Hi all, I'm about to start an email campaign and am trying to optimize my account for deliverability. I've heard of MXToolBox, SendForensics, and Mailgun. Any recommendations?

I'm not a tech guy, but I was able to set up my SPF, DKIM, and DMARC. Still other things I can't figure out, like I'm on a blacklist because my IP has a "bogon" (Comcast was no help!). Advice?
