Use Preheader Text Option

Preheader text, often referred to as the email preview text, is a short summary text that follows the subject line when an email is viewed in the inbox. It’s the first line of text visible from the email content and plays a crucial role in influencing the recipient’s decision to open the email.

Purpose of Preheader Text

  1. Increases Open Rates: Preheader text works alongside the subject line to provide a compelling reason for recipients to open the email. It gives a sneak peek into the email’s content, encouraging more opens.
  2. Enhances Email Effectiveness: By carefully crafting this text, you can make your email stand out in a crowded inbox and give recipients an immediate understanding of the email’s value.
  3. Blocks Out Less Relevant Body Text: Without a specific preheader, email clients may display the first few lines of the email body as default preview text, which might not be as engaging or relevant.
  4. Provides Context: It offers additional context or complements the subject line, making the overall message more appealing.
