Leads purchased from a third party provider are not automatically imported into the AMS. Leads cannot be signed up for automated emails without first obtaining their permission. There must be a record of that lead granting you permission to contact them via automated email.
If you choose to purchase leads, you must contact these leads directly via phone or personal email and request they visit your AMS landing pages to get more information. When they visit your AMS landing page, they can opt into your email marketing campaign. Your AMS will include them in future email campaigns only after they have completed this step. They must opt-in to participate in your future email campaigns. Please be aware that they may opt out at any time.
