I have read about two dozen threads on BHW and this is not clear to me. I am sending 1-2k emails a day, very targeted, customized to each recipient and I'm confident that my spam reporting rate is very low. I currently send out through a custom SMTP software after connecting to a proxy from squidproxies via Proxycap. I know this is working to hide my IP since the Google Apps accounts I sent through's "most recent connections" area shows my proxy IP. I want to confirm with an expert that this is a proper way of doing things. I'm concerned that this volume of emails coming from one proxy IP is not good enough. Also, if I were to rotate proxies, what would be the best practices? I'm thinking that having as many email addresses sending out as possible and rotating proxies weekly and email accounts monthly would be ideal to maintain a high deliverability rate. Thank you in advance, ladies and gentlemen.
