What is an email alias and how to create one

Thank you for the explanation

Thanks for making this video BUT, I'm having a really difficult time with the audio quality. Just like Gillian's comment below, I too am having great difficulty understanding the vocals.

So your telling me that an email alias is like a po box. If you wanted to send mail but you didn't want to put your personal address. Expect it's for your email?

Hi ... just quick feedback... your voice is not very clear in this video, maybe to close to the microphone... not sure why... but I clicked in and out because it was so disturbing, and then I came back to leave you this message, hope it helps

Can i lower my email spam score with this?
