Why email is still the best investment
Email has three structural advantages over social media: you own the channel (Meta doesn’t decide who sees your message), conversion is higher (you land in the inbox, not in a feed full of noise) and the message lasts (it stays in the inbox until the reader decides). That’s why ROI per active subscriber is usually 5–10× higher than ROI per social follower.
The question isn’t whether to invest in email, it’s how much. This calculator tells you in euros, not gut feelings. If your annual value per subscriber is below €1, your list isn’t profitable, and you need to fix conversion before adding subscribers.
How to increase email ROI
- • Clean out inactive subscribers: every 3–6 months, remove people who don’t open. It improves deliverability and lowers costs.
- • Segment: emails to relevant segments convert 3–5× better than mass sends.
- • Automate onboarding: a 5–7 email welcome series converts up to 10× better.
- • Improve your subject lines: the biggest lever on opens. A/B test every send.
- • One CTA per email: two CTAs cut total conversion by about 50%.
The number your newsletter should track
Don’t treat open rate as your final metric: Apple Mail Privacy Protection inflates it artificially. Look at CTR and, above all, revenue per send. If you take your newsletter from “€1,500 revenue per send” to “€3,000”, you’ve doubled its value without hiring anyone or spending more.
