Folks think that they have 100% reliable access to their email from google? Gmail is blocking untold emails, with no explanation of why, and the sender and recipeint may not even get a notification they have been rejected. This is not the RECIPIENT blocking, but Gmail doing so based on who-knows-what BEFORE it reaches the recipient. I have had no reliability problem or data-loss, with hotmail (20 years, have a paid account now), nor justhost (10 years+, except gmail now more often randomly blocking emails to people I have sent numerous emails to for years). Even if Justhost is originating spam "somewhere", if google's AI and algorithms are so smart, why can't it figure out that email to people in regular communication over a long period (and by topic/content of an email thread, the previous email going thru fine, since they're reading the damned emails also for cripes' sake ) is not "spam" (answer, they really could not care less, particularly from other ISP's). And, if their data is lost, or there is a "glitch", do they think they will ever even be able to get ANY response/action from google?
Why people let google (with google mining their email content itself) and facebook, et.al. mine their personal data to be pimped to anyone and everyone for who-knows-what purposes (not just advertising by a long-shot), currently and in the future, is a mystery. All for something that is "free" (the "customer" being the "product"), when they could spend a couple of bucks a month to reduce/prevent it. Geesh, google even states in their terms of service they can use ANY data for ANY purpose, with no liability, including confidential business communications.
I'm about to start a new tactic on my email, since sending TO gmail is becoming so unreliable, and there is no transparency from Google. I may just set my email to not accept any mail FROM a gmail account, with a message saying that since gmail is randomly blocking my communications to their gmail address, they will need to send email from a different account, and provide me with an alternate account, or call me. Why should people put up with googles' covert, opaque, secret shenanigans because others choose to use their "free" data-mining and pimping "services". I also do not use google as a search engine any longer, nothing but an add, paid-result, and spam-factory itself that takes too much time to wade thru. It's sort of ironic, google supposedly secretly and opaquely "protecting" people from spam, while being the largest spammer (and/or spam-facilitator as it were, reaping huge profits from it) and targeter in the world; google: "...the only "good" spam, is any and all the spam we get paid for, directly or indirectly..."
