I don't know if people here would know whether buyers would prefer email or a phone call since they're people just like you and I. I don't think because they're buyers that puts them in some kind of category for communication preference. However, that being said, I think it's probably wise to do both. If they're larger wholesalers then they're probably busy people. A phone call might get missed or they may not have time to list all their criteria on the phone. Email is convenient because they can answer it at whatever time suits them. So you may just want to call them to introduce yourself and ask if it's ok for you to send an email about what you can do for them in their hunt for deals and ask them to reply with whatever criteria they have. Just my 2 cents.
