Discovered Reverb when searching for a voice message tool for my business partner that has a handicap, and can only write using his mouse with the virtual keyboard on the computer, so it takes a while to write long messages. It works extremely well, and you can use it for more than just email as Reverb provide you with a link to share.
Use the Reverb Record website (https://record.reverb.chat/), or get the Chrome Extension (https://chrome.google.com/webstore/detail/reverb-record-share-your/lcblhgplmpgpmnmnochlcdbickjnemfe) to record in email drafts. Everything is totally free and there’s no required registration or sign up.
