Deliverability and compliance
AI can hurt you if you’re careless. Generic, hyped phrasing (“Act now! Limited time!!!”) trips spam filters, so edit AI copy to sound human and specific. Always respect consent and privacy law, AI doesn’t excuse emailing people who didn’t opt in, and keep your list clean to protect sender reputation.
Mistakes to avoid
- Sending unedited AI copy. It’s generic and can sound spammy.
- Over-personalizing. Creepy beats relevant, use data tastefully.
- Ignoring deliverability. Watch spam words, formatting, and reputation.
- Skipping tests. Let data, not guesses, pick subject lines.
- Forgetting compliance. Consent and unsubscribe handling are non-negotiable.
