When using the amplemarket searcher to do lead generation you'll find 2 categories of leads:
1) Leads in which we were not able to verify that the contact information is 100% valid but have a high probability guess.
2) Leads in which we were able to verify that the contact information is valid (email and phone number)
Here is what your choice of Data quality means:
- "Max Reach" option you'll include leads in 1)+2),
- "Max Quality" you'll include only leads in 1).
It's important to try to strike a balance between data quality and reach, since choosing "Max Quality" might reduce your total target audience.
