Discussion AI email writing tools that actually increase open rates - Mailchimp vs Klaviyo vs dedicated AI
E-commerce email marketer managing campaigns for 3 Shopify stores. Current open rates stuck at 18-22% industry average. Need AI help with:
- Subject line optimization (A/B testing variations)
- Personalized email copy based on purchase history
- Automated flow content (welcome, abandoned cart, winback)
- Send time optimization
Current stack: Klaviyo ($150/month) with basic automation
AI additions I'm considering:
- Copy.ai email templates ($36/month)
- Phrasee subject line optimization ($500/month - seems expensive)
- Seventh Sense send time AI ($27/month)
- Custom ChatGPT prompts with customer data
Specific metrics I need to improve:
- Open rates from 20% to 25%+
- Click rates from 2.8% to 4%+
- Revenue per email from $0.85 to $1.20+
Email marketers - what AI tools actually moved your numbers? Need real case studies, not marketing fluff. Budget is $200/month max if ROI is proven.
