Frequently Asked Questions
Why does email still have the highest ROI?
Direct, owned, and durable. The reader explicitly invited you in. As paid acquisition costs rose and social organic reach declined, email’s relative ROI grew. $36–$42 per dollar spent has held steady for a decade.
What’s the most underused email play?
Behavioral segmentation (#241). Most brands send the same email to everyone. Splitting by behavior into 5–7 segments routinely 2–3x’s email revenue. Highest-ROI single change for any mature email program.
Should I use a generic ‘subscribe to my newsletter’ lead magnet?
No. Specific named lead magnets convert 5–10x better. “The 2026 SaaS Pricing Audit Checklist” beats “subscribe to my newsletter” by an order of magnitude on relevant pages.
How often should I send emails?
Test it. Some lists thrive on weekly; others optimal at twice-monthly; some segments tolerate 3x/week. Test frequency by segment; the optimum varies. Sporadic isn’t a strategy at any frequency.
Are open rates still meaningful?
Directional only. Apple Mail Privacy Protection inflates them. Reply rate, click rate, and forward rate are more reliable signals of real engagement.
How do I improve deliverability?
Authenticate (SPF/DKIM/DMARC), use a real reply-to address, clean unengaged subscribers regularly (180-day sunset is standard), avoid spammy patterns, make unsubscribing easy. Most deliverability issues come from list neglect.
