  • Promoting an event? Use the word “invitation” or “event”
  • Monthly newsletter? Mention monthly specials and events
  • New products or services?  Use “new” or “now offering” in the subject line

Personalize your email subject lines

Make your readers feel like you’re writing to them personally. Make your sales email subject lines more friendly than sales-y. One way to personalize emails is to segment your email list into smaller ones based on type (customer vs. non-customers), activity (loyal customer or occasional), or participation or interest in services. Segmenting email lists for an email blast or newsletter enables you to send more customized messages to certain groups of people in your email list.

Keep it short

Research has shown that email subject lines that are less than 50 characters have the highest open rates. Too short and the reader won’t know enough to open the email and too long can overwhelm the reader. Aim to create subject lines that are as close to 50 characters as possible.

Use humor when appropriate

Using puns and humor that your audience will appreciate is another way to increase your email open rates. Appropriate humor can contribute quite a bit to solidifying your brand identity and help increase your business’s name recognition in your target market.

Add urgency

Let’s face it, everyone procrastinates and gets things done at the last minute. Creating a sense of urgency in your subject line is a surefire way to entice someone to take action. Whether you’re having an open house, sale, or special event let your readers know that the offer is for a limited time only. This includes follow up emails for last ditch efforts like day-of event RSVPs.

Write the subject line last

By writing the subject line last, you’ll ensure that the first thing the recipient sees is an accurate representation of what’s written in the email inside.
