I get always confused with the possibility to use
verb + ed for the future. The text I'm writing brings the same problem and I'm not sure if I do a mistake if I write:
"Once we receive and review it, we will confirm your order by e-mail."
"Once we received and reviewed it, we will confirm your order by e-mail."
Which one is correct - can anyone please explain me the rule of how to use
verb+ed in this case?
