Yes deliverability is always going to be an issue. Sending mail from your own domain is really hard. For example, after jumping through all the required hoops to establish trust for my domain I still was going straight to spam for any hotmail address :| I overcame this by routing all mail through google servers. They have a limit of about 2000 messages per day which may be enough to get you going.
