I've run my own mail servers for many decades and have never had any deliverability issues. I've also never used bargain basement cloud VPS services with horrible reputations.

The best way to ensure a good reputation is to obtain your own address space from a RIR. Barring that, you need to choose a provider with a decent reputation to delegate the space to you.

There is the slight problem that RIRs ran out of (v4) addresses almost a decade ago.

Not true, at least for ARIN. If you have an IPv6 allocation, you can obtain one or more IPv4 /24 allocations, so long as their stated purpose is to provide IPv4/IPv6 compatibility (e.g. for dual-stack services or NAT): https://www.arin.net/participate/policy/nrpm/#4-10-dedicated...

How does one do that? And what are the costs involved?

From your HN profile, I see you're in Brazil, which is part of the region IANA has delegated to LACNIC. Per [0], LACNIC has further delegated numbering authority in Brazil to Registro.br.

Following the links on that page (or performing a simple Google search) leads one to: https://registro.br/tecnologia/numeracao/como-solicitar/

Looks like I need to become a literal ISP then.

Before I even start this bureaucratic process, I need to create an actual organization. Then I need to be assigned an ASN. Only then I'll be allowed to beg them for IPs. Once all that's taken care of, I need to tell them things like what the IPs will be used for and what my infrastructure is. If they like my answer, then they'll approve my request and finally tell me what the prices are.

Wow, that's pretty crazy, compared to the US. I paid a one-time fee of $50, then $262.50/year for IPv4 block + IPv6 block + ASN: https://www.arin.net/resources/fees/fee_schedule/

I've been through the process about 10 times now at various companies, and the paperwork (at least for ARIN) is no more difficult than what would be expected to justify IP space from your typical ISP. If anything, the ARIN folks are more responsive and technically competent than your average ISP support agent, which makes the process easier.

This seems like a lot of TODOs for something I’d rather just pay a few cents for
