Did I send too many messages?

Nancy emailed me and said she would email Susan with information to send to me. I emailed Susan asking for the information that Nancy sent her and she said she’ll email it to me when she receives it. Meanwhile Nancy already told me she emailed it so I sent susan another email saying Nancy sent it over. I didn’t hear back from susan so I emailed her again. I said I want to make sure you received the information cause if not I’ll ask Nancy to send it again. Susan said here it is I received it 2 days ago. I thanked her and let her know that Nancy is sending over a little more information. She never responded. I don’t know if she’s just busy but I feel like I’m spamming her trying to get the information. There was a guy mark we were going to reach out to next week but I decided to send him an email and cc’ed her so she just saw me in her inbox again. I feel kind of awkward, impulsive, impatient, cause I don’t want her to think I’m acting that way. Is this emailing too much? I don’t usually email them this often. Weirdly I feel like this will affect our relationship in terms of partners even though we’ve been fine I just feel weird.
