NavLead has a daily export limit of 2500 leads per 24 hours per Sales Navigator account.

This limit is to protect your account from potential bans. If you need to increase your daily export capacity, consider adding more Sales Navigator accounts. For example:

1 Sales Navigator account = 2500 leads per day

2 Sales Navigator accounts = 5000 leads per day

3 Sales Navigator accounts = 7500 leads per day

This way, you can scale your lead exports according to your needs.
