Generates a custom email address with timestamp from the input email address.
java -cp path/to/directory/timestamp-email TimestampEmail yourname@example.com
yourname+2021.03.31.08.09.16@example.com
java -cp path/to/directory/timestamp-email TimestampEmail <email-address>
I have it bound to a keyboard shortcut for convenience
javac -classpath path/to/directory/timestamp-email TimestampEmail.java
The email address stays on the clipboard for 5 seconds so paste quickly.
