Temporary mail script?

Hello! I'm curious if anyone has created a temporary email script. Currently, I'm using an Alfred workflow, which can be found here: Alfred Workflow.

I lack programming knowledge and attempted to copy the script into BetterTouchTool, but it doesn't seem to work. However, it seems like it shouldn't be difficult for BTT to execute a script like that and copy/paste the temporary email address output.

I'm mainly wondering if someone has already created a version of this. Additionally, temp-mail.org appears to work much better. Is it possible to use that one in this case?
