Email remains one of the highest-ROI channels when permission is clear and messages are relevant. Automation scales personalization only when strategy leads tooling.
Permission and expectations
Use double opt-in where regulations require it; always explain what subscribers receive and how often. Make unsubscribe obvious. A smaller engaged list outperforms a bloated cold database.
Core automations
Welcome sequences should onboard users to your product or content promise in three to five tight emails. Abandoned-cart or browse flows work for ecommerce. Re-engagement campaigns should sunset inactive contacts to protect deliverability.
Segmentation
Segment by behavior—what they clicked, purchased, or downloaded—not only by demographics. Dynamic content blocks keep one master template useful across segments.
Measurement
Track deliverability, open rates (with iOS caveats), click-through, and attributed revenue. Optimize subject lines and preview text first; they drive the rest of the funnel.
