Clickbait has its time and place, but you need to tone it down. If a reader feels cheated after opening an email, you need to work on your newsletter subject lines.
Keep three words in mind: Truth in advertising. Make sure your newsletter Subject is a direct reflection of the body of the email. If they are not, edit them until they fit.
3. Uses words that scream “SPAM”
Uses words that scream "SPAM"
Some words are simply a no-no for email subject lines. Words like free, spam, no cost, investment, inventory , cash, stock alerts, and more automatically trigger spam bots.
The best way to avoid trigger word spam is to write as if a normal person were speaking. This will keep you on the right side of spam filters so you don't have to worry about not reaching your subscribers.
4. EVERY WORD IS WRITTEN IN CAPITALS
Large text is uncomfortable for most readers. It's not as easy to read as a sentence or capital letters, and many people perceive it as a written version of shouting.
Sentences work best in most situations. Write newsletter subjects as if you were writing a regular self employed database sentence—punctuation and all. Capitalize the first letter of the sentence, but keep everything else lowercase.
5. Not optimized for mobile users
More than half of all emails sent are opened on mobile devices . That’s incredible. If your newsletter subject lines aren’t optimized for mobile users, you could be losing 55 percent of your audience.
Don't risk it. Keep your newsletter subject line brief and don't use any special characters that mobile operating systems might not be able to read.
Originality is a difficult thing. On the one hand, there is no such thing as true originality. If you think of something, someone else has already thought of it.
But don't let that stop you from getting creative. Focus on creating subject lines that will feel fresh and original to your audience. Consider looking for inspiration in a completely different industry, for example. Then figure out how you can rework it for your audience.
