How to Write Good B2B Email Subject Lines? Do's and Don'ts

Here are some do's and don’ts to help you craft effective B2B email subject lines:

🟩 Do's 

  • Aim for 61-70 characters: Aim for 61-70 characters in your subject line. This length gets the most reads with a rate of 17% (Zippia).
  • Use the word “video”: Subject lines with "video" can get 7 to 13% more opens (Zippia). Therefore, consider adding a video to your email.
  • Use numbers: Adding numbers to your subject line to potentially increase open rates by up to 45% (Yesware).
  • Be personal: Make the subject lines about the reader. Personalized subject lines are 50% more likely to get opened (Marketing Dive).
  • Leverage numbers and lists: Numbers and list-based subject lines can set clear expectations, e.g., "5 Strategies to Improve [Their Brand’s] ROI."
  • Choose professional subject lines: For example, instead of a casual "Hey, check this out!" a more professional "Exclusive Insights for [Company Name]" can resonate better with a business audience. 

🟥 Don'ts 

  • Don't make subject lines too long: A subject line that's too long will get cut off on mobile screens, reducing its impact.
  • Avoid spammy words: Words like "Free," "Guarantee," and pushy sales language can mark your email as spam.
  • Don't overuse special characters and caps: Too many exclamation points, all-caps words, or similar special characters can appear unprofessionally and spammy.
  • Don't be overly salesy: Avoid being too pushy with hard sales on the subject.
  • Don't be generic: Generic subject lines can be a turn-off due to their lack of personalization.
  • Remember to segment your audience: Don't send the same email to everyone. Consider the specific needs of different groups of people when designing your subject lines.

B2B Email Subject Lines for Creating a Sense of Urgency
