If you've read the other reviews about Mail.com, I hope my experience will convince you to not only reject any offer to use their services, but to also let others know that this is not your average, every day, "bad" mail client service. I'll be submitting links after I'm done.

When I first signed up with Mail.com, I was trying to find a substitute for "Outlook," and I won't bother about the reasons, except to say there was an article detailing alot of the bad things about Outlook that I agreed with from experience. Bottom line -either you like it or you don't; if you don't, you go find something that works for you. But, keep in mind, that you'd best do your homework, especially if you're looking for a place to send and receive your public, private, personal and/or professional email.

Anyway, when I signed up for a free account, it was completely different from what it is today. I'm not sure who owned it at the time, but it looked a lot like a knock off from "Squirrel" or "Cube" with all the options listed to choose from - how to set up, how to choose a name, how to delete, save, forward, archive, etc. There was a listing of all the mail names you could choose, and - most important - there was the ability to delete, move, archive, download your mail or folders, without having to ask permission - only to be denied. It was simple, direct, and to the point, and I didn't even mind the ads, as I had enough protection to not be worried about viruses/malware or having to click something twenty times before getting to my mailbox.

Then a few years ago, I get the email telling of changes. I wasn't worried, but I went over to check it out. It was at this point I realized they had been changing it all along - slowly, but surely. Links and directions began to disappear. I couldn't pull up the area to change my email address, phone number - whatever!

What scared me the most was that outside of the default account I had, I never connected my Outlook mail account to any of my other folders, yet, I go over there one day and all my folders are there! Including the ones holding sensitive information that I knew I could keep in Outlook, but would never place anywhere else, yet it was sitting in "MAIL.COM." I was pissed, because the intrusion I was convinced Outlook was guilty of, is what Mail.com had become - practically overnight.
I sent them an email, telling them that I wanted to archive my email for a download. I didn't tell them that I resented their new service, figuring it best to walk lightly at first, because any company that would dismantle all the tools and links benefiting the customer - with or without good reason - and then not providing the means to act on such a decision, should be approached carefully, if only to gather information.

The response I got back was simply one of an apology, and a statement that they don't provide that service any longer, but I was welcome to forward to my heart's content (No, they didn't write that, but it sure felt like that's what they were saying). Well, that's all I needed, and my email informed them I wanted to cancel my account and needed to get all my mail so I could delete it from the system - or at least give me the comfort of thinking could, anyway- and wanted to do it as soon as possible.

They wrote back a few days later with, - and I paraphrase - "We're working on our servers right now, and had to remove that feature. However, if you want to close out your account, please write and tell us. We'll do it for you, and make sure that all your emails will be deleted as well." I had to read this twice. I've been playing with computers since the 80's, and I'd never heard anything like this concerning email.
Did I mention that at this point, Outlook was looking pretty okay, and a part of me wanted to send them a hallmark card with a an apology for being so judgmental?

I shot off another letter threatening to report them, and of course, they didn't respond. Here's why: They don't have to do anything or comply with any policy, because THEY AREN'T AMERICAN.

In fact, what they did to me, and what you've read so far in the posts? Well that's nothing compared to what they're doing globally. Just type in "Mail.com" over at Wikipedia, to get a glimpse at who they really are (Please don't go into the whole, "You can't trust Wikipedia. Of course you can trust them. You can trust them far enough to know what direction to go for more validation or proof.).

If this post is allowed on this site, you should get the word out to everyone who is thinking about signing up with them, or is trying to get out from under them.

This company is the ultimate example of why the Internet cannot be run by or in
The control of countries other than the United States. Their tentacles reach far and wide, and right now there a few Internet reviewers looking into the story behind Mail.com (I'm actually a little proud that in one case, research is the result of my situation) I'm hoping they'll check to see if this coincides with Obama's agenda to take the power of the internet, and place it in the hands of a less capitalistic, consumer-driven entity. People are only now starting to realize that Obama's greates talent was distracting America with one hand, while doing his damage with the other.

Anyway, read the Wikipedia article, then do what I did. Go to the search engine and start typing keywords like - Mail.com - owner - consumer complaints - legitimate - bogus - deception. Trust me, keywords can/will take you far, and the sooner you learn how to pull up info on Search engines, the better informed you'll be in the long run. Hell, I knew better than to vote for Obama, but I still checked him out to confirm what I knew to be true.

So, here's the bottom line: If you value your privacy, get out of Mail.com. If you have bank, credit, mortgage - anything that requires your SS#, DL#, phone, home, spousal info - WHATEVER - if you do your work online and are using Mail.com, you are about to become like me - a cautionary tale.
Unless you're paying for Mail.com - a subscription that provides everything that was once free and probably additional perks - all you have send and received on that account is theirs, and here's the kicker:

They can and will shut you out of your account - without warning or reason. Let me say that again:

THEY CAN AND WILL SHUT YOU OUT OF YOUR ACCOUNT - WITHOUT WARNING OR REASON. You'll find this in the article as well.

Look, I'm not naive. I know that collecting info is something everyone is doing. Fact is, if you've never been on the Internet, I promise that five minutes after you sign up, there won't be a social network or business who won't have some info about you. It's the nature of the beast, and a price we all are paying dearly for. All I'm saying is this: It's bad enough dealing with American companies stealing our info, but to have A GERMAN CORPORATION BLATANTLY DICTATE how we use our mailboxes is... well, you know what it is.

I've spent the last week trying to wipe my box out by filling it with bogus info, namely changing email addresses, replacing it with a domain email that had none of my info - mail or anything else connected to it, and then redirecting addresses I want to my new email address which I purchased through a domain hosting site. You can get a domain for as cheap as 99cents and another for 1.50, which is pretty good compared to hosting companies trying to sell the same thing for 14-25.00 and up yearly. I say get the cheap domain, you don't even have to set up the site, but for 99cents, you have a domain and address, and then next year you choose whether to pay the full price for a renewed domain (5-15.00), or you go fishing for another deal that will allow for transferring your domain.

Either way, get out of Mail.com as soon as you can, because they are legitimate in the sense they have the money and the wherewithal to do what they're doing, but they are most certainly doing it for wrong reasons, and let's be totally honest here:

If they're so arrogant as to remove the tools that prevent free subscribers from forwarding, archiving or even deleting folders, I'd hate to think what they're doing to the paid subscription people, all of whom, are frankly paying for them to do what they've been getting away with for the past five years or so.

And for god's sake, don't invest in the apps that claim to make Mail.com better. If they really wanted to improve, they'd give back the power to control the boxes. Period https://en.wikipedia.org/wiki/Mail.com
