Common Mistakes to Avoid
Writing the perfect email subject line requires more than just following email subject lines best practices. To truly excel, it’s essential to recognize and avoid common pitfalls. Here are some examples:
1. Overusing Exclamation Points
Overusing exclamation points can make your subject line appear unprofessional and overly sensational. It can also trigger spam filters, reducing your email’s deliverability.
– Alternatives: Instead of relying on exclamation points to convey excitement or urgency, use strong action words and persuasive language. For example, instead of “Limited Time Offer!!!”, try “Exclusive Offer Ending Soon”.
2. Writing Clickbait-y Email Subject Lines
Clickbait subject lines can increase your open rates temporarily, but they often lead to disappointment and distrust among your subscribers when the email content doesn’t match the subject line’s promise.
– Balancing Curiosity and Transparency: To maintain trust, craft subject lines that pique curiosity without being deceptive. Ensure that your subject line accurately reflects the email content. For example, instead of “You Won’t Believe This Shocking News”, try “Discover the Latest Updates in Our Industry”.
3. Using Spammy Language
Certain words and phrases like “Free”, “Urgent”, “Buy Now”, and excessive use of capital letters can trigger spam filters. These can result in your emails being directed to the spam folder rather than the inbox.
Alternatives: Use more natural and conversational language to avoid spam triggers. For instance, instead of “FREE Gift Inside”, try “A Special Gift Just for You”.
4. Ignoring Mobile Optimization
A lot of emails are opened on mobile devices, making mobile optimization important.
– Tips for Mobile-Friendly Subject Lines: To ensure your subject lines are mobile-friendly, keep them concise and place the most important information at the beginning. Avoid excessive punctuation and complex words that might get truncated on smaller screens.
5. Neglecting Subject Line Length
Subject lines that are too long can get cut off, especially on mobile devices, while those that are too short might not provide enough information to entice the reader.
