How PR Agencies Get Clients: An Outbound Plan for Retainers

PR agencies get clients from referrals, the founder's network, awards, published work and outbound. Outbound is the only one of these you control. It works when you pick a narrow group of buyers and write to them right after something changes at their company. The first message asks for a short call. The retainer comes later.

Your buyers: founders, CMOs, heads of communications. Your reason to write: a funding round, a launch, a new executive, a story already moving.

Referrals bring the warmest clients. SparkToro's 2025 survey of digital agencies found that referrals from existing and past clients are by far the biggest driver of new business, the same as in 2024. But referrals arrive on someone else's schedule. A happy client mentions you when it occurs to them.

If you just lost a retainer, you cannot wait for that. Outbound gives you a calendar you set yourself: a steady flow of conversations with people who can sign.

Retainers are also where PR gets hard. In ICCO's World PR Report 2024-2025, the challenge PR professionals named most often was "clients unwilling to commit sufficient funds," at 37% (summary of the ICCO report). The same respondents ranked proactive corporate reputation first among client objectives (61%), ahead of increased sales (46%).

That is agencies describing their own clients, so read it with some caution. Still, it points to a real tension: buyers want the work that is hardest to measure, then hesitate to fund it month after month.

What proof do you need before you send anything?

Anyone who gets your message checks you before replying. A PR agency gets a harder look than most, because you are offering to manage their reputation while they inspect yours.

Start with the profile you send from. It should read like a page written for clients: who you help, what you do for them, and one result with a number. A career summary does not do that job. Zero recommendations is a warning sign, because a recommendation is proof a stranger can check in seconds.

An average message from a strong profile will beat a perfect message from an empty one. Case studies only matter once the reader takes you seriously, so fix the profile before you polish the deck.

We sent the same message for two companies. One got 2% replies. The other got 7.5%. Only the sender changed.

Proof can come from a neighboring field. A CMO buying launch PR can still read a strong social media result for a similar B2B company as relevant, because the buyer and the problem overlap.

The closest case I can share comes from a UK social media marketing agency, a service that sits next door to PR and sells on the same retainer-style deal.

Through LinkedIn outreach, warm emails and cold email across 3 niches, it booked 44 sales calls in month 1, 57 in month 2 and 68 in month 3, and 714 over 12 months. Those were booked meetings, and the agency still had to close them.

Who should a PR agency target first?

Look at the retainers you already hold. For each one, note the person who signed and the size of the company. Then note what was happening there that month. That list is your first target profile, and you build outward from it. The signer is often someone you did not expect, so take the title from the signed contract.

For PR, the signer usually sits in one of three seats:

1. Founder or CEO, at companies small enough that the founder still owns the story and the budget.
2. CMO or VP of marketing, where PR reports into marketing and has to show some link to pipeline.
3. Head or VP of communications, at companies large enough to run comms in-house and buy agency support on top.

Choose one seat and one type of company. Search for the titles that actually sign in that niche, and strip out the ones that rarely hold budget, such as assistant, associate and plain "manager".

Then narrow what you sell. An agency offering media relations, crisis work, content, events and influencer programs to every industry has nothing specific to say in a first message. Pick one service for one kind of company and give it 12 months before you judge it.

A message written for everyone lands with no one in particular. Narrow the offer, but keep the list big. Writing to 50-100 "perfect fit" companies a month turns outreach into a coin flip: in any given week, those people are busy, not ready or simply not interested. Volume negates luck.

Here is what a narrow line could look like, as illustrations rather than client cases:

• launch PR for B2B software companies after a funding round, sold to the CMO
• executive visibility for fintech founders preparing a raise
• reputation support for medical device makers, sold to the head of communications

What should the first message say when PR results are hard to measure?

Nobody signs a PR retainer from an email. They read it, look you up and decide later. So the first message has one job: earn a short call.

Pitching the retainer up front gets you ignored fast. The call costs you nothing, yet it costs the buyer half an hour of a busy week. The message has to make that half hour look worth giving.

A first message for PR has four parts:

1. The trigger: one line on what just happened at their company.
2. The consequence: what that event usually means for their communications, in plain words.
3. One proof line: a result for a client like them, with a number if you have one, written into the message itself.
4. The ask: a short call about that specific situation.

Measurement is where PR outreach goes wrong. Promise a count of placements or clippings in your first message, and the buyer will judge the whole retainer on that count later. Coverage counts rarely show why the company is better off.

Write about the situation the buyer already worries about. Maybe a launch has to reach the right customers before a trade show. Maybe a competitor gets quoted every week and they never do. A CMO recognizes outcomes like these without a dashboard.

How is selling a retainer different from selling a project?

The math shows why that first call carries so much weight. If a client stays 12 months, you collect 12 monthly fees from one sale and one sales cycle. Matching that with projects priced at one month's fee each takes 12 separate wins.

