20 Telegram Alternatives to Chat With in 2024
Slack works more like a forum than Teams does – falling somewhere in between a forum and a chat software. It lets you organize discussions into different channels, as well as by thread. You can invite others into a thread by @mentioning them, and it lets you add lots of different types of content. Slack works really well for 1:1 audio meetings, “huddles,” that give you the...
Why we switched to Mattermost

CTemplar Email Shutting Down – Try These Alternatives
In a major blow to email privacy, a court ruled in 2019 that the private email provider Posteo can be forced to log user IP addresses for government agencies. Of course, this paves the way to even more logging and the erosion of privacy. ZDNet covered the situation in this article a few years ago.
Have a private email account
Use Fastmail, Posteo, Mailbox, or any similar service where you actually pay $1-$3 per month and in return get a completely ad-free spam-free wonderful email experience.

  • Poste.io – Complete Mail Server
    Ah, whoops, based on that logo, I mistook this for a "Version 2" release of the venerable https://posteo.de/en What advantages does this have over just running RoundCube myself? The things listed on the pricing page seem fairly superficial. - Source: Hacker News / about 1 year ago
  • Ask HN: What email service should I use instead of Gmail?
    I have been using https://posteo.de/en from many years now. They are ad free, secure and an affordable alternative. Their web interface is poor but not a problem for me as I use email clients on all my devices. - Source: Hacker News / over 1 year ago
  • Looking for Email Service Recommendations
    I recommend Posteo https://posteo.de/en . Nothing special, just a simple, straightforward email provider that does what it says (including respecting your privacy). It’s cheap (1 Euro per month for 2 GB, and 25 cents for each additional GB. I’ve been using Posteo for years and have never had any problem with spam filters. - Source: Hacker News / over 1 year ago
  • Riseup.net v/s Posteo
    Posteo is a legitimate online service, the technical particulars of which you can examine in detail by reading their website, which has extensive technical help. Source: almost 2 years ago

    There are sane email providers who do exactly this, for example Posteo — see question "Is there a spam folder" here: https://posteo.de/en. - Source: Hacker News / about 2 years ago
