For the record, it took DataFast 3 months to reach $1K MRR (now at $30K MRR). So MailCheap is 9x faster!

Stolen playbooks

levelsio spent a day typing "do a full security audit" into Claude Code

levelsio says he ran a full security audit through Claude Code on every VPS and site he owns, on top of unattended Ubuntu upgrades with auto reboot. Each VPS is isolated on Tailscale with policies Claude Code generated, so a compromised box cannot reach his other servers, his MacBook or his phone.
