I'm Confused About The Inbox Inquiries of Buyers

[suprmarketplace1]

Question,
When I receive inbox inquiries from potential Buyers, is there are a way to determine whether:

They’re asking about my gig as advertised on Fiverr (a $5 gig)
OR
They’re asking about my services for so I can make a Custom Offer (a $XX gig)
.

When I’m inboxed I can’t tell the difference.
I’ve mistakenly talked myself out of lucrative opportunities because I quoted them $5 before I realized they were looking for something much greater.

When someone messages me, I automatically assume it’s specifically for my advertised gig.(Maybe it’s because I started on Fiverr before Custom Offers were introduced).

I’m not seeing anything differentiating them. . Am I missing something Fiverr?

Thanks!!
