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.
