This is a simple and yet effective way of writing email subject lines. Simply telling or reminding your customer about their abandoned cart.

  • You forgot something
  • Did you forget something?

These subject lines include the first name of the customer to bring the conversation home. A personalized subject line can read like the following:

  • Hello Emma, You left your cart open
  • Hey Jane, thanks for visiting us
  • Hey Bailey, get a 10% discount when you check out.

Report from CampaignMonitor proves that emails with personalized subject lines get up to 26% open rate.

Offers and Discounts

Customers never get tired of taking advantage of discounts and you can’t get tired of offering them. Subject lines that start off the email telling customers of a beneficial reason to complete their purchase can be effective.

  • Get 20% off when you empty your cart
  • 30% off is waiting for you on all that is in your cart
  • Get free shipping on all that is in your cart.

Time-Bound Offers

Time-Bound offers create urgency about an offer and tell the customer to come back and checkout before they lose it.

  • 30% off when you check out this week

  • You forgot something comfortable in your cart
  • Get your skin glowing, don’t wait to check out.

Building Curiosity Subject Lines

There are subject lines that get most people to just click open a mail. Sometimes you would have to ditch all the cart related lines and go for something completely different.

  • Jane, we have something for you
  • A gift for you
  • We picked this out just for you

This gets the customer curious enough to open the email to see an offer tied to completing the action of checking out.

FOMO (Fear of Missing Out) Tactic

Creating scarcity of a product has been one of the oldest tricks in the book for getting customers to pay now. This rule also works very well with abandoned cart email marketing. You can use subject lines such as:

  • Your cart is expiring
  • Stock is running out.
  • Limited Offer
  • Your product is selling fast

Nudging Subject Lines

These subject lines intend to give the customer a simple push in the right direction. First assuring them that you understand why they might not have checked out, you are with them through making the decision and enjoying the product that they have looked at.

  • Don’t worry, we’ve got you
  • You are almost there
  • You can use your Juliana choo handbag

Customer Care

The customer is asked if they need help with anything or if they had issues while shopping. This comes with the assumption that the customer needed help along the process of checking out.

  • Do you have a problem with your wifi?
  • Did you have quality service?
  • We are here to help!

More Reasons to Buy

Giving customers more reason to buy is convincing them on why each and every product is in their cart in the first place. It outlines the benefits and perks of the products chosen. This is used amazingly well by the travel company above.
