Migadu

A friend has made me aware of this one and called it his favorite, but I don't like it for a few reasons:

• It's paid - that alone does not kill it, but free should be prefered
• You must pay for the whole year ($19) upfront if you want the Micro plan, which is the cheapest. The other plans are extremely expensive and I'd say, not worth it for a simple E-mail provider.
• You must contact them personally if you want to pay with Bitcoin, but at least they do support the option
• They don't provide a domain, so you must buy your own which is an additional cost
• The Micro plan allows only 20 outgoing messages per day, which is kind of low. To be honest, I never reach it with my own E-mail usage, but depending on what you do, 20 might easily be too little.
• They require giving them your real name to sign up
• They require an existing E-mail account; temporary ones are banned
• They store your outgoing messages for up to 30 days
• They store your IP addresses but claim they are "anonymized" - you are not informed of how that is accomplished, however.
• Inventory data is stored for up to two years, and possibly more if some unspecified legal stuff applies.

So, Migadu is a paid provider that needs a domain and whose privacy is not that great. At least they allow Bitcoin payments and support mail clients. Overall, I'm not impressed and would much rather go for Disroot, RiseUp or Posteo / CounterMail if money is not an issue.
