Dedicated IPs aren’t great because they’re completely untrusted. Better to sign up with a smaller email provider than mailgun/ses

SES warms up dedicated IPs for several weeks by using them for regular SES traffic during the warmup phase: https://docs.aws.amazon.com/ses/latest/DeveloperGuide/dedicated-ip-warming.html https://docs.aws.amazon.com/ses/latest/DeveloperGuide/dedica...

I work with Twilio SendGrid. What do you mean? IPs are the de facto way that reputation is tracked and a dedicated IP’s trust is based on your sending habits. How would a smaller provider be better? The only thing that I can think is similar IP ranges can also influence delivery, so you may want a dedicated range for transactional email. I don’t see smaller providers as able to do that.

  A new dedicated IP is unknown and some providers will automatically treat it as untrusted and give it a lower score. A smaller email provider can give you a shared IP that has other users and is therefore already whitelisted. Provided the email provider has good anti-spam approaches (e.g. enforced DKIM verification), you should have better luck with that shared IP over a dedicated one if you only send a few thousand emails a month.

    ah, I see what you are saying. Better shared pool management by the larger senders would help, but a smaller sender should be able to more aggressively protect their shared IPs; I agree in principle. This is extra important for infrequent sending. I still contend that a dedicated IP is superior for deliverability reputation as long as you are sending enough email. For a brand new (to you) dedicated IP, it will need to be warmed up (gradually increase the amount of traffic it sends). There are automated and manual processes to accomplish that, including "pre-warmed" dedicated IPs that were previously in a "good enough" shared pool.
