Best Outbound Agencies for Co-Packers and Contract Manufacturers (2026)

Picture a co-packer in the Midwest. Two lines, SQF certified, good at hot-fill beverages. The owner tells me the same story I've heard many times: the line runs full from March to August, then sits at half capacity through the winter, and every new brand they've won came from a trade show or from a broker who happened to know someone.

Then the inbound. A brand with 300 Instagram followers wants 500 units of a "functional soda" and a formula. A national brand wants a quote, then goes quiet for a year because it's locked into a contract somewhere else. Neither fills the line.

The brands that would fill it exist. They're doing $3M to $15M online, they launched four new flavors last year, and their current maker just told them the next run is in April. They just don't know your plant exists.

This guide compares 8 outbound agencies that co-packers, co-manufacturers and private label makers hire to find those brands. How we built it: I'm Rodrigo, co-founder of Romar AI. We run cold email for B2B companies that sell to ecommerce brands, including co-packers, so we put ourselves on the list, and first. Every fact about another provider comes from its own website, checked on October 19, 2026. Where a site didn't say something, I say that.

Top 8 outbound agencies for co-packers in 2026

What does outbound for a co-packer include?

Six pieces of work, and the first two decide whether the rest is worth doing:

• Fit screening. Matching brands to your minimum run, your formats (cans, pouches, capsules, bottles) and your certifications. A brand that needs 500 units is a waste of everyone's time if your floor is 5,000.
• Timing signals. New SKUs in the last year, a store locator that's growing, a move into retail, imported finished goods that just got more expensive. Onboarding a new maker often takes 8 to 16 weeks, so the brand has to start talking before it's desperate.
• Contacts. The founder at smaller brands. VP operations, supply chain or head of product at bigger ones.
• Sending setup. Separate domains and warmed mailboxes so your main domain and your quotes inbox stay clean.
• Copy. One reason to talk, in plain words: a second line for the next SKU, a minimum that fits, US production closer to the warehouse.
• Replies. Fast answers and a hand-off that includes what the brand makes and in what volume.

One market fact I always put in front of co-packers: in Oregon's co-packing study, 86% of co-packers had spare capacity, yet high minimums and fees kept small brands out. The capacity and the demand are both there. The two sides just aren't finding each other, which is exactly the gap outbound fixes.

1. Romar AI: Best for co-packers selling to growing ecommerce brands

Romar AI runs cold email outbound for B2B companies that sell to ecommerce brands, and co-packers, co-manufacturers and private label makers are one of the groups we write for. We find brands launching new SKUs or outgrowing their maker, keep only the ones that fit your minimums and certifications, and get them to reply. We work with companies in the US, Canada, Mexico and the UK, and we're an Instantly Solutions Partner.

Romar AI key services

1. Map. We pull brands in your categories whose label claims and SKU growth match your certifications and run sizes, and drop the ones too small for your minimum.
2. Pick. Together we choose the segments where your offer is strongest and who to write to at each brand size.
3. Reach. Short emails about the one problem you solve, sent from dedicated inboxes at low volume per inbox.
4. Hand off. Interested brands go to your team in Slack or your CRM with the thread and context. We run the cold email.

The segments we usually start with: CPG brands in food, beverage, supplements, beauty and pet at $1M to $20M, apparel and home brands looking at US or nearshore production, and DTC brands entering retail. The signals: new SKUs in the last 12 months, certification claims on the label (organic, gluten-free, GMP, SQF), a store locator, imported finished goods.

Romar AI pricing

Start with a trial, then a retainer priced on the call. We pay for the data and the sending stack, so you don't buy seats, credits or inboxes.

