Free message checker

Check your message before you send it.

Paste a cold email, a LinkedIn connection note or a LinkedIn message after they accept. Tick checks it against the rules Day60 uses on every draft and tells you what to fix.

What are you sending?

The rules Tick checks

Day60 checks every draft against these rules before you see it. The checker above uses the same ones, in your browser.

Cold email

  • Short subject line

  • Doesn’t start with “I”

    Starting with them, not you, shows you know who you’re writing to.

  • Asks one clear question

    One clear question is easy to answer, and just as easy to say no to.

  • The question comes last

    Ending on your question leaves them one clear thing to answer.

  • Fits the length limit

  • Keeps to a few sentences

    That’s room for one detail about them, one example from your work and one question.

  • Ends with a sign-off and the “not me” line

    The “not me” line gives the wrong person an easy, polite way to say so.

  • At most one em dash

    More than one in a short message can make it sound like a bot wrote it.

  • No overused phrases

    These show up in so many messages that readers skim past them.

  • No private details

  • Plain text only

  • No links

  • No attachments

LinkedIn connection note

  • Doesn’t start with “I”

    Starting with them, not you, shows you know who you’re writing to.

  • Asks one clear question

    One clear question is easy to answer, and just as easy to say no to.

  • The question comes last

    Ending on your question leaves them one clear thing to answer.

  • Fits the length limit

  • No sign-off

    LinkedIn already shows your name with it.

  • At most one em dash

    More than one in a short message can make it sound like a bot wrote it.

  • No overused phrases

    These show up in so many messages that readers skim past them.

  • No private details

LinkedIn message after they accept

  • No overused phrases

    These show up in so many messages that readers skim past them.

  • No private details

How long each message can be

  • Cold email: a subject of 3–7 words, and 75–175 words in all, with 4–6 sentences before your sign-off and the “not me” line.
  • LinkedIn connection note: under 300 characters. Keep a version under 200 for free accounts.
  • LinkedIn message after they accept: under 700 characters, in 3–5 sentences.

The limits keep you to what matters: one detail about them, one example from your work and one question.
