I want to thank you for how much ImportOmatic 3 improved over 2.
A few months ago, I imported a big batch of records (we have a sales database, separate from our constituent database).
After a successful import of, nearly, 15000 records, we had, nearly, 5000 possible duplicates.
The problem was that many wives order, but our constituent database has the husband as the constituent.
In our non-production database, I removed all those records and re-ran the import.
Now that non-constituent spouses, phone numbers, and e-mail addresses are matched, my possible duplicate number went down to around 300.
That is hugely helpful.
