Which preposition is correct, please?

1) She contacted me by / through e-mail.
2) Jenny gets a sonnet of Shakespeare by / through e-mail every day.
3) Emma knows how to send an SMS by / through e-mail.

It seems like both are correct in all three cases. Am I right?

Yes; "contact me via/by email/e-mail" sounds most likely to me.

"Through e-mail" is sometimes heard in more general statements, with the sense "by means of e-mail":

1. "Through e-mail, I've kept in touch with many people I would never have written a letter to."

2. "Through e-mail, we can contact people immediately without having to speak to them."

In all cases you are probably best saying by.

She contacted me by e-mail.

You could say through but it is a little bit clumsy but OK nevertheless.

You would use through in "he sent a letter through the post" but "he sent a letter by post" would be OK also.

You could also say "She contacted me via e-mail".

Personally, I spell email "email".
Students: Are you brave enough to let our tutors analyse your pronunciation?
i usually say

via email
It depends on the context of the sentence.
Via would be the cunning word to replace by and through.
Sadeemi usually say

via email

"Via" literally is correct but not commonly used in the US. Poeple ususlly said "you may contact me by e-mail or by phone".

I've just read through Fowlers and Longman style guides. Via means "by way of", and it is usually only used when concerning routes: London to New York via Finland. Sometimes via is loosely used to mean "by means of"; however, you're usually better to use "through" or "by" when you are writing about a means of transport or a method of communication. I, personally, would recommend using the word "by". I would also, in general, be careful when using the word "through", because it can be ambiguous. The example given in the Longman style guide is "send a message through the milkman" [italics included in the original quote]; however to me, that sounds like cruel torture, because I have a literal image of someone pushing an envelope through the milkman's chest.

Please don't add posts that contain nothing but a quotation of the original question. It adds nothing to the discussion to ask the same thing again, especially when the answer has already been given.
