The Three Key Elements of
Irresistible Email Subject Lines
Email is back.
Despite repeated proclamations of its extinction, rumors of the death of email marketing have been greatly exaggerated — especially since email and social media are a powerful combination. You might not reach the average college freshman, but for slightly older types (you know, the ones with the money), email is still the way to go in many lucrative mainstream niches.
You must first, of course, get your emails read. And it all starts with the subject line.
Email subject lines are a form of headline. They perform the same function as a headline by attracting attention and getting your email content a chance to be read.
So, headline fundamentals still apply. But the context is different, with the email space having its own funky little quirks that need to be accounted for.
Here’s the good news — email also implies a special relationship with the reader; a relationship that will get more of your messages read, even with subject lines that wouldn’t work in other headline contexts. Let’s take a look back at headline fundamentals, the specifics that apply to subject lines, and the “secret sauce” that makes email your top conversion channel.
1. The Fundamentals:When you’re writing your next subject line, run it through this checklist, based on the Four “U” Approach to headline writing:
- Useful: Is the promised message valuable to the reader?
- Ultra-specific: Does the reader know what’s being promised?
- Unique: Is the promised message compelling and remarkable?
- Urgent: Does the reader feel the need to read now?
2. The Specifics:Beyond headline fundamentals, these are the things to specifically focus on with email subject lines:
- Identify yourself: Over time, the most compelling thing about an email message should be that it’s from you. Even before then, your recipient needs to know at a glance that you’re a trusted source. Either make it crystal clear by smart use of your “From” field, or start every subject line with the same identifier.
- Useful and specific first: Of the four “U” fundamentals, focus on useful and ultra-specific, even if you have to ignore unique and urgent. There are plenty of others who work at unique and urgent with every subject line — we call them spammers. Don’t cross the line into subject lines that are perceived as garbage. But do throw in a bit of a tease.
- Urgent when it’s useful: When every message from you is urgent, none is. Use urgency when it’s actually useful, such as when there’s a real deadline or compelling reason to act now. If you’re running your email marketing based on value and great offers, people don’t want to miss out and need to know how much time they have.
- Rely on spam checking software: We all know that certain words trigger spam filters, but there’s a lot of confusion out there about which words are the problem. Is it okay to use the word “free” in a subject line? Actually, yes. All reputable email services provide spam checking software as part of the service or as an add-on. Craft your messages with compelling language, let the software do its job, and adjust when you have to.
- Shorter is better: Subject line real estate is valuable, so the more compact your subject line, the better. Don’t forget useful and ultra-specific, but try to compress the fundamentals into the most powerful promise possible.
3. The Secret Sauce:Getting someone to trust you with their email address is not easy.
But if you do gain that initial trust, and more importantly, confirm and grow it, you can write pretty lame subject lines and people will still read your messages. Just as with that ditzy friend from high school who nonetheless always has something interesting to say, trust and substance matter most.
Don’t get me wrong, writing great subject lines combined with the more intimate relationship email represents is much more effective. And you have to get your initial messages read to establish the relationship in the first place. Regardless, your open rates will improve based on the quality of your subject line.
But there’s something special in this jaded digital age about being invited into someone’s email inbox. You just have to over-deliver on the value to ensure you’re a treasured guest who gets invited back.
The inbox can be a stressful place. How do you make it brighter?
