Client: “That’s way too much money to charge for an email campaign. It’s not hard to put a few graphics in an email.”

Client: “Can you talk for a second?”
Client: “OK. We made that email campaign, but I can’t figure out why all of the links take me to the unsubscribe page.”

Client: “Well…no. We already sent it.”
The client sent an email campaign to a list of 74,000 customers with every link in the email being a one-click unsubscribe.
