In short

How do I check scheduled social posts for errors before they publish?

Every Monday, WebRun opens CoSchedule, reads every social message scheduled for the coming week, and checks each one: the link resolves, the image is attached, the profile is right, and the copy fits the network. It drafts the fix list in Gmail and posts the issues to Slack.

  • A dead link is caught before it publishes, not after
  • Every queued message is checked against the profile it posts to
  • A clean week is confirmed as clean, so silence is not ambiguous

Good to know

Questions, answered

Will it edit or publish any of my posts?

No. WebRun inspects the queue and reports problems. Editing copy, swapping an image, changing a profile, and publishing all stay with your social manager.

Does it send the fix list by email on its own?

No. The note is left in Gmail Drafts for you to read and send. The Slack post is an internal message to your own channel.

What counts as a problem?

A link that fails to resolve, a message with no image where your account normally uses one, a message pointed at the wrong profile, and copy longer than the network allows. You can add your own checks.

Put this on autopilot.
