Alan personally answers every email he receives. If you send a message and don’t get a reply, a spam filter snatched it up or you mistyped your address and his reply bounced.
Important: type your email address correctly. If you mistype it, Alan will get your message but you won’t get his (it bounces back to him as “undeliverable”). In fact, several of Alan’s recent replies have bounced, so if you don’t receive a reply, resend your email to: readers5 (at) alanjacobson (dot) com (but use the proper email format of firstname.lastname@example.org). Put the title of one of his novels in the subject line. He gets a lot of mail and this helps the message stand out. (The “name” field isn’t required, but it’s always nice to know who you’re replying to.)
