How to transfer cold contacts to opt-in marketing systems?

Transferring cold contacts to marketing systems requires a clear consent moment, not automatic migration.

Proper transfer process:

• Ask for explicit marketing consent during or after sales conversation
• Use subscription forms for formal opt-in
• Document when and how consent was given
• Explain what they'll receive and how often

Consent request approaches:

• End of sales call: Would you like to receive our newsletter?
• Follow-up email: We share monthly insights. Want to subscribe?
• Customer onboarding: Check box for marketing communications
• Preference center: Let them choose what to receive

What not to do:

• Automatically add anyone who replied to cold email
• Subscribe based on meeting attendance
• Assume business relationship equals marketing consent
• Pre-check marketing boxes in forms

Data handling:

• Mark consent source in CRM (distinguishes from cold data)
• Track consent date for documentation
• Sync suppression lists between systems
• Respect unsubscribe across all systems

The cargo may have arrived at port, but customs still requires proper documentation.
