The principle is simple but the impact was significant. Before: Gut health supplement brand preparing to launch a new product to their email list. Their previous launch emails had open rates between 10-14%. Subject lines were things like: ""Introducing our new probiotic formula"" ""New product alert. GutRestore Pro is here"" ""The supplement you've been waiting for"" Standard launch email subject lines. Brand-centric. Product-centric. After: We rewrote the subject lines using a simple principle. Open rates on the launch sequence went: Email 1: 38% open rate Email 2: 31% open rate Email 3: 42% open rate (the highest, I'll explain why below) The principle: Subject lines that reference the problem outperform subject lines that reference the product. The old subject lines were about the product: ""Introducing GutRestore Pro."" The reader thinks ""I don't know what GutRestore Pro is and I don't care."" The new subject lines were about the reader's problem. I pulled the specific language from customer reviews of their existing products. Without sharing the exact subject lines (the brand asked me to keep those private), I can share the structure: Email 1: Referenced a specific symptom their customers commonly describe (not the clinical term, the way real people describe it) Email 2: Referenced what the reader has probably tried before that didn't fully solve the problem Email 3: Referenced the specific moment that makes the reader realize the problem is affecting their daily life Email 3 had the highest open rate because it used the most specific, recognizable scenario. Same principle as ad hooks. Specificity beats generality every time. The subject lines never mentioned the product name. They never said ""new"" or ""launching"" or ""introducing."" They just described the reader's experience in a way that made them think ""that's me, I need to open this."" The product reveal happened inside the email, not in the subject line. By the time they got to the product, the email had already established that it understood their problem. This principle works for any product in any category where the customer has a problem they think about regularly. Lead with the problem. Earn the open. Then introduce the product.   submitted by   /u/JMALIK0702 [link]   [comments]
