I think it might also depend on how soon your wedding is. She has been very responsive to me in the last few weeks - usually responding to emails within 2-3 days. My wedding is in 2 weeks though, so she seems to be more responsive now than she was a few months ago. If it's been longer than 2 weeks, you should maybe just try sending her a follow up/reminder email just in case the email fell off her radar. Ariana is still around - she emailed me yesterday, but it's been frustrating communicating over the last year!
