>Amazon SES shared IP pool isn't better than Sendgrid or Mailgun...Unfortunately not a lot of providers offer dedicated IP option on lower level plans.

I think the main problem I have with SendGrid here is that they knowingly offer a paid product with such abysmal shared IP deliverability out of the gate, then offer no meaningful mitigation except to upgrade to a plan that includes the dedicated IP at a 6X premium, along with features many customers don't need (primarily send volume). Many customers will say "that's overkill, I don't need that send volume".

Very much a bait-and-switch feel to it. If they're going to offer the lower cost plans, then they need to be forthcoming about the disparity in deliverability. Instead, they say vague things like "own your reputation with a dedicated IP", when the truth is actually "12%-15% of your emails may suddenly stop being delivered unless you choose a dedicated IP plan".

Publish metrics and let people choose.
