• Engagement Index in Simon Predict: We've introduced the Engagement Index, a brand-specific metric for measuring customer engagement. Use it to identify top prospects for campaigns, build lookalike audiences, or replace outdated engagement criteria. This flexible tool helps you tailor marketing strategies based on real engagement insights.
• 1:1 Couponing Assignment: You can now perform per-contact coupon or voucher assignment within Simon. This allows you to send contact-specific coupon codes that are assigned at the time of send. It's also compatible with Journeys branching, allowing you to send different lists of coupon codes to different groups of contacts in different variants of your campaign. Read more about it here.
• Custom Headers in Simon Mail: Simon Mail now supports custom headers (also known as x-headers)! These can be leveraged for a variety of use cases -- for example, managing your deliverability by integrating with ISP-specific deliverability insight tools. Check out some of our sample use cases and how to configure x-headers for your Simon Mail campaigns here.
