6. Using ChatGPT / Jasper for Email Copy

Tips for AI Email Marketing
- Always A/B test AI-generated subject lines against your historically best performers
- Use AI for structure and first drafts, then add personalization manually
- Don’t automate your entire voice — keep at least the personal sections human-written
- Monitor unsubscribe rates after switching to AI-generated sequences — it’s the best signal
Final Thoughts
For most small businesses and bloggers, the AI features within Mailchimp, ConvertKit, or AWeber are sufficient. E-commerce brands should look seriously at Klaviyo. Teams that need full automation sophistication should evaluate ActiveCampaign. And for pure email copywriting, pairing any platform with ChatGPT or Jasper is currently the most flexible approach.
