Steven,
I registered for Cloudflare too, and I was finally able to change my DNS settings! Now I am almost all set with SendGrid, including the SPF/DKIM options through the Sender Authentication tool. I still need to do the DMARC thing though. But, to this point, I am still unable to send or deliver any post-sendgrid emails yet! I think I made serious mistakes testing with nonexistent emails before, and when a few of them went to my junk folder (before I tried SendGrid), I erased them instead of moving to the inbox (to tell the ESPs that they were not spam).
I believe that my problem is now not so much technical (thanks for your help), but of domain reputation and “deliverity” (or something like that) issues, with the email service providers, especially Yahoo and Gmail. I am now taking some “academy courses” (as they call it in the SG site) to improve my domain’s reputation. It will take more like an art type of skills than technical prowess. I am moving slowly, but still moving….
Thanks again for your help :)
CMC
