The story
A subscription box brand sending generic 'Your order is confirmed' emails via SendGrid had an 18% open rate. After connecting their SMTP provider to ExecCortex and enabling AI-personalized copy (referencing the specific items in the box and timed upsells), open rate rose to 54% and click-through to 22%. Monthly subscription upgrade revenue grew $8K.
"ExecCortex paid for itself in the first week. The team finally stopped chasing dashboards and started chasing growth."
