Spam testing and configuration for Inboxing bulk email campaign

I have a server with interspire and SES setup. I have done the DKIM setup and SPF setup on a subdomain. But still more of my mails are going to spam.

I only need to send 2k to 3K mails a day, but I need them in 95% + in the inbox . Need someone to check the configuration and troubleshoot the issue to get emails going successfully.

This is urgent!
