Something like, "if you don't pay for a dedicated ip, but have been a non-spamming client for a month, we move you to a higher-rep ip address pool"?

I tried using Sendgrid and was surprised to find out that unless you buy an expensive plan, then: * You get IPs from a shared pool, and the reputation is nowhere near guaranteed. In fact, many of my mails were blackholed or rejected. * The "bad" IPs that were used by someone for spamming are not immediately removed from the pool, so you will encounter them. The net result for me was that Sendgrid is not a solution fo…
How can you check if an IP is good or spammy? It would be nice to get an elastic IP in the cloud, test it for spamminess, and give back the bad ones. Catch and release fishing for IPs.

Neither, though, helps with checking if one of the big providers, like Google, would not like your IP. For those, you have to send an email and watch/parse the SMTP error responses.
Do you have a system to prevent trusted users from being given low-reputation ip addresses without them having to pay for a dedicated ip? Something like, "if you don't pay for a dedicated ip, but have been a non-spamming client for a month, we move you to a higher-rep ip address pool"?
Now if only there was a decent self hosted alternative to MailChimp.

From personal experience, if you're not jumping straight from no emails to a million an hour, your mail setup is good (SPF/DKIM/etc), you're not reusing a IP address that was sending spam last week (so be wary sending from cloud servers), and you aren't actually sending spam, then you can send from your own infrastructure just fine.
Until recently I sent newsletters from our own infrastructure and I agree that it's doable, but: - You have to ramp up sending from new IP addresses VERY slowly if you want to avoid getting grey / black listed by Yahoo and AOL, this makes it quite a tedious process - Make sure you also have rDNS set up, Gmail uses it as an important quality signal - Accurately handling bounces is a bit of a nightmare because each mai…
Until then, all is fine I agree.

In years past, many RBLs would categorize IP Addresses by type. e.g. dynamic IPs assigned to DSL/Cable subscribers. This would enable a receving SMTP server to check if the email came from an ISP subscriber, rather than an email server. If so, it was usually a good guage that the email was "spammy", because it was sent by a subscriber's infected computer.
In this sense, it was (and may still be) possible to simply block, or at least score differently, email from any/all AWS Elasic IPs.
This seems to be the software behind appmail.io[1], a service just like mailgun and sendgrid. [1]: https://appmail.io/
> Postal was developed by aTech Media to serve its own mail processing requirements and we have since decided that it should be released as an open source project for the community. It was originally launched by us as AppMail but renamed to Postal as part of making it open source as we felt the name was more suitable.
