I was spending hours sending cold emails by hand. Make.com sends one email every 15 minutes. Airtable tracks every lead. Brevo handles delivery and tracks opens and clicks. Runs in the background while you work. 1,000+ leads contacted. 71% open rate. First paying customers came through while I was doing something else. The exact blueprint for €37. Free tools only. No monthly costs. One day to set up. What agencies charge €500+ to build is here for €37.
