I do graphic design work for a client who regularly asks me to design emails. She has me do the design and send it as a jpeg to her to approve and she then sends it to our web guy to send out in a mass email to our clients and put on our website.  She often asks me to add button designs for the web guy to make into clickable links.  Every other email she forgets that I’m just making the design and that our web guy adds the links on his end and we end up having this conversation:

Client: The button doesn’t work.

And then, before I can reply:

Client: Call the web guy and ask him how to make a clickable button.

Me: He makes the links clickable on his end.  This is just the design.  Even if I were to make the whole image a clickable hyperlink to you in this email it will not carry over when you send it to him and he will have to redo it when he sends it out via email and adds it to the website.

Client: WHY DO YOU HAVE SUCH A PROBLEM CALLING HIM WHEN YOU DON’T KNOW HOW TO DO SOMETHING?!

The web guy and I have an understanding that we may have to call each other with stupid questions we both know the answer to with her standing behind us listening from time to time.