Most agencies want that model. SparkToro's 2025 State of Digital Agencies survey found 85% of agencies prefer to work on a retainer basis, up from 81% in 2024. But 12 months is not a given. In the same survey, 25% of agencies said a typical client engagement lasts less than 12 months, while most work with clients for at least two years.

A paid project can still open the door: a launch sprint with a clear end, then a proposal to continue. When retainer outreach stalls, look at how the offer is packaged before you change tactics. You might not have a lead problem. You might have a packaging problem. Once the offer is clear, the same volume and the same effort start producing calls.

Which news triggers to use, and when to skip the news

A trigger makes the message timely and shows you looked at the company. The harder decision is whether to mention it at all.

Open on the news when the event is public and recent, and it creates a communications job your buyer owns. Open on a reputation or advisory angle when nothing has happened lately, or when the event is one they would rather you had missed.

Spencer Stuart's 2026 CMO tenure snapshot put average CMO tenure at S&P 500 companies at 4.1 years, versus 5.0 years for all C-suite roles. A CMO on a shorter clock than the rest of the C-suite has every reason to look again at the agencies they inherited.

Once an event is more than a few weeks old, it has stopped being news to them. Drop the hook and use the advisory angle.

How should the outreach be sequenced?

Conversations come before calls, and calls come before clients. One message that asks straight for a meeting is a lottery ticket. PR buyers get plenty of those from other agencies, and they ignore them.

Where you can, let a LinkedIn touch come before the email, so the inbox is not where they meet you first. A warm email here means an email to someone who already knows your name from LinkedIn. A typical order:

1. A connection request with a one-line note on the trigger.
2. After they accept, a short message: trigger, consequence, question.
3. A warm email that continues the thread, for people who accepted but stayed quiet.
4. A follow-up that carries the proof line.
5. A follow-up with the other angle: advisory if you opened on news, or news if something new has happened since.
6. A short, polite close-out.

People who never accept the connection go into a separate cold email track with a shorter sequence. Plan on five or six touches across channels, because one or two messages never get a fair hearing. In our campaigns, the third follow-up usually does the most work, provided real time passes before you send it.

The connection-first route can carry serious volume for a service business. For a US business consulting and coaching firm we worked with, 38 of 98 LinkedIn connection requests were accepted (39%). Its calls grew every month: 27, then 35, then 64, and it reached 204 booked sales meetings across the first 4 months.

What has to be ready before the first send?

According to the FTC's guide, CAN-SPAM covers all commercial email, B2B messages included. The guide sets the penalty at up to $53,088 for each email that breaks the law. It also says that the company being promoted and the company sending can both be held responsible (FTC CAN-SPAM compliance guide).

The FTC adjusts that cap for inflation. Its 2025 update raised it from $51,744, effective January 17, 2025. Check the current guide before you rely on the number, and treat this as general information, not legal advice (FTC press release on 2025 civil penalty amounts).

Run this check before the first message goes out:

1. Every address verified before it enters a campaign, with the bounce rate held under 0.5%.
2. Separate sending domains, never your main company domain.
3. SPF, DKIM and DMARC records set on each domain before any volume.
4. New inboxes warmed up for 10 to 14 days before any prospect sees them.
5. Honest header information: From, To, Reply-To and routing.
6. A subject line that reflects what the email actually says.
7. Clear identification of the message as an ad.
8. A valid physical postal address in every email.
9. A clear opt-out, honored within 10 business days, with every opted-out address kept on an exclusion list.

Items 5 to 9 come from the FTC guide. Items 1 to 4 keep you out of spam folders.

How do you know outbound is working for a PR agency?

Track four numbers each week: messages sent, replies, booked calls and signed retainers. The step where the numbers drop tells you what to fix.

Give it time before you pass a verdict. Booked calls can arrive in the first 30 days after launch, but a PR retainer has its own buying cycle. B2B deals often take 6, 9 or 12 months to close, so a call from month 1 can turn into a signed retainer 4 or more months later.

I recommend at least 3 months of data before any decision, and outbound usually needs about 6 months to run at full strength. The social media agency above booked more calls in each of its first 3 months.

When something is off, the numbers point to the cause:

1. Plenty sent, almost no replies after a full sequence to a clean list: change the audience or the offer before you touch the copy. Good copy cannot rescue a bad list.
2. Replies but few calls: the ask is too big or the trigger too weak. Change one variable per test and keep testing until one version wins.
3. Calls but few retainers: the problem sits after outbound. Booking a call and closing it are separate skills, and a weak close rate drops further once colder calls arrive. Count the calls that went nowhere, not just the 2 or 3 retainers you signed. Fix the sales conversation before you buy more volume.
4. Small numbers converting at every step: now add accounts and volume. A funnel that fails at 500 messages will fail at 5,000 too.

Start with the retainer you already hold

Open the contract of your best current retainer. Write down who signed, how big the company was and what had just happened there that month. That is your first buyer, your first trigger and your first message. Run it for at least 3 months before you judge it.

Fix the funnel first. Then scale.
