Don't buy the “domain + e-mail” subscription from #Strato.de:
➡️ They disallow you to use their mail server (which you pay for!) if you choose to use a third-party name server.
➡️ Also, you can't set a custom TTL for your DNS records (at least I found no such option).
➡️ Recently, their customer login was unavailable for hours (so it was impossible to modify any DNS settings).
