Thanks for sharing. It's an interesting idea, to try to trampoline it into another related commercial project. I just checked my RTD analytics, I get around 1k pageviews to `/` per month. Unfortunately I don't have a related commercial product either.
When I started with Nodemailer, my goal was to build a cool product—not to become an unpaid helpdesk employee for life. But here we are. So, I’ve been trying to monetize the project in various ways for the past ten years. I’ve tried everything (license restrictions, freelancing and consulting, paid extensions, etc.), and each approach failed for different reasons. The only strategy that actually took off was using Nodemailer’s documentation page as a referral source for another relevant paid project.
