It’s crazy to think that once September comes along, businesses only have a few short months to finish out their year strong.

A great way to achieve this is by running an email marketing campaign! However, September is a busy time of year not only for consumers but for small businesses as well. Unfortunately, some businesses even tend to shy away from emails during this time due to a lack of resources to come up with consistent copy.

Don’t let this hold you back from reaping the benefits of a September email campaign! We brainstormed September email subject lines to help guide you to killer September emails that will bring in results that will last through the end of the year. Plus, we’re answering questions like:

  • Why should I run an email marketing campaign in September?
  • What are some subject line best practices to consider?
  • What should I put as the subject in my September emails?

Why run email marketing campaigns in September?

Email marketing is a perfect marketing strategy to run year-round. September, though, is an especially great time to capitalize on email marketing because consumers aren’t yet busy with winter distractions like the holidays.

Here are some ideas for your September email marketing campaigns:

  • Promote a Labor Day sale or promotion
  • Let customers know about your back to school events
  • Educate customers about how to weatherize their house for winter
  • Share updates to fall or winter hours
  • Tell customers about your new loyalty program

While you don’t need a specific reason to send email marketing campaigns, having a goal in mind for your email can help you craft the best subject line.

Why is a good email subject line so important?

So, you know you want to include email as part of your September local marketing strategy. However, a strong email subject to ensure your success this month is just as important as the email content itself. These email marketing trends explain why:

  • 64% of consumers decide to open emails based on subject lines alone.
  • Nearly 70% of email recipients report emails as spam after simply reading the subject line.
  • Businesses only get about 30 characters to make a visible mobile subject line, and 82% of businesses keep their subject lines under 60 characters.

These numbers prove that this September, you’ll need to pack a punch within a small amount of space to increase your email open rates.


4 email subject line tips to keep in mind

To provide some background on how we came up with the September email subject lines we’ll walk through today, here are four email subject line tips:

1. Be concise

Since your email subject line is your recipient’s “first impression” of what they’re about to open, you don’t want your email to get cut off in the preview. Check out this full list below of max characters you’d need to cut down to in order to have your full subject line show in the inbox preview screen.

2. Try to personalize your subject line

If at all possible, try to include the first name or another personalized feature within your subject lines this September to enhance your results. Emails that include your recipient’s first name in the subject line have a higher click-through rate than those that don’t.

A personalized marketing experience is always a good idea, but this September it will be vital to your email’s success. If you don’t have all the resources to plug in tons of names into your individual email subject lines, leverage a marketing partner that has the technology to do so for you!

3. Give emojis a go

While this might feel counterintuitive when creating a professional email, it’s been proven that 56% of brands using an emoji in their email subject lines had a higher open rate. September is the perfect time to try this since there’s plenty of fun fall emojis you can relate back to the purpose of your email—whether it be a pumpkin next to your fall event announcement or leaves swooping in on your back to school sale promotion.

4. Offer value

We know that viewers are going to scan through our subject lines and decide to open on a whim. So you’ll want to always be answering the “So what?” behind why your recipient should open your email. For example, if you’re running a giveaway or contest, emails including the word “free” in the subject line are 10% more likely to be opened.
