Automated Failed Delivery Follow-Up Emails
Every few minutes, WebRun checks Onfleet for newly failed deliveries, drafts a friendly rescheduling offer for each recipient, saves it in Gmail for team review, and posts a Slack alert so a dispatcher can approve and send before the customer loses confidence.
How do I automatically follow up with customers after a failed delivery?
WebRun monitors Onfleet every few minutes for failed deliveries, drafts a personalised rescheduling offer for each recipient in Gmail, and sends a Slack alert so a dispatcher can review and approve before anything reaches the customer. Failed deliveries are recovered faster with no manual drafting required.
- Every failed delivery gets a rescheduling offer drafted within minutes, not hours
- Dispatchers review and approve before any message reaches the customer
- Repeat failures are flagged separately to prevent duplicate outreach

Questions, answered
Will it email the customer automatically when a delivery fails?
No. Every rescheduling message is saved as a Gmail draft for a team member to review and approve before it reaches the customer. Nothing is sent automatically.
What information does the rescheduling email include?
It includes the recipient's name, the original delivery window, the failure reason captured in Onfleet, and a clear offer to rebook. You can provide a tone or template for WebRun to follow.
What if the same delivery fails more than once?
WebRun deduplicates by task ID, so a second failure only triggers a new draft if the task status changed again since the last run. Repeat drafts are flagged to dispatchers.
