I agree that they'd be better served to focus somewhere else, IMO
, unless maybe you can target certain zip codes that weren't flooded. (I haven't followed it closely enough to know whether or not that possibility even exists in that area.)
There will be people looking to switch plans even under these circumstances because they are unhappy with their current plan. Those kinds of motivated people will tend to show up at seminars if they are able to do so and will also tend to call the carriers when they see their ads.
While it wasn't the same level of devastation as Houston, we had a "500 year" flood event here one year around the time we did a mail drop. With the ones that do actually call you, (whether from the mail drop or something else) you are liable to go round and round trying to set up the appointment as they may be displaced from their home. This week turns into next week, and next week turns into "I'll just keep what I have, I'm doing ok with it." Others won't in a good frame of mind to be able to make a decision in the midst of dealing with contractors, etc. But some actually welcome the opportunity to talk about something else besides rebuilding.
I wouldn't be surprised if they don't get the usual pile of mail from the carriers.
