Q: Please send email on your purchase invoice .. I do not know from this work and I hope to respond and thank you

Not entirely sure what you are asking (and we are fellow users on these forums, we can't send you anything). You will automatically get an emailed receipt for your iTunes store purchases, though mine sometimes don't arrive until the following day. Or to your account's purchase history : See your purchase history in the iTunes Store on a Mac or PC - Apple Support
