Threads scheduler for newsletter writers
Built for the cadence newsletter writers actually post at — not generic marketing tools.
Start with Growly →If you're one of the newsletter writers reading this, you already know the trap: substack discovery is closed; you need a feeder channel. The hardest part isn't the writing — it's the cadence. Growly's slot + draft pool system was built to solve exactly that. Set the rhythm once, fill the pool when you're inspired, and the right issue cliffhangers ship at the right times without you babysitting the calendar.

A typical week with Growly
- Monday: open Growly, scan last week's per-post analytics — find the issue cliffhangers that hit hardest.
- Tuesday: draft 3-5 new issue cliffhangers in the composer, tagged by topic.
- Wednesday-Friday: slots fire automatically; you respond to replies in the Engagement tab.
- Sunday: 10-minute pool top-up so next week's slots have ammo.
Recommended cadence
For newsletter writers, the sweet spot is usually 3-5 posts per week with at least one thread on Fridays. Set two slots (Tuesday 9am + Friday 12pm), aim for 8-10 issue cliffhangers in the pool, top up weekly.
