You can fine-tune your data flow to your email sequencer in several ways: 1. Add custom variables to your API call for more granular control over your sequence.
2. Create separate fields for different steps of your sequence, including:
• Email body one
• Subject line one
• Email body two
• Subject line two
• And so on...This approach enables you to create highly personalized, multi-step sequences for each lead while maintaining efficient control over your outreach campaigns.
