The subject of your email is the most important sentence in the entire email campaign's content. The Invesp study in 2021 says that over 69% of email recipients report that your subject line is to get the receiver to open the email. The subject should intrigue them so they'll want to read more. The subject line needs to be written to entice the person to open the email.

One way to do this is by writing an obvious headline or describing something they are interested in. I'm confident that email personalization can be a powerful advantage if done correctly. If you use the full benefits of personalizing emails, it should be advantageous. SmartWriter has created several innovative ways to personalize and create new customer experiences for your company's email strategy.

Our advanced email features enable you to create new, exciting experiences that will increase your company's email response. This can be achieved using the Smartwriter Converting Subject Lines feature, where your business can create a hyper-personalized subject line. 

Final Thoughts 

Knowing how to write a great email opener can mean the difference between a sales opportunity and a missed opportunity, especially when you're reaching out to strangers. Some people don't take kindly to being cold-called, which is why it's important to develop as many email openers as possible. Not only will having multiple different opening lines at your disposal give you flexibility for sending exclusive discounts or free content, but it will also ensure that each message you send is received in the best light possible.
