Postal Mailing Results as of June 30

As of June 30, nearly 38 letters have been returned undeliverable due to address issues. This was expected and more will likely be returned. About 35 people have taken the survey. Most people are answering the optional question (all questions are optional!) about their airport identifier. This helps with the follow-up queries asking to take the survey.

Today 214 people received a follow-up email. These 214 people were those who have not yet responded to the survey and no undeliverable mail was returned. I.e., those people who should have received the mailing.
