Even well-planned email campaigns can fall flat because of a few avoidable mistakes. Here are seven of the most common ones we see, and simple ways to fix each.
Email marketing is one of the most effective ways to stay connected with your customers, but small missteps can lower your open rates, send your messages to spam, or cause subscribers to tune out. The good news? Every one of these mistakes is easy to correct once you know what to look for.
Sending emails without permission
Adding people to your list because they gave you a business card, or worse, buying a list, is a fast way to get spam complaints and damage your sender reputation. It can also break email laws.
Weak or misleading subject lines
Your subject line decides whether an email gets opened. Vague lines like "Monthly Newsletter" get ignored, while clickbait that doesn't match the content erodes trust.
Ignoring mobile readers
A large share of emails are opened on phones. If your email has tiny text, wide images, or buttons that are hard to tap, mobile readers will close it in seconds.
Sending the same email to everyone
A brand-new subscriber and a loyal ten-year customer don't need the same message. One-size-fits-all emails feel generic and lead to lower engagement.
No clear call to action
If readers finish your email without knowing what to do next, you've missed an opportunity. Too many links or competing requests can be just as confusing as having none.
Emailing too often, or not often enough
Flooding inboxes leads to unsubscribes. Disappearing for months means subscribers forget who you are, so when you finally email, they may mark you as spam.
Not tracking results
Sending emails without checking how they perform means you're guessing. You'll never know which subject lines, offers, or send times work best.
Your pre-send checklist
- Everyone on this list opted in to hear from me.
- The subject line is clear, honest, and short.
- I previewed the email on a phone.
- The right segment is selected.
- There is one clear call to action.
- All links work and the unsubscribe link is included.
- I proofread for spelling and grammar.
Key takeaways
- Permission is the foundation of every successful email list.
- Clear subject lines and mobile-friendly design drive more opens and clicks.
- Segmentation and one strong call to action make emails more effective.
- Consistency and tracking help you improve with every send.
