Cold email subject lines that get opened

Good cold email subject lines are short, specific to the reader and sound like a colleague wrote them. The strongest real examples name a trigger, like an award, or connect two companies, like Healthgrades to Lavender. Avoid hype and fake replies. Only use a line like voicemail if you actually left one.

Which real examples show it

Use a public award as the trigger
Ideal Candidate

1. Use a public award as the trigger

The subject line is about the reader, so it gets opened. The trigger gives a believable reason for the email right now. Josh Braun notes it still lacked a follow up.

  1. Watch for awards, funding or press about the prospect
  2. Put the congratulations in the subject line
  3. Connect the event to a likely need
  4. Name customers like them
  5. Follow up, which this sender did not

Write three lines for three jobs

2. Write three lines for three jobs

It is short enough to read on a phone, starts from the reader's world, and the ask is easy to say yes to.

  1. Write a problem line from what you know about them
  2. Explain your fix in one or two lines
  3. Ask an interest question, not for a meeting
  4. Keep each block to three lines on mobile
  5. Avoid commas and long words

  1. Track champions who change jobs
  2. Subject line: old company to new company
  3. Congratulate first
  4. Remind them why they bought before
  5. Ask for time a few weeks out

4. End a sequence with a polite breakup

Tentative wording and an easy way to say no often draw the truth, and the PS asks for a referral.

  1. Acknowledge you have not heard back
  2. Restate the reason you reached out
  3. Invite them to correct you
  4. Say you will stop for now
  5. Ask if someone else owns it

5. Give a quiet prospect multiple choice answers

Replying takes one keystroke, and option C gives permission to say no, which makes any answer easier than silence.

  1. Call first and leave a voicemail about the outcome
  2. Use voicemail as the subject only if you left one
  3. Restate the result they wanted
  4. Offer lettered options including a clear no
  5. Keep the tone light and human

Follow up once in the same thread
Beyond the Chaos

A short bump in the same thread keeps the context in view. Josh Braun's teardown also shows how much shorter the first email could have been.

  1. Open with a sincere compliment
  2. Name one benefit for them
  3. Ask one clear question
  4. Wait about a week
  5. Bump in the same thread with the same ask in one line

What else do people ask

How long should a cold email subject line be

A few words. Every real example here is short enough to read at a glance on a phone.

Should I use the prospect's name in the subject

It can help, but a specific trigger or company pairing tells them more about why you wrote.

Is it OK to start with Re

Not on a first email. It reads as a trick. Use Re only when you reply in a real thread.
