How hard is replication across servers with just debian and qemu? I’m honestly not super great on linux knowledge. I’m a Windows sysadmin by trade, with maybe 10-20% linux. I run a few Ubuntu server VMs at home and some RHEL at work. So I’m looking for something as easy to set up and well-documented and supported as possible. Proxmox just seemed like the “industry standard” for selfhosting, but I was also looking at Unraid (which is supposedly better at storage and less good at virtualization) or even ESXI, but I didn’t want to get into the VMWare payment bubble if I needed anything more than a simple host.
If they’re using a service to send the emails, like SendGrid or Mailchimp or something, that Unsubscribe survey is actually hosted by the email sending provider, and the more people that mark the email as spam or use the “I never signed up for this” option or similar, the worse it makes the user of the mail sending service look. If they used Sendgrid for example to send a mass email to 10k people, if more than 5% Unsubscribe or mark as spam or use the “I never signed up for this”, the company might get their account locked down by Sendgrid until there’s an investigation as to why they sent spam.
