These emails are sent to you as an alert for your Matches, recent visitors, Interests, etc. & help to accelerate your matchmaking. 

For now, we don't have an option to stop the emails The only way to stop them is to delete your profile but that means you will be away from community-specific matchmaking. While we are looking into having this in the future, you may ignore these emails if you don't find them useful. 

If you still wish to delete the profile, you can do by following the steps in the Delete profile Article 

You can also find the delete option under "Settings" on the Home page.

Note: emails/SMS will stop after 48 hours of deletion.
