Send It! · with Jimmy Kim & Chase Dimond · March 18, 2025 · 33 min
Summary
This episode emphasizes the critical importance of maintaining clean email and SMS marketing lists for ecommerce brands. Dirty data leads to wasted ad spend, damaged sender reputation, and ultimately, lower conversion rates. Learn actionable strategies to audit, segment, and continually cleanse your customer data for maximum ROI.
Key takeaways
Implement a regular audit schedule (at least quarterly) to identify and remove inactive subscribers, bounced emails, and spoofed numbers. Don't wait for deliverability issues to arise.
Segment your audience based on engagement levels and purchasing behavior. Tailor content to highly engaged segments and re-engagement campaigns for less active ones, rather than blasting your entire list.
Utilize suppression lists effectively to prevent sending to known non-buyers, complainants, or those with consistently poor engagement. This protects your sender score and improves campaign efficiency.
Leverage zero-party and first-party data collection methods (e.g., preference centers, surveys) to gather accurate subscriber information directly, reducing reliance on third-party data and improving personalization.
Understand key metrics like open rates, click-through rates, and bounce rates as indicators of list health. Proactively address declining metrics to prevent long-term damage to your email deliverability.
