How do I retrieve a text message response sent to my email on iPhone?

Yesterday, I contacted someone I know. At first, I thought it was weird that they hadn't responded all day but I figured they'd get back to me. Today they asked me via text if I received their response only to be told that my text yesterday was sent to their email. They responded to that text email with the information I need but even a day later, it hasn't been sent to my iPhone or my text history with the person. Is there any way to get the response?

Yea have them send the response to your phone number instead of email address.
