Tips for Writing Effective Email Subject Lines

Crafting effective email subject lines is an art form, but it's not rocket science. With the right strategies and tips, you can create subject lines that grab your recipients' attention, pique their curiosity, and encourage them to open your emails. Here are some tips to help you get started:

A. Using Attention-Grabbing Words

Use powerful, emotionally-charged words to capture your recipients' attention. Words like "free," "new," "limited time," "exclusive," "secret," and "surprise" can be particularly effective.

Using powerful, attention-grabbing words like "free," "new," or "limited time" can make your email subject lines stand out in a crowded inbox. For example, "New Arrival Alert: Get 20% off your first purchase!" is a great subject line that uses both the "new" and "discount" triggers to grab the recipient's attention.

B. Creating a Sense of Urgency

Encourage your recipients to act quickly by creating a sense of urgency in your subject lines. Use phrases like "don't miss out," "last chance," "today only," "hurry," or "limited availability" to create a sense of FOMO (fear of missing out).

Creating a sense of urgency in your subject lines can make your recipients feel they need to open your email immediately. For example, "Hurry! Only 2 days left to claim your free gift!" is a great subject line that uses urgency to encourage recipients to act quickly.

C. Personalizing Subject Lines

Use your recipients' name, location, or other personal details to create more personalized subject lines. This can help your messages feel more relevant and engaging. Strikingly's email campaign tool makes adding personalized fields to your subject lines easy.

Personalizing subject lines with your recipient's name or other details can make them feel like the message was specifically tailored to them. For example, "John, you won't want to miss this exclusive offer!" is a great subject line that uses personalization to create a more engaging message.

D. Asking Questions

Use questions to pique your recipients' curiosity and encourage them to open your email. Questions like "Are you making these common mistakes?" or "Want to know our secret to success?" can be particularly effective. Just make sure the question is relevant to your message.

Asking a question in your subject line can pique your recipients' curiosity and encourage them to open your email to find out the answer. For example, "Are you ready to transform your business in 2022?" is a great subject line that asks a relevant and engaging question.

E. Avoiding Spam Trigger Words

Be mindful of spam trigger words like "money back guarantee," "earn extra cash," "act now," and "credit card." These words can trigger spam filters and cause your emails to get sent straight to the junk folder.

Avoiding spam trigger words like "money back guarantee" or "earn extra cash" can help ensure your email lands in your recipients' inboxes instead of their junk folders. For example, instead of using "earn extra cash" in your subject line, try "Unlock the secret to financial freedom."

F. Using Emojis

Emojis can be a fun and effective way to easily add visual interest to your subject lines. Just be sure to use them sparingly and ensure they're relevant to your message. Strikingly's email campaign tool has a built-in emoji selector, making adding emojis to your subject lines easy.

Using emojis can add a fun and playful touch to your subject lines and make them stand out. For example, "🎉 Don't Miss Our Big Sale Event! 🛍️" is a great subject line that uses emojis to create visual interest and excitement.

G. Using Humor

Don't be afraid to inject a little humor into your subject lines. A funny or clever subject line can help your message stand out in a crowded inbox. Just make sure the humor is appropriate for your audience and your brand.

Using humor can help your subject line stand out in a crowded inbox and make your recipients smile. For example, "Don't Be a Grinch! Get 50% off Your Holiday Shopping 🎁" is a great subject line that uses humor to create a more engaging message.

H. Keep it Short and Sweet

A general rule of thumb for email subject lines is to keep them under 50 characters to ensure they don't get cut off in the inbox preview. However, don't sacrifice clarity for brevity. Make sure your subject line clearly communicates what your email is about.

Keeping your subject lines short and sweet can help ensure they don't get cut off in the inbox preview and make them more easily scannable for busy recipients. For example, "Last Chance: Free Shipping Ends Today!" is a great subject line communicating urgency and brevity.

I. Use Numbers and Lists

People love lists and numbers, so incorporating them into your subject lines can be a great way to grab attention. For example, "5 tips for boosting your sales" or "10 ways to save money on your next vacation."

Using numbers and lists can help break up the text in your subject lines and make them more visually appealing. For example, "7 Surprising Ways to Boost Your Productivity" is a great subject line with a numbered list to create interest and curiosity.

J. Test and Iterate

Don't be afraid to experiment with different types of email subject lines and see what works best for your audience. Use A/B testing to try different subject lines and track their performance over time. This can help you fine-tune your approach and create even more effective email subject lines in the future.

Testing and iterating your email subject lines can help you fine-tune your approach and create even more effective messages over time. For example, you might test two different subject lines - "Introducing Our New Product Line" and "Discover Our Exciting New Products!" - to see which one gets a higher open rate. Testing and iterating can continually improve your email campaigns and drive better results.

Here are 10 more tips for creating an effective email subject line:

1. Be Specific - Use specifics in your subject lines to let your recipients know exactly what to expect. For example, "5 Must-Have Tools for Social Media Success" is a great subject line that clearly communicates the content of the email.

3. Use Power Words - Use power words in your subject lines to create a sense of urgency and importance. For example, "Urgent: Don't Miss Out on This Limited-Time Offer" is a great subject line that uses power words to create urgency.

4. Make it Exclusive - Use exclusivity in your subject lines to make your recipients feel special. For example, "VIP Access: Be the First to Shop Our New Collection" is a great subject line that creates a sense of exclusivity and importance.

5. Use Reverse Psychology - Use reverse psychology in your subject lines to create interest and intrigue. For example, "Ignore This Email at Your Own Peril" is a great subject line that uses reverse psychology to create curiosity.

6. Keep it Conversational - Write your subject lines like you're conversing with your recipient. For example, "Hey there! Ready for Some Amazing Deals?" is a great subject line that feels personal and engaging.

7. Use Urgent Language - Use urgent language in your subject lines to create a sense of immediacy. For example, "Hurry! Our Cyber Monday Sale Ends Tonight" is a great subject line that creates urgency and encourages action.
