Links in a email to be built?


Hello All I have been asked to design an email form an existing template. Fine and all good but...

In the email the project manager has included links to the things like twitter logo, facebook icon etc... I have built it in AI and ignored all the links I would normally do (thinking they are for the build). But the traffic manager is saying can I put these in in illustrator?

I have hyper linked PDFs before but surely this is something that is done on the build end not the design end for and email? I have done quiet a lot of things like this but no one has ever asked me to put in links before surely this is and HTML stage thing? Confused! :)

Thanks All :)
