Are e-mails good evidence for bona fide marriage in I-130 petition?

Question

My husband is a US citizen living in USA and I'm in China, and the major communication between us is by e-mail. Although we have airplane tickets, family photos, Christmas cards and skype log to prove our ongoing relationship before and after getting married, should we print our e-mails and submit them as evidence of bona fide marriage too? There are more than 2000 e-mails between us during the past 2 years, and most e-mails are lengthy. Will the e-mails help the CIS officials to understand the nature of our marriage better? Or will it make CIS bored and confused to read our e-mails?
If e-mails are good for I-130 petition, how many e-mails should we print and submit? Or shall we print and submit the list of e-mail titles?
I'm frustrated with the paperwork for immigration and I'll appreciate the help from you.

Answer 1

in the end, if that's what you have, submit that. if you have other things as you say, you should submit those as well. there's no way to say if that will be sufficient. in the end, that's up to the interviewing officer to decide. nor is there any way to say how many emails would be considered sufficient. The interviewing officer will be much more interested in your testimony in any case. The emails and other things will only be signicant if your testimony is considered weak for some reason.

Answer 2

It is not an official evidence but it can be used. E-mails have become the norm over the usual pen and paper so I don't think it is a problem using it. Just make sure you put them in chronological order by dates.

Answer 3

I think email correspondence can be used to prove you guys married in good faith. Print as many as you. This is a credible proof of a bonafide marriage.
