Definition
Common email marketing mistakes quietly drain results. Avoiding them is often easier and cheaper than fixing them later. The biggest offender is buying or renting lists, which breaks permission rules and destroys deliverability.
Other frequent errors include sending too often without monitoring fatigue, ignoring mobile where most opens happen, burying the call to action, skipping testing and neglecting compliance basics like a working unsubscribe link.
Discipline prevents most of these. Build an opted-in list, match frequency to engagement, design mobile-first with one clear CTA, test your emails, and always honor consent and opt-out rules. Small corrections here compound into better results.
