This would be a massive help in marketing a property. If we get a price reduction or would like to send an update, there is no way to do this other than having to go through and add each email to a mailing list.
Agents often do not have time to go through and do this process - especially when they get dozens of enquiries on each property and usually call the buyer instead of updating through rex. I have had a response from support about this, and they said that it is because some emails are spam, but that does not really matter as they will just bounce or get deleted. We are missing a massive opportunity to have good contact and interaction with buyers that all other CRM's provide.
