Mailerlite has threatened us with a fate worse than death if we don’t authenticate and validate our websites. What they’re talking about is making them come from some other location besides a free email server like gmail.com.
My alter ego puts out a newsletter once a month (or so), so we have been scrambling to get the emails put into place. An authenticated email would be something on the order of author@author.com – from the website instead of from a free server. See the difference?
Seems that free servers like gmail.com have been ending up in people’s spam folders instead of being seen and read. The AI’s that handle that sort of thing have collectively decided that if you have a free email account, you are a spammer. So the way around that is to have a verified, authenticated website with an email account. It’s a little complicated to get this done, but supposedly it’s worth it.
