When you trigger a mailing from the Lead Scout platform, here's what happens:
The mailing then gets added to the Lead Scout printer network queue. The queue and printing process takes anywhere from 1-3 days.
The mailing is then sent to USPS for processing and delivery, which can take anywhere from 2-5 days.
The expected turnaround time from when you hit "send" to mailbox delivery is typically 7-10 days.
