How to Write a "Why Now" Line That Gets Replies
A why-now line is the one sentence that explains why you're writing today. A simple formula, examples by signal, and mistakes to avoid in cold email.

A "why now" line is the one sentence in a cold email that explains why you're writing to this company this week rather than any other week. A good one names a specific, recent and checkable event, connects it to a problem that event usually creates, and points to how you help. If you can't write it in one plain sentence, the signal probably isn't strong enough to act on.
Most cold emails answer "who are you?" and "what do you sell?". Few answer the reader's real question: "why is this in my inbox today?" Without that, even a well-targeted email reads like a mass send.
What a "why now" line is (and isn't)
A why-now line is a bridge between something that just happened at the company and the problem you solve, written so the reader recognises it as true for them.
It is not:
- A compliment. "Love what you're building" tells the reader nothing about why you're writing.
- A congratulations. "Congrats on the raise" is the sentence every other vendor sent the same morning.
- A data dump. "I noticed you posted 14 roles, changed directors and moved office" proves you looked, not that you understand.
- Your pitch. The why-now line earns the right to pitch. It isn't the pitch itself.
If you're new to the idea of signals, start with our guide to what buying signals are. This post assumes you've already spotted one and need to turn it into words.
The formula: event, implication, offer
Every strong why-now line has three parts, even when they're squeezed into one sentence.
- Event. Something specific, recent and checkable. "You're hiring your first two sales reps" is an event. "You're growing" isn't.
- Implication. The problem that event usually brings with it. This is where you show you understand their world, not just their news.
- Offer. A short pointer to how you help with that problem. One clause, not a paragraph.
Put together:
"Saw you're hiring your first two sales reps. Teams at that stage often find the founder's pipeline doesn't stretch to three people, which is the gap we help fill."
The rest of the email can be two or three sentences and one question.
Test it before you send it
Run every why-now line through four quick checks:
- Specific: could this sentence be sent to any other company? If yes, rewrite it.
- Recent: did it happen in the last few weeks?
- Checkable: could the reader see where you found it? If not, it sounds like surveillance.
- Relevant: does the implication lead to what you sell without a stretch?
Examples by signal
Here's how the formula works for the four signal types Outrun watches.
Job posts
Job ads say which team is growing and what the new hire will own, so the company has described its own problem for you.
- Weak: "Saw you're hiring. Would love to chat."
- Better: "Saw the new head of finance role mentions 'building our reporting from scratch'. That first quarter of setup is usually where [your product] saves the most time."
For which roles point to which products, see hiring signals: using job posts to time outbound.
Funding and news
A raise means new budget and a plan, but every vendor reads the same announcement. Skip the congratulations and lead with what the money is for.
- Weak: "Congrats on the Series A!"
- Better: "Your announcement said the round is going into US expansion. Hiring a first team in a new market usually means [problem you solve] gets urgent fast."
Our guides on why funding rounds are the best time to reach out and finding companies that just raised go deeper on timing.
Public X posts
When someone posts publicly about a problem, the line almost writes itself. The risk is sounding like you've been watching them, so keep it light.
- Weak: "I've been following your posts and saw your thread from Tuesday..."
- Better: "Saw your post about onboarding taking longer than the build. We help small teams cut that down, happy to share what's worked if useful."
Companies House
For UK companies, the public register shows changes companies must report by law. New directors must be reported within 14 days, and new share issues within a month. That makes it a dependable timing source, but form numbers make terrible openers.
- Weak: "I noticed your AP01 filing last week."
- Better: "Saw you've brought in a new operations director. New leaders often review suppliers in their first few months, so I thought I'd introduce [what you do] early."
If a share issue suggests a round that was never announced, don't mention it. Use it to decide when to write, then lead with a relevant problem. Our Companies House for sales guide covers which filings are worth watching.
Mistakes that make a good signal fall flat
Leading with the signal instead of the problem
The signal is why you're writing; the problem is why they'd reply. All event and no implication leaves the reader to work out why it matters.
Stacking every signal you found
Three clauses of evidence feel like a dossier. Open with the most relevant signal and save the others for your follow-up.
Waiting too long
A line about a job post that closed a month ago undoes itself. Act within days of spotting a signal, or find a fresher reason.
Writing to the wrong person
A strong line sent to someone who doesn't own the problem goes nowhere. Connect the event to the person who owns the problem, usually the founder or the head of the team that's changing. Our ICP template includes the buyer roles to aim for.
Forgetting the basics
A great opening doesn't excuse a poor email. In the UK, the ICO's guidance on business-to-business marketing says B2B emails to companies must not disguise who is sending them and must give a valid address to opt out, and UK GDPR still applies when you're emailing a named person. On the delivery side, Google's email sender guidelines say everyone sending to personal Gmail addresses must set up SPF or DKIM authentication. Neither will write your why-now line, but both decide whether anyone reads it.
A quick template you can copy
Subject: [the event, in plain words] Hi [name], [Event: what you saw and where]. [Implication: the problem that usually follows]. [Offer: one line on how you help with that problem]. Worth a 15-minute chat, or should I send a short example instead? [Your name] [How to opt out]
Keep it short. If the why-now line is right, it does most of the work.
Getting the why-now line written for you
Writing the line takes minutes. Finding the signal behind it takes much longer: checking job boards, funding news, public X posts and Companies House every morning, then working out which companies fit your ICP.
That's the part Outrun does. You set your ICP once, and every weekday morning at 7am in your timezone you get a digest of leads showing a fresh buying signal, in your inbox (or Slack/Telegram on Growth and up). Each lead comes with a why-now line and a link to the public source, so you can check the event and rewrite the line in your own voice. Emails are labelled "Confirmed" when verified or "Confident" when likely right but not yet verified. Rating leads in the Outrun app refines your ICP, so the next digest fits better.
Plans start at £19 a month for up to 5 leads a day, with a 7-day free trial (card required, cancel before it ends and you pay nothing). If you'd like tomorrow's why-now lines written before your first coffee, start your trial at outrun.so.
FAQ
What is a "why now" line in a cold email?
A why-now line is the sentence that explains why you're contacting a company at this moment. It names a recent, specific event, such as a new job post, a funding round or a new director, and links it to a problem you help solve.
How long should a why-now line be?
One sentence, two at most. It should cover the event, the problem that event usually creates, and a brief pointer to how you help. If it needs a paragraph, the connection between the signal and your product is probably too weak.
Should I mention a company's funding round in a cold email?
Only if it was publicly announced, and even then, skip the congratulations. Lead with what the company said the money is for and the problem that plan creates. If a raise only shows up in filings, use it for timing and don't mention it.
How recent does a buying signal need to be?
As recent as possible. Aim to act within days of an event, not weeks. An email about a job post that has already closed, or a round from months ago, suggests you're working from an old list.
Is it creepy to reference what a company posted publicly?
It can be if you overdo it. Reference the change or the topic, not the paperwork or a list of someone's posts. Keep it to one relevant detail the reader would expect a business contact to notice, and make it easy for them to opt out.
