I’ve read this with concerning frequency, was SPF/DMARC/DKIM all in order? I also have to question if it was a matter of IP reputation, since shared hosting IP ranges are usually pretty thrashed.

I rent mailbox services (for a custom domain) from a local ISP and don’t have problems with deliverability as such.

Seconding this, while I have the option for multi-gig at my address, I don’t have the need, once you get around gigabit upload speeds life is fine.

I can upload hours of uncompressed gameplay to YouTube in under an hour, and that’s limited mostly by their ingest speeds (≈300Mbps) and not my end, so that’s plenty.

With all that said, the option for consumers is great, I’m thankful I have that choice, wish more people had it too.
