  1. Warby Parker: "Uh-oh, your prescription is expiring" - (an example of “Fear of missing out”) Reminding your readers of something they may have forgotten is valuable and doesn't sound spammy at all. Letting your customers know of some due payments or schedule check-up, a friendly & timely reminder will help them to add your services to their to-do list.
  2. Groupon: "Best of Groupon: The Deals That Make Us Proud (Unlike Our Nephew, Steve)" - (an example of being humorous) - Being humorous requires a bit more thought and creativity, but it can really pay off in terms of your open rates. That's what Groupon did with this subject line.

  9. JetBlue: "You're missing out on points." - (another example of 'Fear of missing out') - Developing curiosity is a problem that's core to intelligence & we humans are eager to know or learn more about something.
