Our issue: we kick off x number of programs every morning that take several hours to send. In the meantime, we have prospects filling out web forms asking us to contact them to purchase our services.
The web form processing queues up until the sends are completed, meaning we don't know for several hours - sometimes not until the next business day - that those prospects tried to contact us.
This is no way to run a business. It happens to us on a near-daily basis. We're not a large company (~20MM/year in email sends). There is no way large Marketo customers are allowing this to happen to them.
What's the solution?
