One of our wedding guests is staying with relatives while waiting to find a new apartment, and therefore he is temporarily without a mailing address. He won't be moving until after the wedding. We would mail his invitation to him at their home but he says they are unreliable and has asked us to email it to him so he will be sure to get it.
I know this is bad etiquette, but we were wondering if we could do this: scan it so he'll get it in color and send it by email, then give him his real invitation when we can, so he'll have it as a keepsake.
