Tips to write unskippable email subject lines for sales
Your customers may get dozens of promotional emails every day. The best email subject lines seemingly jump off the screen in those crowded inboxes and instantly entice people to see what’s inside.
Use these tips to create those unskippable email subject lines to get clicks and boost revenue:
- Deliver one clear message: The subject line should accurately reflect the entire email, without bait-and-switch tactics.
- Keep it short and simple: A good subject line is around 30 characters long and can be understood almost instantly.
- Be obvious: Tell your email recipient exactly what to do (review us, download this, register here).
- Avoid suspicious-looking subject lines: All caps and words like “GUARANTEED” will turn people away.
- Avoid SPAM filter triggers: Using those suspicious words, clickbaity tactics, and obvious trickery will relegate your emails to spam purgatory and possibly damage your sender reputation.

- Personalize your emails: You have a better chance of someone opening your email marketing if they see their name in the subject line.

Subject lines for invitation emails
Everyone likes to be invited to events, but the best way to get a good response is by sending an email with an inviting subject line. For invitation emails, especially, make sure your subject lines catch the attention of your readers so they open the email.

Event reminder email subject lines
If you’re hosting an event, it’s essential to send reminder emails to invitees and registrants. Reminder emails serve to nudge people who haven’t responded to your invite and remind attendees of the upcoming event. These email subject lines should be catchy and inspire action without being overbearing.
Here are some gentle yet effective reminder email subject lines for your upcoming shindigs:
- Reminder: Mingle for a Mission

Example subject lines to ask for reviews
Asking for reviews is not everyone’s favorite thing to do, but reviews are essential for your business’s reputation and SEO. While it’s okay to solicit feedback from customers, it’s not kosher to offer monetary incentives for reviews. Make sure that when you ask for reviews, you do so from a feedback perspective and not in exchange for money or even discounts.
Here are some subject lines to help get those 5-star reviews:
- Satisfied with Smile Dental? Review us on Yelp!
- How was your service at ZenSpa?
- Thanks for visiting! Here’s a link to submit your review
