AutoPilot allows you to monitor the quality of all email lists from your account at a specified interval of time: weekly, bi-weekly or monthly. Use this information to decide when to do the mailing list validation.
This step-by step tutorial will guide you through the purchase & activation process.
Please keep in mind that autopilot will monitor all the lists from your account (both uploaded & imported or via API).
After each Autopilot cycle is completed, you will receive an email with a report of your monitored lists. The report will help you assess when it is appropriate to do the mailing list validation.
