Sharing with email using Jetpack plugin stopped working

My blog at https://realestateblog.condoscafe.com/ uses the Jetpack plugin. All sharing buttons are currently working except for the one that allows users to share via email. When I use the share email button it gives me a message that the post was shared but I do not get any email message. Thsi was working a couple of weeks ago and suddenly stopped working.

Any help will be appreciated.
