No. An email client is a special program on a computer which you use to access your email. In most business situations that program is still Outlook. For home computer users it was, for a long time, most commonly Outlook Express but then Windows Live Mail came along, followed more recently by the Windows 10 Mail app. (There are also non-Microsoft programs for the task, with the best-known being Thunderbird).
Such programs are totally independent of web browsers (such as Internet Explorer, Edge, Firefox, Chrome and Opera). If you normally access your email via your web browser (i.e. you go to a web page and log in from there) you CAN'T use things like 'Send to Email' or 'Scan to Email' because those things rely upon you having a special email program (from my first paragraph) already properly configured on your computer.
If you want to scan a document and email it you need to do so in TWO separate stages:
Firstly, forget about email altogether. Simply scan the document and save it as a file on your computer. (You'll probably want to use .jpg format if you're scanning a picture but .pdf format if you're scanning a text document).
Then log into your email account in your usual way and create a new email (just as if you were only sending text to the recipient). Look for a button labelled 'Attach', or similar. (Some email services use a paperclip icon). Click on it. Navigate to the location of the scanned file you just saved. Double-click on that file. You'll then have added the file as an attachment to your email, so that the recipient will have access to it. Send your email as normal.
