Other tips:

  • Keep it simple and honest.
  • Be clear and descriptive rather than creative. Creativity can result in ambiguity.
  • Inform rather than sell.
  • If you know who the recipient is, try to think what could be effective for him.
  • Write the subject after writing the email, as youd do with the title of an article.
  • Before sending the email, read the subject again: does it explain the content? Is it a short summary of the text? If not, then write it again.
  • Test. Try different subjects and verify which works better.

  • When contacting someone for a brand mention, writing the title of the article as the subject line tends to work well. Especially if the article is recent.
  • When contacting someone for a guest post, use the words collaboration or article proposal.
  • When contacting an educational or university site offering a position, just name the role with the words position or offer and the name of the client.
  • Dont name the client if you are not sure the recipient will know them.
  • A descriptive tone is always the best. Creative texts could be misunderstood or considered too commercial.
