What Makes a Media Pitch Subject Line Get Opened, and What Makes One Get Deleted

A media pitch subject line has one job, and being clever is not it. It has to tell a journalist, inside the width of an inbox preview, what the story is and why it belongs to them specifically. Muck Rack's 2026 State of Journalism report, based on a survey of more than a thousand journalists, found that 88% immediately delete pitches that do not match their coverage area, and that half seldom or never reply to pitches at all. Almost all of that filtering happens before a single line of your body copy is read. Here is what actually earns an open, what earns a reply, and why those two things pull in slightly different directions.

Why does the subject line do more work than the rest of the pitch?

Because it is the only part a journalist reads by default. Cision's 2026 State of the Media Report, based on 1,899 journalists across North America, EMEA and APAC, found that most receive 50 or more pitches a week and that 86% will reject one outright when it is not relevant to their beat or audience. That rejection is not the outcome of a careful read. It happens in a preview pane, in about a second, on the strength of roughly eight words.

So a subject line is not a headline for your announcement. It is a relevance test, run by the journalist, on your behalf, in public. If it does not pass, nothing else in the email exists.

What is the difference between a subject line that gets opened and one that gets a reply?

They are different jobs, and the data separates them cleanly. Propel's Media Barometer analysis of pitch performance found that subject lines of six to nine words were opened most often, at 48.83%, while subject lines of one to five words produced the highest response rate, at 4.73%, more than double the response rate of the longest subject lines. Pitches with subject lines of ten to fifteen words were sent most frequently, at 36.54% of everything sent, which tells you most people are optimising for neither.

The reading of that is straightforward. A slightly longer subject line creates enough curiosity to earn a click. A very short one gives a journalist enough to decide without clicking at all, which is why it converts.

In practice: if you are offering something a journalist already wants, an exclusive, a first look, hard news, go short and factual. If the value needs a moment of framing, six to nine words buys the open, but the first sentence of the body then has to finish the job, because you have spent your specificity on the click rather than the decision.

What does a specific subject line actually look like?

The quickest diagnostic I know is to strike out every adjective. If what remains still says what happened, the subject line is working. If what remains is a company name and a verb, it is not. Four before-and-after pairs, all of the type I see most often:

• 'Exciting news from [company]' becomes 'First UK data: a third of night-shift nurses working unpaid hours'. The second names a finding. The first names a mood.

• 'Introducing our new AI platform' becomes 'Trial: AI cuts hospital discharge paperwork by 40%'. Journalists do not cover launches. They cover consequences.

• 'Founder available for interview' becomes 'Ex-Deliveroo engineer on why gig apps keep failing safety audits'. A person only becomes interesting once you say what they can say.

• 'Press release: Series A funding' becomes '£4m to put dementia care rotas on one system'. The money is the least interesting part of a funding round to everyone except you.

One of my own, from the campaign behind The Stolen Son: 'EXCLUSIVE: Stolen at birth, emotional reunion in Chile next week.' Nine words carrying three pieces of information: the offer, the human fact, and the timing. No adjective describing how moving it was, because the facts already were.

Which subject lines get deleted on sight?

• Anything opening with 'Press release:'. It announces that the email contains a document rather than a story, and that nobody has thought about this particular journalist's beat.

• 'Quick question', 'Story idea for you', 'Following up'. Zero information, and 'following up' in particular advertises that the first attempt failed.

• A company name the journalist has never heard of in the first three words. The name means nothing yet, and you have spent your most valuable space establishing that.

• 'EXCLUSIVE' on an email that went to forty people. This is the one that does lasting damage. Journalists talk to each other, and a false exclusive is remembered far longer than a good pitch.

• More than one exclamation mark, or capitals beyond a single flag word such as EXCLUSIVE or EMBARGOED. Anything more reads as marketing, and marketing gets filtered.

• A subject line describing your announcement rather than the story it sits inside. 'We have launched X' is an internal milestone. 'X changes Y for Z people' is a story.

How long should a subject line be, and where does it actually get cut?

Between four and nine words, and short enough to survive a mobile preview. Most journalists triage on a phone, where roughly the first thirty-five to forty characters are visible before the line truncates, which means the decision is often made on the first four or five words alone.

Front-load accordingly. Put the fact in the opening words and the qualifier after it. 'Third of night-shift nurses working unpaid, UK data shows' survives truncation. 'New research from [company] reveals that a third of night-shift nurses...' does not, because everything that matters sits past the cut.

How do you write a subject line for a sensitive story?

Sensitive stories fail in both directions: either so euphemistic that nobody can tell what happened, or so lurid that the story is undermined before it is read. Both come from writing the subject line for effect rather than for accuracy.

The test I apply is whether the person whose story it is would read the subject line and feel accurately described. If yes, it can go. If it turns them into a headline rather than a person, it cannot, regardless of how well it would perform.

Practically that means stating the fact plainly, naming the human stake once, and leaving emotional language out entirely. A journalist covering a sensitive story will find the emotion themselves. What they need from you is confirmation that the story is real, that the person has consented, and that they are able to speak.

What changes when you are offering a genuine exclusive?

Say so, and say what the exclusive actually is. 'EXCLUSIVE' on its own is not an offer, it is a claim. 'Exclusive: first interview with X since Y' is an offer, because it names the thing being given away.

Two rules I hold without exception. One exclusive at a time, and the subject line makes clear which outlet it belongs to. And the deadline goes in the body, never in the subject line. A deadline in the subject line reads as pressure applied by someone who has not yet earned the right to apply it.

How do you test a subject line before you send it?

Six checks, none of which takes longer than a minute:

• Read it in a preview pane on a phone, not in a desktop compose window. That is the format in which it will actually be judged.

• Delete every adjective. If the remainder still states what happened, keep the shorter version.

• Ask whether it makes sense to somebody who has never heard of your company. If it needs your brand as context, rewrite it.

• Check it contains at least one thing the journalist could not already find through a search.

• Check that the first line of the body does not simply repeat it. A repeated subject line wastes the only sentence you have earned.

• Read it aloud. If it sounds like a press release headline, it is one.

What mistakes come up most often?

• Writing the subject line first. It should be written last, once the angle is settled, because you cannot summarise a story you have not yet decided on.

• Using one subject line for the whole list. If the angle is genuinely identical for a trade reporter and a national news desk, it is not sharp enough for either.

• Optimising for opens and then being surprised by the silence. An open with no reply usually means the subject line promised something the body did not deliver.

• Reading a non-reply as a verdict on the story. Half of journalists seldom or never respond to pitches, yet 86% say at least some of their work began with a PR pitch. Silence is the norm, not the judgement.

• Reusing a subject line because it worked once. It worked because it fitted that story, in that week, for that journalist.

The subject line is the smallest piece of a campaign and the one that decides whether any of the rest is ever read. Every subject line I write is drafted last, after the angle is settled. As a Senior Freelance PR Consultant working across the UK, US, Canada and ANZ, I have watched strong stories die in a preview pane because eight words did the wrong job, and modest ones travel a long way because they did the right one.
