HomeAway protects your privacy and helps prevent spam and phishing by making the email addresses anonymous using a “@messages.HomeAway.com” email address (e.g. THA123456@messages.HomeAway.com) during the initial email exchange between you and interested travellers.
 
Anonymous email addresses hide the real email address during the initial email exchange between owners/ property managers and travellers. This protects thieves from sending multiple inquiries to get a response from an owner or property manager at which time they 'steal' the email address and start communicating with travellers directly in an attempt to have the traveller send payments to the thief.
