What if your favorite store was offering 25% off TODAY ONLY? Or maybe they're running a flash sale starting right now that you CANNOT miss?

You’d want to go check out the sale ASAP, right? That’s the exact feeling your Cyber Monday email subject lines need to incite.

If you don’t grab your customers’ attention right off the bat with an eye-catching subject line on Cyber Monday, they aren’t going to open your emails.

As a matter of fact, 64% of people report opening an email based on the subject line. That’s a lot of attention to lose if yours is boring.

And on the biggest day of the year for online sales, we’re talking $10.7 billion spent in 2021, you can’t risk an email marketing flop. 

Cyber Monday email subject lines that grab your subscribers' attention bring more visitors to your site and generate more sales on one of the most important days of the year.

Subject lines for email before Cyber Monday

Prepare your audience for Cyber Monday sales by sending preview emails a couple of weeks before the sale. Your customers start researching and planning early for the items they want to get. If you send the word out early, you'll be on their mind when it's time to shop because they'll remember the previous emails and early bird incentives you sent. Use subject lines that advertise your sales or promote an early discount code.

This is also a great time to show your most loyal customers some appreciation. Create hype among your VIPs with early access to Cyber Monday sales and deals that only they can get.
