Do's and Don'ts

Here are some key do's and don'ts when choosing a subject line for a thank you email:

Do's:

• Be Expressive: Use subject lines that express genuine gratitude and enthusiasm, such as "Heartfelt Thanks for Your Support" or "We're Grateful for Your Help."
• Personalization: Whenever possible, personalize the subject line with the recipient's name or specific details about their support, like "Thank You, [Recipient's Name], for Your Valuable Advice."
• Clarity: Ensure that your subject line clearly conveys the purpose of the email. For example, "Thank You for Your Mentorship" is straightforward and to the point.
• Highlight Benefits: If applicable, mention the positive impact of the recipient's actions, like "Your Support is Fueling Our Growth."
• Incorporate Emotion: Use words that evoke positive emotions, like "Gratitude," "Appreciation," or "Celebration."
• Keep it Concise: Use short, concise subject lines to grab attention without overwhelming, such as "Big Thanks!" or "We Appreciate You!"
• Automate: Use ConvertKit to automate your thank you emails and personalize the subject line for each recipient.

Don'ts:

• Avoid Overly Formal Language: Don't make the subject line too formal or stiff. Instead, aim for a friendly and approachable tone.
• Avoid Jargon: Steer clear of industry-specific jargon that may not be easily understood by everyone.
• Don't Make It Too Long: Long subject lines can get cut off in email previews. Keep it brief and to the point.
• Refrain from Generic Phrases: Avoid generic phrases like "Thank You for Your Time" or "Your Support is Appreciated." These lack personalization and impact.
• Don't Sound Transactional: Make sure your subject line doesn't come across as purely transactional. Instead, focus on building a meaningful connection.
• Don't Overdo Punctuation or Emojis: While a well-placed emoji can add a friendly touch, too many or excessive punctuation (!!!) can appear spammy or unprofessional.
