This past week, we sent out emails with lead.first personalization. However, a client sent back an email asking that her name Lucy be used, not Laurie. The data on marketo says here name should be Lucy. The email address is attached to Lucy. Not sure how the personalization ended up with Laurie's name.
Have you validated that it was indeed Laurie and not Lucy? Is Laurie a Default value? Are there Duplicates? First name was changed after the send? Email was forwarded from a Laurie to a Lucy? When you follow the activity log, do you see anything that would help you out with this?
Ok. I misunderstood the question from the client. It appears the database was wrong. The clients name is LUCY but was listed in the database as LAURIE. The email address was attached to LAURIE. Problem solved
