What about owning a domain and using a unique address for each commercial entity?

FOr example, [e-mail], [e-mail], [e-mail], etc.

I have done this for years, but now gmail recipients are rejecting my email as spam. (I've gone through multiple iterations with the DNS configuration at the host, but fundamentally the IP address is tainted other customers on this provider using it to send spam. I shouldn't have to fork up for a dedicated whitelisted IP address just to get functional email). As a result now I have a dedicated @gmail.com address just for those folks and businesses.

I'm surprised the world, and most especially the tech community, embraced gmail so quickly. Yes, it's a great interface, yes, it's free, but from the start they said they would be scanning content and collecting infomation from email content. WHy are we OK with that?

The downside is when I have to reach out to customer support re my account. I can only send emails from my main address.

With Thunderbird you can edit your email address before sending.

It used to be even more comfortable using the "virtual identity" extension its author gave up maintaining it after Thunderbird 68

Fastmail supports the ability to send outbound mail from the email address the mail was sent to that may be of interest to you.
