usage of till now and until now.

[subhajit123]

What's the difference between these two sentences?

'I have not received any emails until now' and 'I have not received any emails till now"

Does the first sentence mean I have now a received an email.

 

[Raymott]

They mean the same thing. One is simply a version of the other. ('Till' is less formal).

The sentence suggests that you have now received an email. Otherwise, you'd say "I haven't received any emails yet."

Thank you Piscean and Raymott. If I say "I have received two messages until now.', does it mean I have now received more than two messages?

'Until' is an ambiguous word.

'if something happens until a particular time, it continues and then stops at that time'—quoted from http://www.ldoceonline.com/dictionary/until
'until
happening or done up to a particular point in time, and then stopping'—quoted from http://www.macmillandictionary.com/dictionary/british/until

It is uncertain whether it stops at that time or after that time.
