Subject: A little room for adventure
Preheader: Meet the new collection, made for the plans you make on Friday.

Make the next step deliberate.

  1. Write the subject

    Say what the message is about without unsupported urgency.

  2. Add the missing context

    Use the preheader to extend rather than repeat the subject.

  3. Compare the pair

    Check narrow and wide illustrative previews; actual client truncation varies.
