Solution for mass mailing

Hello,

Yes I know there has been a few threads about this, however none of the answers seem to fit me.

The emails I have are all buyers, so up to 0.1% complaint rate(altho right now 0.02%) and 2/3% bounce rate.

I'm in need of sending at least 30k emails a day and land in inbox.

I'm currently currently running interspire with mailgun SMTP to mass mail.

However the problem is poor deliverability, I'm hitting a lot of spam folders.

I used mandrill in the past and it was working like a charm, however their strict policies got me banned eventually.

So I got a couple of questions, could anyone suggest a better software than interspire? As mine seems to be buggy.

The second question would be - what SMTP provider to use that has good reputation and tolerates non spammy(these lists are not bought, they are legitimate buyers, might not expect my emails, but i'm sending same niche emails, not some dating offers or something) mass mailing.

Anyone could suggest anything?


Thank you.

The only legit way is to have an autoresponder,but i`m sure you can`t add a big email list in bulk.

U are using scanned or hacked SMTP?

I'm a newbie too but best for mass mailing I think is setup a SMTP on Virtual Private Server (VPS).
Not sure how-to, cause all tutorials are outdated.

Opened a thread about this.

I've tried it few months ago, so still have lots of commands of Centos 6.3 saved in .txt.
How to install Postfix, or Desktop, but still missing lots of pieces in the puzzle and not sure what to use and what to use not.
