I am a newbie here. Thanks to everybody for all the tremendously helpful information. It is sad that there is almost nowhere else to find honest information about choosing and working with a web hosting provider.
I am testing a couple web hosting providers I found on this website.
I would like to be able to use my web hosting provider for email, but I want to minimize the risk of my emails going to spam.
My question is how much email deliverability is it fair to expect from a shared web hosting plan? A couple places have issues with validation of the server through rDNS and smtp banners. One doesn’t even support DKIM, which seems essential in this day and age. A couple places use mailchannels, which seems to help, but, contrary to what I was told by their support, is not a complete replacement for DKIM.
I get issues with email going to spam folders on my Gmail, Yahoo, and Zoho accounts. I get complaints about server configuration and validation from test websites, such as mail-tester.com (which was recommended to me by one of my email providers, protonmail.com), analyze.email, mxtoolbox.com (recommended by one web hosting company), and isnotspam.com.
It isn’t really an email thing, but mxtoolbox.com pointed out that it wasn’t great to have both one’s name servers in the same subnet (or whatever they called it.)
It adds expense to use zoho.com or protonmail.com for email, but perhaps it is unavoidable? Perhaps, I am asking too much of the web hosting providers?
I have not named the web hosting providers, because I am not looking to disparage them at all, if this is a PEBKAC error on my part. (If anybody from one of the web hosting companies reads this, please be assured I am trying a couple, so I might not be talking about your services in particular.)
Just to explain my background: I was in IT a couple decades ago, but Internet and web hosting were not something I ever focused on. I did database management and later database architecture and development. Right now, I am pursuing this stuff as sort of a hobby. I happen to like puns and wordplay, though, so I have bought way too many domain names, leaving me with the desire to put simple websites on and set up email for most of them. I won’t be generating much traffic and I won’t be sending more than a few personal emails.
