Warum nicht mal jemanden einfach drücken?
Ist zwar persönlich, kommt aber sicher gut an (besonders, wenn unerwartet).

Hi,
also many greetings kann man nicht sagen. A lot of greetings noch am ehesten, aber einfacher ist dann wohl best wishes oder auch sincerely.

nur "greetings" is am besten, glaube ich.

Greetings,

"also many greetings kann man nicht sagen. A lot of greetings noch am ehesten, aber einfacher ist dann wohl best wishes oder auch sincerely."
@Gunther: Pardon??

You come across "many greetings" a heck of a lot more often than "a lot of greetings" - that sounds plain weird. "Sincerely" is rather formal, something babblebrook wanted do avoid.

More informal complimentary closes can be things like
best wishes
regards
hugs (& wishes), as given by Bama Torsten
take care
all the best
best
so long
etc.

Choose one of Satori's options. Contrary to what many Germans believe, we do not say "greetings" as a closing.

I agree: no "greetings" as a closure. "Greetings" can be written on a postcard, etc.

Not "many", "lots" etc. greetings.

Cheers,

I disagree for "cheers" because IMHO it doesn't have this 'greets' character as the other suggestions above.

I disagree with "cheers", if anything. What is a 'greets character'?

'cheers' is okay for a very informal ending.

I beg your pardon.

'Greets' is a very common shortform for 'greetings' in AusE. It's like 'congrats' for 'congratulations' and so on. I wouldn't use cheers here because it has a slightly different meaning IMHO.

And the slightly different meaning is? Could you explain that a bit, please? And what would you say, by the way?

I only associate cheers as alternative ether a) for 'thanks' or b) for an exclamation, especially often heard at New Year's Eve while clinking the glasses.

I'd probably use simply "greets" or "lovely greets" depends on to whom you address and what's running first through your mind. For example I never ever wouldn't sign a letter with 'hugs and kisses', it's more a women thing.
