Whether you run a product-based or service-based business, promotional email subject lines can be some of the trickiest to write. With high-tech spam filters, separate promotional email inboxes, and mandatory email marketing laws to follow, just getting in front of your audience can seem like breaking through Fort Knox. Effective email marketing for small business owners starts with sales email subject lines that work.

Thirty-five percent of people open emails based on the subject line alone, so your email subject lines for sales should be compelling enough to make prospects click.

But, what does it take to create those subject lines, and how do you know what subject lines will entice your audience to click open? Lucky for you, we’re sharing 70+ of the best email subject lines for sales and promotions.

What makes a sales email subject line effective?

Effective email subject lines for sales are the ones that people open. If no one opens your emails, they’re not effective. Make your email subject lines enticing by offering a discount, limited-time promotion, or sale on select services.

The three fundamental questions you have to ask yourself before sending off your perfectly packaged promotional email are these:

  • Does it offer an incentive?
  • Does it create urgency?
  • Is it short?

Trying to pack a punch in just a few words may sound tough, but in a fast-paced and mobile-driven society, these criteria are essential to have in your sales email subject lines. It’s important to get your audience’s attention fast, then follow through with content that delivers on what your subject line has promised.
