How to create better subject lines ✍️
Here’s some additional advice on how to craft better subject lines:
➡️ Use our subject line generator to generate subject lines based on the content of your email.
➡️ Write personalized subject lines that go beyond just including a first name. Instead, mention a pain point, competitor, or common ground between you and your prospect for superior open rates.
➡️ Ask a relevant question like: “Need help with {{painpoint}}? or “Happy with 50% open rates?”
➡️ Add urgency to your subject line. Example: “Here’s an invite to the event of the year, {{firstname}}).”
➡️ A/B test your subject lines. You’ll never know exactly how your subject lines will perform unless you extensively test them against each other.
