Short answer: If you are working out how to get clients for a marketing agency, there are four channels that matter: referrals, partnerships, content, and outbound. Referrals close the easiest but you cannot turn them up. Content compounds but takes a long time. Outbound is the one channel where you choose who hears about you and when, which is why most agencies add it once referrals stop being enough.
- Best close rate: referrals and partner introductions, because trust arrives with the lead.
- Most control: outbound, because you pick the companies and the timing.
- Biggest mistake: relying on one channel, usually referrals, until a slow quarter exposes it.
This guide is written for agency owners. It covers what each channel really asks of you, so you can decide where to put your own time and what to hand to someone else.
How do marketing agencies get clients?
Almost every agency starts the same way. The first clients come from people the founder already knows: a former employer, a friend with a business, a contact from a networking group. That works until the network runs out. After that, the agency has to build at least one channel that brings in strangers.
The four channels below behave very differently. Some cost money, some cost time, and some cost patience.
| Channel | What it costs you | Main limit |
|---|---|---|
| Referrals | Good work, asking | Unpredictable volume |
| Partnerships | Relationship time | Slow to build |
| Content | Writing, patience | Slow to pay off |
| Outbound | Money or hours | Needs a clear offer |
Are referrals enough to grow an agency?
Referrals are the best leads an agency gets. The prospect already trusts you because someone they trust said so. Sales calls are shorter, price pushback is lighter, and the client usually stays longer.
The problem is control. You cannot decide to get five referrals next month. You also cannot choose who gets referred. A happy plumbing client will send you other trades, even if you have decided you want to work with software companies. An agency that lives only on referrals grows at the speed and in the direction its clients happen to talk.
You can improve the odds without making it awkward:
- Ask at the right moment. Right after a good result or a kind email, not at invoice time.
- Be specific. “Do you know another dental practice owner who is unhappy with their website?” gets more answers than “send people my way.”
- Make it easy. Offer to write the short intro email for them to forward.
Do these things, and still treat referrals as a bonus, not a plan.
Do partnerships work for getting digital marketing clients?
A partnership is a referral source you build on purpose. The idea is to find businesses that serve the same clients you want and do not compete with you. A web design shop partners with a copywriter. An SEO agency partners with a paid ads agency. A branding studio partners with a printer. Each sends the other work it does not do.
Good partners can become the steadiest source of digital marketing clients you have. The catch is that partnerships are slow. A partner has to trust that you will not embarrass them in front of their client, and that trust comes from doing a few jobs together. Expect to invest in several relationships to end up with one or two that send work regularly.
White label work is a version of this. You do the work under another agency’s name. It fills capacity, but margins are thinner and the client relationship belongs to someone else.
Does content bring in marketing clients?
Yes, eventually. Content means articles, case studies, videos, talks, and anything else that lets a buyer find you and judge your thinking before they speak to you. A buyer who has read three of your articles arrives at the first call half sold.
There are two honest warnings. First, content takes a long time to produce leads, and for the first stretch it produces nothing you can measure. Second, agencies are bad at doing their own marketing. Client work always wins the calendar, so the blog goes quiet for months. Content only works if someone owns it and it ships on a schedule.
Content also works better narrow than broad. “Marketing tips” competes with everyone. “How roofing companies should think about their service area pages” speaks to a buyer you can actually win.
Where does outbound fit in lead generation for marketing agencies?
Outbound means contacting companies that have not heard of you. For most agencies that means cold email, sometimes alongside calls or social messages. It is the only channel of the four where you choose the exact companies, the exact people, and the week they hear from you.
That control is the reason outbound matters in lead generation for marketing agencies. If you have decided to specialise in a niche, outbound lets you reach that niche now, instead of waiting for referrals and search traffic to drift that way.
Outbound has conditions. It works when:
- You know who you serve. “Any business that needs marketing” cannot be turned into a list. “Independent veterinary clinics with two or more locations” can.
- You have a specific offer. A stranger will not reply to “we do full service marketing.” They may reply to one clear problem you fix.
- Someone answers replies quickly. An interested reply that waits three days is usually lost.
- The deal is big enough. Outbound has a real cost per conversation, so it suits retainers and projects, not small one-off jobs.
It fails when the agency treats it as a volume game and sends the same generic pitch to everyone. Marketing decision makers get a lot of cold email from agencies. The ones that get answered are short, specific to the reader’s business, and ask for a small next step.
Should you run outbound yourself or outsource it?
Running cold email yourself means buying sending domains, setting up and warming inboxes, building and verifying a list, writing the sequence, watching deliverability, and handling replies. None of it is beyond an agency owner. All of it takes hours you would otherwise bill or spend on clients, and mistakes with sending setup can hurt your main domain.
Outsourcing means paying an agency to do that work. Our guide to what a cold email agency does lists the pieces, and the cold email agency pricing guide covers what the market charges. You still have to do the selling. An outbound agency starts conversations. Closing them is your job.
A simple way to test the maths: say an average client is worth $2,000 a month to you and stays a year, so $24,000. If outbound costs you $1,400 a month and produces one new client every three months, you have spent $4,200 to win $24,000 of revenue. If it produces nothing in six months, you have spent $8,400 and learned the offer or the audience was wrong. Those are example figures, not a forecast. Put your own into the outbound ROI calculator before you decide.

Frequently asked questions
How do I get my first marketing clients?
Start with people who already know your work: past employers, colleagues, and local business owners you have a connection to. Do a small number of jobs well, ask for introductions, and collect proof you can show the next buyer. Add a second channel before the network runs dry.
How to get clients for digital marketing without a big network?
Pick a narrow niche and go to it directly. Outbound and partnerships do not depend on who you already know. Both work better when you can name the exact type of business you help and the problem you fix for them.
Is cold email worth it for a marketing agency?
It can be, if you have a defined audience, a specific offer, and a client value high enough to cover the cost of starting conversations. It is a poor fit if you sell small one-off jobs or cannot say who your ideal client is.
How long does it take to get marketing clients from outbound?
It depends on your sales cycle. Setup comes first, then replies, then calls, then proposals. With Next Reply a campaign goes live in 14 days. How fast a reply becomes a signed client depends on your offer and how you sell, and no one can promise a number.
Which channel should an agency start with?
Keep asking for referrals, because they cost almost nothing. Then add the one channel you can run every week without fail. For owners short on time, that is often outsourced outbound. For owners who like to write, it may be content.
