Suppose an investor on the Solo plan saves a dynamic list of absentee-owned, high-equity properties in two ZIP codes, and it returns 4,000 properties. Monitoring it fits inside both limits. Before the first drop, the investor copies the properties to a static list and exports it once, which uses 4,000 of Solo's 10,000 monthly exports.
That export starts going stale as owners sell and move, so it isn't the mailing file for drops two and three. Before each later drop the investor opens the static list, where each record shows the latest owner and mailing address in PropertyRadar's data, and compares it with the original export. A recent sale may not have reached PropertyRadar's record yet, so check the county for any property where the timing matters. A property whose owner has changed comes off the list. So does anyone who asked to stop receiving mail. Each removal goes in the campaign log with its reason. An owner who has only moved stays on the list with the new address.
Suppose 35 properties change owner and 12 owners ask to stop before the second drop, then 28 and 9 before the third. The three drops go to 4,000, 3,953 and 3,916 properties, which is 11,869 pieces in all. The log holds a dated reason for each of the 84 removals.
Export allowance is counted separately from mail pieces. The first export used 4,000 records once, and it can be downloaded again without using more. A fresh export of the static list before drops two and three would use 3,953 and 3,916 records in the months those exports are made.
The dynamic list keeps changing while the campaign runs. Set New Since to the export date to see the properties that joined afterward, and put them in a second static list that starts at piece one. The list a property sits on then identifies its starting group, and the mail house's dispatch record shows which pieces it was sent.
