Newsletter — frequently asked questions

How often does the newsletter go out?

Roughly weekly — one email when something new ships. There is no drip sequence and no scheduled filler: quiet weeks mean no email.

What actually lands in my inbox?

New interactive system-design builds, handbooks, runnable labs and coding challenges, plus the occasional note on what changed across the site. Links to free pages, never a pitch.

Is any of it paid?

No. Everything on Vibe Engines is free with no account required, and the newsletter is the same — there is nothing to buy, so nothing to sell you.

Can I follow without giving you an email?

Yes. The site publishes a full RSS feed at /feed.xml, plus per-topic feeds, and every video goes to the YouTube channel. The newsletter is a convenience, not a gate.
