    • If a trigger send is necessary, please send 2 subject lines with materials.

  • Best Practices:

    • Standard template width is 600px

    • Place a stealth link within your HTML code to reduce unwanted clicks. Learn more here

    • An email made entirely of images is not recommended because email platforms may block the images

    • An HTML email should be a balanced combination of text and images, with a clear call to action.

    • We do not recommend using emojis in subject lines or email content as this can lead to delivery challenges.
