Automated Substack Publishing Gap Check
Every Monday, WebRun opens Substack, reads the scheduled posts and drafts for the next two weeks, works out which publishing slots have nothing ready, logs the gaps in Airtable, and sends you a short WhatsApp summary.
How do I check whether my next newsletter slot has a post ready?
Every Monday WebRun opens Substack, reads your scheduled posts and drafts, and works out which publishing slots in the next two weeks have nothing ready. It logs those gaps in Airtable with the closest-to-ready draft for each, then sends you a short WhatsApp summary so your publishing rhythm holds.
- Empty publishing slots are spotted two weeks out, not the night before
- Every gap arrives paired with the draft closest to ready
- The schedule table shows whether your backlog is growing or shrinking

Questions, answered
Will it publish or schedule posts for me?
No. WebRun only reads your Substack drafts and scheduled posts. Publishing and scheduling stay with you, so nothing reaches subscribers without your click.
How does it know which slots are mine?
You tell it your publishing days once, for example Tuesday and Friday. It checks the next two weeks of those days against what is actually scheduled in Substack.
What if a post is already scheduled?
That slot is marked filled and left alone. WebRun reads the live schedule each Monday, so anything you queued during the week counts.
