Don't expect any suppport from the developer, Bharani Muthukumaraswamy, even if you have his Premium plan. I've been trying to get him to change the email address on my account for months, and his only response was to upgrade me to Premium when I already had Premium! I even tried contacting him on Twitter, to no avail. Oddly, his other website, resumonk.com, allows users to update their accounts directly, but not EmailThis. Obviously it's not a high priority for him.

As for the extension itself, it works ok most of the time. It sends a pretty good ad-free copy of an article to your registered email. It would be more convenient if I could send articles directly to other people, but instead, I have to send them to myself and then forward them. Bharani said he tried this but too many people got spammed. His server was down once, and the extension briefly stopped working a couple months ago, but he got it fixed again.
