… at least not for the domains you’d be willing to sell at let’s say 3 figs to low 4 figs.

Some end users are genuinely clueless but it’s not unusual to see seemingly ridiculous lowball offers turn into low-ish but still decent sales if the domainer educates the person in question.

On the other hand though, it’s highly unlikely that such a lowball offer can turn into a substantial sale, so for your blockbuster domains, this strategy doesn’t necessarily apply.

For lower quality domains though, it might make sense to at least send a template-ish educational reply as opposed to ignoring that offer or giving that person a piece of your mind 🙂
