5 Tips to Improve Your Subject Lines
It can be frustrating and annoying that email open rates are lower than average. So it never hurts to quickly recap top tips and industry best practise to help keep your subject lines performing well.
TIP 1: Length
The number 1 tip to help improve your next subject line is to
Keep it short !
It is always tempting to try and pack everything into the subject line, thinking that this is all a person might read. This might be true, but all email clients, such as Outlook or Gmail only allow for an average of 40 characters to be displayed anyway. Everything after this is hidden until after the email is opened. For example:
“Free webinar: Learn how to mitigate against unavoidable revenue loss with our revenue assurance service“
“Free webinar: Learn how to mitigate agai…“
Make sure the first 40 characters count !
TIP 2: Use Keywords
Since your message must be short, it’s imperative you focus on
Keywords of interest
People skim through subject lines, bland words that are essentially padding are a poor use of your 40 characters. If you know the subject area, you should know critical keywords. If you don’t – Google is your friend. In our example, googling “lost revenue” brings up:
“Profit, Loss and Sales”.
Good candidates to use as “eye magnets” in the subject line.
TIP 3: Urgency
You want your reader to open your email NOW. If its unread for 24 hours, it will likely never be read.
Without a sense of needing to act quickly, the email will drop down the readers mental priority list. Having a time limit is important to encourage action.
Create a deadline
Tomorrow, 24 hours left, last chance are all good ways to stimulate a sense of urgency.
TIP 4: Fear of Missing Out
The fear of missing out is more powerful than the thought of receiving something good. For example:
- Something good: “Revenue assurance can mitigate sales loses”.
- FOMO: “CFOs are protecting themselves against sales loses”.
Immediately a reader is curious HOW the CFO is protecting themselves and doesn’t want to miss the chance to do the same.
Fear is more powerful that safety
TIP 5: A/B Testing
Keep it short, use keywords, create urgency and a fear of missing out. But sometimes, an audience can behave in unexpected ways.
No two audiences are the same
This is why A/B testing is absolutely critical to any campaign. Test different keywords, an urgent message and a non-urgent one. Test fear and a positive message.
On average, our tips are correct, but maybe your audience is weird , so always test, review and test again.
