Some other tips to remember.

  1. Writing subject lines for email should include: thoughtful creativity, keywords, a sense of urgency, value points, benefit words and emotional triggers.
  2. Don’t repeat your subject line, just because you think it’s a campaign. Your readers may not know that. They could think it’s something stuck in the pipeline and likely trash it. Instead, if it’s a campaign or you have branded your series, add a number, a keyword tied to benefit or hot topic phrase.
  3. Test. Split your list and try a couple variations.
