations do with your email. They can sell that one all they want!
+
+All data is being removed 48hrs after they have reached the mail server.
+
+<br><br>
+
+-----
+
+### How does this work?
+
+48hr.email uses an existing IMAP server for its handling. A single catch-all account and the accompanying credentials handle all the emails.
+
+<br><br>
+

+
+### How can I set this up myself?
