Also, it may be a good idea to choose a professional SMTP service to send 10.000 emails per week. In fact, if you use a common outgoing server (like the ones provided by Gmail, Hotmail or Yahoo) you will probably run into some deliverability problems.
As antispam filters become more and more severe, only a dedicated SMTP service can guarantee that all your emails are correctly delivered without getting lost or rejected.
