How to reach buyer with question before shipping when email incorrect.

[vintagenorth]

I need to reach a buyer with a question before I ship. New guest buyer. She doesn't respond to emails sent through eBay messages and the email address she gave on PayPal is undeliverable. Does this email (comes back as undeliverable) count as an "incorrect address". I really think she still wants the item but I don't really want to have to make a long distance phone call to her either.

I did find this on eBay. Would it apply here? Not sure if a user also applies to a buyer.
Invalid and Dead Email Addresses

A user’s account must always have a valid, working email address so the user can be contacted by other eBay members and by eBay. If a spam filter prevents messages from eBay or its members from reaching an account, the account is considered to have an invalid email address. Members need to take steps to ensure their account is valid and working.

Violations of this policy may result in a range of actions, including:
Listing cancellation
Limits on account privileges
Account suspension
Forfeit of eBay fees on cancelled listings
Loss of PowerSeller status

Members who get an error message when they send a message to another user’s email address are most likely contacting an invalid or non-working address. Members are encouraged to report this by using the Customer Support link at the bottom of this page, and including the error message in their report.

So, I just read that a person using a guest account can not access their "My eBay" until they register as a user so obviously can't read their messages. I guess I will have to call her tomorrow evening; I'm pretty sure she is at work during the day from the email address.
