Hi – I am experiencing the same problem as DrumTone77, although I receive 5 emails not 6.
To answer your questions:
– I dont use a separate thank you page
– I receive 5 emails advising of the new submission, and also 5 emails to the senders email address.
– here is a link to my site : https://ctswindsor.com.au/contact-us/
– in the inbox I get all 5 emails coming in.
Thanks for your help!
Glenn
