How long is too long to wait before responding to a JDate email? Ideally you would respond within 48 hours — the same amount of time that is acceptable when you’ve received digits from someone who you met at a bar or elsewhere. If there’s a reason that you can’t get in touch earlier, then apologize for the delay and make sure you sweeten the pot by responding with a charming email.
It happens sometimes. Perhaps they were considering another JDater and wanted to give him or her a chance, and thus ignored their inbox until they were available. This is the usual reason why people don’t respond right away and it’s perfectly acceptable. That said, don’t actually ask whether that’s the reason; simply respond that it’s okay, ask your match how they are doing, and then let the conversation go from there. If that response takes a lengthy amount of time again, then you may simply be communicating with a flake or a player. If they reply right away, however, and it’s an engaging email, then let the delay go and move forward.
Timing is everything with dating. Are you going to give up on someone because of a few weeks?
