Asking inactive subscribers why they stopped engaging should be done in a polite and simple way. A short, friendly message works best, something like "We noticed you haven't opened our emails lately. Are our updates still useful to you?" You can also give them options to click, such as "I get too many emails" or "Content not relevant." This makes it easy for them to respond without much effort. Keeping the tone respectful helps avoid sounding pushy. It also gives you a chance to improve your emails based on real feedback. What other creative ways do you think could get honest responses from inactive readers?
