In order to provide you with a variety of compatible matches, we recommend your profile to other members whose criteria you meet.
It is highly likely that they want to get to know you better, and you may therefore receive a smile or message from them. These are your Profile visitors.
In addition to recommending your profile to others, we also promote your profile in our "Have you met..." feature. This feature relaxes your search criteria, allowing you a wider range of compatible matches. If you appear on a member's "Have you met..." list, they may initiate contact with you too.
As such, you may indeed receive a message from someone that does not quite meet all your criteria. However, every match is compatible, as per our matching process, so it's worth responding to see if you hit it off.
You are, of course, at liberty to delete a match if they really do not meet your expectations. The profile will be removed from your “Matches” list and they won’t be able to contact you again.
That said, even if at first glance someone does not seem like a likely candidate, don’t be too hasty in deleting the profile. It’s worth responding because communication is the first step towards finding love!
