I think it has limited usage. Doesn't work w/ all servers eg: www.chess.com. It's useful for unidirectional application whereby server sends notifications outbound. It doesn't work w/ in reverse direction or bidirectional application.

Simple tool to get rid of or avoid spamming your email ID.

Very limited, not user friendly, hard to implement. I uninstalled and won't be using it.

It's nice extension ! But I got some errors sometimes like : "We are currently unable to send email to ⁨****.****@outlook.***⁩. We received a ⁨soft⁩ “bounce” from your email provider when trying to forward emails to you. This can happen if ⁨Relay⁩ couldn’t connect to your email provider, or if your mailbox was full. We will try again on ⁨5 oct. 2021 09:05⁩"
