Most email problems come down to a handful of fixable mistakes. Here they are. 💖

Mistakes to avoid

Emailing too rarely — they forget you
Only ever selling — give value too
Weak subject lines — no opens
No clear CTA — no action
Ignoring list health — clean it regularly

💡 Value keeps you welcome. The fastest way to kill a list is only emailing when you want something. Mix genuine value with your offers, and people stay subscribed, keep opening, and actually buy when you do sell.

Frequently asked questions

What are the most common email marketing mistakes?

Emailing too rarely, only ever selling, weak subject lines, no clear call to action, ignoring mobile, and never cleaning your list. Each quietly costs you opens, clicks and sales.

Why is my email marketing not working?

Common culprits: you email too infrequently, only send sales pitches, use weak subject lines, or don’t make the action clear. Email consistently, mix value with offers, and focus each email on one CTA.

How often should I email my list?

Consistently enough that people remember you — for many small businesses that’s weekly or fortnightly. Regularity matters more than frequency; pick a rhythm you can sustain and provide value each time.
