Is it polite to use "how about..." in formal message or it will suit for close relations only?
What should I use instead for stranger or boss?
UPD: Example: You have just provided me with your phone number. How about e-mail address?

I think "How about" is very informal; it results in a sentence fragment. A formal rephrase of "How about we go to the meeting?" is "Why don't we go to the meeting?" Since we don't yet have an example sentence from the questioner, another test would be "How about lunch?" which would be more formally phrased as "Why don't we go to lunch?" Or, if the interrogative is not necessary, the declarative "We should go to the meeting!" and "Let's go to lunch!" are also good formal alternatives.
(You'll note that I am using contractions in my "formal" examples; that's because I think my example phrases are professional, and saying "Why do not we go to the meeting?" is just awkward.)
Not disagreeing with others, but "How about ..." is rather a pushy phrase. Would I use it to my boss? yes, because I address him informally. A customer? Probably not.
"How about an email address?" feels like I am demanding an email address. "Do you have an email?" would be more polite - even though you know the answer is almost certainly "yes" it is a more respectful way of asking.
I am an Indian, I learnt English as my second language. I feel that 'how about', 'what about', and even 'let's' can be used in informal conversation. "Shall we go to lunch?" is perfect. I am very happy that we need not say "Could we go to lunch?"
