AI is now a core part of email marketing automation. Look for features like:

• AI subject line optimization
• Predictive send times
• Email segmentation automation

These capabilities improve engagement and conversion rates.

Scalability

A scalable email marketing platform should grow with your business. Some tools offer shared IPs (lower cost), while others provide dedicated IPs (better deliverability for large senders).
