Questions, answered

Will it contact customers without my approval?

No. Every reminder email is drafted and left unsent in Gmail. Your office manager reviews and sends each one before any message reaches a customer.

What if the customer already booked directly or called in?

WebRun checks Housecall Pro for any existing future appointment at the same address before adding a customer to the outreach list. Customers with a booking already in the system are skipped.

Can I use this for other recurring services like water heater flushes or fixture checks?

Yes. You can configure WebRun to look for any job type and any recall interval, not just annual drain cleaning. Set the job type and the months-since-last-service window in WebRun settings.

Put this on autopilot.
