There are two methods to do this in Contact form7 and both are very easy:
In this method you can add multipple email addresses seprated by comma(,). You can see below image.
you can enter the primary email in the “To:” field, as well as add CC (carbon copy) or BCC (blind carbon copy) headers in the ‘additional headers’ section.
A quick reminder that if you use CC, all recipients will see who received the email, use BCC to hide a recipient.
