Avoid using ALL CAPS


Avoid making false promises:

  • Do not make false promises in the subject line and deviate from them in the email body content. This is called clickbait and is usually frowned upon.

Include Numbers and Lists:

  • Try to add numbers and values wherever possible to attract readers. You can mention the discount value or use numbers to refer to the size of your listicle.

Make the recipient feel special:

Choose sentences that instantly grab the attention of the recipient and make them feel special. Here are some great examples:

  • “You’re invited!”
  • “For our beloved customers only”
  • “An exclusive offer for you”

Segment your best email subject lines:

  • Age range
  • Industry
  • Geography
  • Job
  • Behaviours

Then customize the subject line based on this trait to make it more relevant.

Catchy email subject lines:

  • I got ANOTHER sweet clean FREEBIE for you!
  • This is not another COVID email, {$name|default:”friend”}! It’s good news!
  • [Freebie Friday] So many secrets…
  • Welcome to your next escape
  • I have a feeling YOU will love this!
  • Happy Friday + Surprise Inside!?
  • Are you an early bird?
  • Did you invest in a financial product that wasn’t great?
  • There are literally 101 free books in this email
  • Life happens. And so do giveaways.

Make Customers Feel ‘Exclusive’

  • “Exclusive gift”
  • “Free Goodies”
  • “Special Invitation”
  • “Insider Appearance”
  • “private invitation”
  • “Discount just for you”
  • “To our esteemed customers”

Say more for less:

  • Keep your titles short. In fact, 28 to 39 characters in the subject line achieve the highest email visibility because more people read emails on the phone and cannot see all emails if the subject is too long.

Honesty is the best policy:

  • lying or misleading with titles is not a good idea. Even if you increase your open rate for certain emails, you may annoy your recipients and delete them without opening future emails or simply unsubscribe.

Use Questions to Seek Attention:

  • “Are you making these SEO mistakes?”
  • “Do you know what went wrong with your website?”

Mention a mutual connection:

  • “[Mutual contact] mentioned you”
  • “Hello – [Name], [Mutual Contact] said we should connect”
  • “I saw you in [Shared interest / social group]. Can we connect? “
  • “Hello, [name], we met at [conference / event].”

Thank you email subject lines:

  • We are so thankful for YOU
  • Thank You for Saying YES!
  • Dearest,{$name} Thank You for your love and support on my New Novel!
  • Thank you for sticking with me! Check inside for a special giveaway!

  • Here’s a little thank you present for sticking with me…
  • Thanks for signing up! **Attention required so you don’t miss a thing!**
  • Welcome! Here’s a little FREEBIE to say thank you for joining the fun!

Wrap up:

  • Use a few of the words that are proven to increase open rates.
  • Avoid the terms that typically decrease open rates.
  • Test using a number in your subject line.
  • Include at least one emoji.
  • Make it about 17-24 characters long.
  • Shoot for approximately 3-5 words.
  • Write it in title case.
  • Utilize preheader text.
  • Learn from other companies.
  • You’ve got this.

When writing subject lines for your emails, keep it engaging, simple, and on-brand. Don’t forget to appeal to the emotions and needs of your target buyers, and most importantly, have fun — include emojis, puns, or references to pop culture. Your emails will get opened, guaranteed.
