Thanks, glad you like the site! Yes that is correct—all of the books I sell are in the public domain.

I use Sendgrid to send emails, which has worked great so far although it took a while to get my account fully set up.

Re: customers, so far I've had more than 10 and less than 1000. One encouraging sign is that many people are coming back after finishing their first book and buying another.

Very cool! Did you have any issues with Sendgrid mails ending up in spam?

[andrewedstrom]

I haven’t had any issues with that. However I don’t send any marketing emails, and since people are paying me to send them these emails I think the chance of getting flagged as spam is particularly low.
