Using jq with bash to run command for each object in array

How can I run a Bash command for every JSON object in a JSON array using jq? So far I have this:

cat credentials.json | jq -r '.[] | .user, .date, .email' | mycommand -u {user} -d {date} -e {email}

This doesn't seem to work. How can I take the parameters out of the JSON array into my command?

My JSON file looks something like this:

["user": "danielrvt","date": "11/10/1988","email": "myemail@domain.com",   ...]
