Hello, and thanks for your question.
Can you please elaborate a bit on your problem? Are you trying to send email to a match.com address and it is either causing a bounce back error, or just not sending at all and not providing any errors?
If you're talking about being logged into match.com and trying to send an email directly through their service, possibly your subscription has lapsed and you aren't allowed to send any new messages? You probably will want to chat with match.com support to find out what the issue is.
