Makes: An email that stands out in a crowded inbox

Recipe: Improve Open Rates
Your subject line and preview text are the most important elements you can improve to influence customers to open your emails.
The subject line catches attention, while the preview text builds curiosity. When these tools are used deliberately together, they reinforce each other to create a clearer, more compelling message that stands out in the inbox and encourages more customers to open your email.


What you need

  • Access to Dotdigital to build email campaigns


Time required

Prep time: 5 minutes Cook time: 2 minutes



What will this help me achieve?

  • Make your emails stand out
  • Increase your open rates


Concepts we’ll be using

  • Personalization: a tool in Dotdigital which lets you use data from Spektrix to tailor your email campaign to each individual customer.
  • INFORMALSALUTATION Data Field: used as personalization to display the first name of the customer if there is one present that is more than one character long.



Prep

Check that your informal salutation field is set up:
  • Log into your Dotdigital account
  • Navigate to settings > contacts > contact data fields> custom data fields
  • Find your informal salutation data field and click properties.
  • If you do not have an informal salutation data field, set one up using the field name: INFORMALSALUTATION
  • Under default text, enter a fall back that will display if a customer doesn't have an informal salutation. If you do not set a fall back, instead you can write messages knowing the field might be blank. For example:
  • With salutation:  “John Your Early access starts now!” 
  • With a fallback: “Friend Your Early access starts now!” 
  • With no fallback set: “Your Early access starts now!” 


Activate

When setting up an email campaign in Dotdigital:
  1. In the Campaign Details section, click the personalization button to add the informal salutation data field to your subject line.
  1. Populate the pre-header text with the line you want to appear beneath your subject line.

3. Send a test email to check that the subject line and preview text appear as you intend. 



Try this twist

Use personalization strategically: Adding a name can increase open rates, but using it in every email can feel automated. Save it for key campaigns such as welcome emails, special offers, or priority booking announcements.
Use preview text as a second headline: Avoid repeating your subject line in your preview text. Instead, use the preview text to expand on the message and give readers an extra reason to open.
