- [R1] mail.com Wow! WTF: I have been using this service for work for several years and started using it for my personal e-mails as well. I loved the multiple e-mail addresses, very handy for splitting e-mails of by groups. I use the office part as well. Loved It. So much so I have all my documents and info in there. Well, Come this past Monday I try to log in from the same phone I have been using since I star
- [R2] mail.com Perfect Mail Management: This package allows you to manage your digital identity to a very granular level. Dig in and explore the potential.
- [R8] mail.com Very good mail app.: This email client is fantastic. I haven't found another client that shows such a variety of domains to choose from, which gives a lot of freedom to be creative with your selection, which I appreciate. It offers all the functionality I need and the iOS app is super clean, which I love. I highly recommend this for anyone looking for a free email client that looks great and is ea
- [R9] mail.com Needs. Revamp: The app is very slow to display the emails. Very limited and primitive search function. Quits if there is a large number of emails in the “deleted” folder. Overall, after so many years it needs revamping and improvements Maybe at that time worths the paid subscription.
- [R3] mail.com Website is OK, app is horrible: Emails take forever to load forever to open and when you decide you don’t want an email you have to delete it like five times before it actually goes away. Deleted emails just keep coming right back.
- [R19] mail.com Text Even Smaller in Latest Update: Whose “bright idea” was it at Mail.com to make the overall text of the app EVEN smaller than it already was?!? Now I can’t even use this app anymore!!! No one can read the tiny print of all the app features. Inboxes etc!
- [R6] mail.com Its below average NOW: It used to be fast with very quick customer support. It has gotten slower over time even with my fast fiber internet connection, if I need help it takes a long while for an answer. For a service I am paying for I expected different so I am looking for other options next year . I gave it 3 stars because it doesn’t have any spam issues which why I chose it for!
- [R7] mail.com Locked me out of account: I had very important emails and pictures on this app and for no reason I was blocked from using the account. All my important emails gone!
- [R16] mail.com The least performant email client ever made: The same hardware that can run an 8B LLM, when utilized by this application, takes ~1-5 minutes to search for an email. The app is unresponsive, regularly crashes, and is overall terribly optimized. Routing emails to another client requires a paid subscription. Only use if you want a really cool @ handle (like @engineer), caveat emptor
- [R20] mail.com Review: good app, reasonably priced (it's free!)
- [R4] mail.com Good luck if anything goes wrong!: My email recently stopped working. Nothing happens when I hit Compose, Reply, or Forwards. I have run through every trouble shooting measure from the mail.com site and from Google and ChatGPT. It still doesn’t work. I’ve requested assistance from mail.com twice and twice ignored. Guess it’s time to go to gmail…
- [R22] mail.com Terrible latley: When I first started using the service four years ago, if not longer, it was reliable. Now it is consistently getting hacked and I can’t even currently login due to an error message. There is no customer support on this no phone number no email nothing. Find a different provider so you don’t get screwed like I am now having to find a new email provider for my business after four y
- [R34] mail.com Customer service: Could not reach anyone at your end to discuss my Oder. Still know nothing.
- [R10] mail.com Locked out: Three times now they've had a glitch that won't allow you to log in. It was all day today and still waiting.
- [R64] Microsoft Outlook Authentication is atrocious: If you use this on mobile they make it impossible to authenticate on a single device, the app tries to authenticate on the authentication app via the authentication app. If you have a meeting to get to on mobile and you get signed out good luck. Also the outlook sign in solution also failed. This process all around is a failure.
- [R70] Microsoft Outlook Richest poor software in the world: The application functions just like any other email application with the added side effect that you will randomly not be able to sign in due to their Authenticator app being complete and total garbage. It will trap you in an endless loop of needing to use the Authenticator app to authenticate that you’re using the Authenticator app so you can authenticate outloo
- [R73] Microsoft Outlook Authenticator App wants to Authenticate Authenticator App through Authenticator App.: I can’t log into the Outlook app on my phone without it going through the Authenticator app. Authenticator app wants me to authenticate the Authenticator app login through my Authenticator app. I can’t use the same app to authenticate my ability to use the same app. Furthermore, there is no number I can call to
- [R47] mail.com Excellent mail system: Mail.com is the most efficient mail system I have ever used! Because they offer the Premium option, the subscriber has the option of avoiding those annoying ads and I have never experienced most of the inconveniences friends have encountered.
- [R100] Microsoft Outlook Ads??!!: As if we are not all bombarded with enough ads in our daily life and our inboxes… now we are subjected to ads at the very top of our email lists every single time we open our app!!??! Absolutely disgusting money grab tactics. Shameful.
- [R106] Microsoft Outlook Ads in Email???: What’s next? Ads on you login in screen to your phone? No wait, embed a live link to an ad on every picture you take! That would be great. Seems like they keep cramming ads down your throat whether you want them or not.
