Probably you’re seeing a massive amount of new memberships, renewals, and donations coming in at the NRA, or at least I hope so. Please do not harass the new members with relentless marketing requests and asking for more donations, it drives them away. It drove me away in the 1990s for several years, and others have noted the same problem and also left the NRA because of it.
I joined again several years ago, and again quickly became frustrated with the endless requests for donation, both email and snail mail, and the waste-of-money junk mail from you. The solution: I called in and got myself removed from those lists. It’s been very nice ever since. I get the American Rifleman each month (last time I chose digital), and a renewal notice once a year, and that’s it. Perfect.
Of course those endless requests for money must pay off and it is of course for a most worth cause, but alienating a lot of would-be members isn’t smart. So I suggest you make it a lot easier to opt out of that massive email/mail harassment. Or tone it down from the start. Either way, that’s my advice to the NRA.
