Do everything – EVERYTHING – with a separate wedding-planning only email address.  It will be your login for registries, your wedding website, emails with vendors, RSVPs if you’re going paper-free, etc.  Bonus points if it’s an email address both you and your fiance can check, so he can stay fully in the loop and it won’t fall to you to forward contract drafts to him.  Learn from my mistakes, oh engaged people of the internet.  Learn from my mistakes.  I am still on the automatic listserve of the woman who used to run the rental business for water taxis.

PS – Water taxi was still totally worth it.
