Our RSVP date was June 1st. We started following up with people on June 2nd. The problem is, I still haven't heard back from 75 households. I have contacted everyone at least twice, and through different means of communication: If I e-mailed the first time, I called the second time, or vice versa. Some people I have even had FI contact, too. How many times is too many? I feel like a nuisance, but my deadline for some of my vendors is coming up in a couple days so I really need to know. How many times would you contact someone before just assuming they were a "no?"
