Fear of Missing Out(FOMO)

When limited things are available or the offer ends soon then it gives more quick sales than a normal scenario. Scarcity can be a powerful driver of sales, particularly when limited quantities or time-sensitive offers are involved. As such, leveraging scarcity can be an effective means of generating urgency and motivating customers to make a purchase.

Example of FOMO subject lines

  • This is the last call, we won’t disturb you again
  • Offer ends tonight
  • The first 50 lucky users get a discount
  • Only 5 seats are available
  • Live webinar, No recording is available
  • Last chance to grab the deal

Funny Subject Lines

Using funny subject lines can make people feel happy and relaxed. When a subject line is humorous, it can make the reader smile and want to open the email. For example, food delivery or vegetable sellers could use funny subject lines like “What if we delivered your veggies by drone?🚀” or “Feeling guilty about not eating your veggies? We’ve got you covered!😉”. By using humour in their emails, businesses can create a fun and positive connection with their customers.

Few Examples of Funny Subject Lines

  • What if we delivered your veggies by drone?🚀
  • What did you say? this is so cheap, you want to pay more😱
  • We’re dropping a bomb receipe😁 – source swiggy

Money-Saving Schemes or Offers

Everybody loves a good deal! When we see something we want at a lower price than usual, we’re more likely to buy it. That’s why many brands offer discounts and special deals on special occasions. By offering these deals, businesses can attract more customers and make more sales than they would otherwise.

Example of Money Saving or Offers Subject Lines

  • Use code [xyz] to get the best discounts

Understand Them

Have you ever had a friend who just “gets” you without even having to say anything? It feels really special, right? Well, the same goes for businesses. When a business understands what its customers are going through and provides solutions that address those needs, it creates a special bond between them. People appreciate when a business “gets” them and are more likely to read their content and engage with their brand.

Subject Lines Examples

  • Get rid of your uninvited pimples.
  • Score in your exam with these tips.
  • Getting bored with the regular breakfast? here is an interesting breakfast list.

Reminder Subject Lines

People are often busy with their work and might forget to complete certain tasks, even if they are important. For instance, they may have intended to buy a subscription or product, but then got sidetracked by a phone call or email. As a solution, businesses can send reminder emails to help their customers remember the task they had intended to complete.

Examples of Reminder Subject Lines

  • It will take 2 min to process your transaction.
  • Your cart item’s price has been dropped, check now.
  • [Name], You may also like a product similar to your interest.
  • A product similar to your interest is available at a cheap price.

Clear & Direct Subject Lines

It’s often more efficient to be direct and clear, rather than trying to be fancy or creative. Sometimes simplicity can be more attractive than complexity. Here are some examples to illustrate this point.
