Time Frame Between Emails Without Getting Red Flagged

Hello, is there a particular numbers of emails per day sec, minute, hour, day that is recommended to send without getting blacklisted?

I have my own servers SMTP/POP3 info and I have a pretty good email marketer program as well and I currently have a whitelisted I.P. with my server but Im just wondering if there was any certain amount to send without getting blacklisted. I need to send out about 400,000 emails to my current member's who have all opted in to receive monthly newsletters and although I want all of them to get the email, im in no rush if its gonna get me red flagged so im willing to keep the program running for a month straight in order to get my emails there.

 

Since its opt in.
I would recommend you use aweber coz you don't have to worry about whether your email get flagged as spam or not.

 

Thanks for giving the great solution.. I was also thinking about that..!!

 

I understand that. Im familiar with Aweber but the reason I ask is because I have my own server, a whitelisted I.P. and I would like to send my own emails without having to pay for an extra service since I already pay close to $800+ per month for my current server so I just want to utilize what I do have so I need info. on what email companies accept as far as emails per day so that way I don't exceed that and get my server blacklisted. All my emails are Opt-In's from my current site, I just wanna be able to send to everyone and save money at the same time.
