Potential scam

[gabriellabinyon1]

I'm selling an iPhone, the person has bid which I've accepted then they message to say they're using an eBay business account so need my email to put in the payment reference? 
Feels like a scam as not sure why they'd need my email... thanks

There is no need for seller to have your email,tell them that as they pay eBay not you they would be better using the item number as a reference if they need one.

Edit:

Just one more thing please send the phone using RM Special delivery the last thing you want is Evri leaving it on a doorstep and it going missing.

That sounds like a SCAM  buyer wanting your email to make a fraudulent payment.

If they haven't won the item yet then cancel there bid and block them.
