It had 3 experiments. ## Do friends open my mail more than strangers? I split the list into 2 groups: 1. My contacts: ~1,000 people I knew (I've mailed them) 2. Strangers: ~1,700 people I didn't know (I've never mailed them) **My guess**: strangers would open the mail 30% less often. **Reality**: They opened it 40% less. 50% of my contacts opened the mail, vs only 28% of strangers. ## Are the first and last links most clicked? I sent 2 versions of the email to my contacts. The order of links was different. - [Book reviews](/blog/books-in-2021/) did 30% worse at #6 than #1 (62% down to 43%) - [PyCon talk](https://youtu.be/vEvHq4qW3bk) did 67% worse at #4 than #1 (10.4% down to 3.4%) - [Landmark course](https://www.landmarkworldwide.com/advanced-programs/leadership-and-assisting-programs/introduction-leaders-program) did 7% worse at #4 than #2 (20.7% down to 19.2%) - [write more about](/blog/can-foreigners-enter-hollywood/) did 100% worse at #4 than #2 (4.4% down to 0%) - [Tools for Data Science](https://onlinedegree.iitm.ac.in/course_pages/BSCSE2002.html) did 39% better at #2 than #6 (17% down to 10%) - [Pranayama](https://www.artofliving.org/programs) did 62% better at #5 than #3 (3.4% up to 5.5%) **My guess**: the first and last links would be clicked 20% more often than those in the middle. **Reality**: The links higher up were clicked more often 5/6 times. Click rates drop but don't climb up at the end. ## Do provocative subject lines increase open rates? I sent 2 versions of the email to my contacts. The subject lines were different. 1. Bland: "My year in 2021" 2. Provocative: "Where I failed in 2021" **My guess**: the provocative title will have 2X the open rate of the bland one. **Reality**: The open rates were about the same (49% for provocative, 51% for bland). Either the second title was not provocative enough, or the bland was interesting enough. I need to re-run this experiment. ## Learnings I learned 3 things. 1. Strangers open my mails less than I thought. Make more friends 🙂 2. People scan emails top-down (not top-down, then bottom-up - like I do) and click on top links. Move the main link first. 3. I'm no good at creating high-contrast variations in content. Take help.
