Common Email Marketing Mistakes

❌ Using No-Reply Email Address
People want to reply. Use real email address (hello@, support@, yourname@).

❌ Sending Without Testing
Always send test to yourself and check on mobile phone first.

❌ No Clear Call-to-Action
Every email needs one primary action. Make button obvious.

❌ Relying 100% on AI Content
AI writes good drafts, but add personal stories, specific examples, your personality.

❌ Ignoring Mobile
60%+ open emails on phones. If it doesn’t look good on mobile, redesign.

❌ Not Segmenting
Sending same email to everyone wastes opportunities. Segment by interests, behavior, purchase history.

❌ Irregular Sending
Set consistent schedule (weekly, monthly). Sporadic emails get forgotten/unsubscribed.

❌ No Welcome Sequence
First email gets highest engagement. Create 3-5 email welcome series.