Where Romar AI shines

• Deep qualification. Every brand is checked against your line before an email goes out. Category, run size, certification claims, sales channel. If a brand says "organic" on the label and you're not certified organic, it never hears from you. I've seen makers spend a quarter talking to brands they could never legally produce for, and it's a miserable way to learn.
• We work on the offer. "We have capacity" isn't an offer. "Keep your current maker, use us for the next launch" is. So is stating your minimum in the first email. Most of the time we're reshaping what you already do into a first run that's small enough to say yes to.
• Segments by product category and buyer. A hot-fill beverage brand and a gummy supplement brand don't get the same email. The founder of a $2M brand doesn't get the email the VP of supply chain at a $15M brand gets.
• Copy that reads like a person. Short, plain, about one thing, with two or three versions of each paragraph so no two brands get the same email. Facts and numbers stay fixed.
• Published ecommerce results. Our public cases are with 3PLs selling to ecommerce brands, which is the closest thing to a co-packer's sale we've published. A new 3PL branch of a multinational had 6 qualified meetings and 1 closed deal in its first three weeks. A multi-warehouse 3PL in Houston had its first qualified meeting within 48 hours across 5 verticals.

Where Romar AI falls short

• No published co-packer case study yet. The method is the same, but judge us on the trial.
• Cold email first. No cold calling or LinkedIn. If your buyers live on the phone, CallingAgency or SalesHive fit better.
• Ecommerce brands only. If you want to sell to retailers, foodservice or industrial buyers, look at MarketJoy, Factur or SalesHive.
• Two co-founders run every account, so we take a limited number of clients.

Who Romar AI is best for

Co-packers, co-manufacturers and private label makers in food, beverage, supplements, beauty, pet, apparel or home who want brands at the right size, asking about capacity.

2. Feed The Line: Best for small food, beverage and supplement co-packers

Feed The Line works only with food, beverage and supplement co-packers in the US or UK with roughly 10 to 100 people. That's narrow, and on purpose.

Key services

• Cold outbound to brands, screened by an MOQ fit check (4 to 200 times your per-SKU minimum, per the site).
• One co-packer per category per region, so it isn't pitching your competitor the same brands.
• First sends around day 14, with meetings from weeks 3 to 8.

Pricing

$1,500 a month flat on its launch tier (it calls the first clients the "founding five"), with a 90-day initial term, then monthly. The site guarantees 12 qualified meetings in 90 days or it keeps working free.

Where Feed The Line shines

• A specialist with a public, flat price. Hard to find in this niche.
• The category and region exclusivity is a real protection for small plants.

Where Feed The Line falls short

• It's new enough that the price is a launch tier, so expect it to change.
• Delivery runs from India and the company is run by the directors of DESENO Media Agency, per its site. Fine for many, worth knowing if you want US-hours coverage.

Who Feed The Line is best for

Small and mid-size food, beverage and supplement co-packers in the US or UK that want a specialist and a guarantee.

3. NutriB2B: Best for supplement manufacturers and CDMOs

NutriB2B does buyer acquisition for supplement manufacturers, CDMOs and private label makers, and says it only works in nutrition, beauty, food, ingredients and packaging.

Key services

• An account map by dosage form (capsules, gummies, powders and so on).
• A production inquiry brief for each interested buyer.

Pricing

Its services page lists guide prices: a one-time setup of $1,500 to $3,000, then $2,000 to $5,000+ a month. Bigger multi-product or multi-country programs are custom. It says these aren't a final quote.

Where NutriB2B shines

• Dosage form is how supplement buyers actually think. A gummy brand doesn't care about your capsule line.
• It's clear about limits: it states it doesn't guarantee contracts and doesn't verify GMP status. I like a vendor that says what it won't do.

Where NutriB2B falls short

• Pricing is a range, not a fixed number, and the setup fee comes on top of the monthly.
• No published client results on the pages I checked, and it says plainly it can't promise a number of meetings.
• Supplements and nearby categories only.

Who NutriB2B is best for

Supplement and nutrition makers that want a specialist who speaks dosage forms.

4. CallingAgency: Best for food and beverage makers wanting phone

CallingAgency has a food and beverage page and runs cold calling, email and LinkedIn. It targets retail buyers, distributor procurement, restaurant sourcing, CPG brands and private label buyers.

Key services

• Cold calling plus email and LinkedIn, run on its C.A.L.L.S. framework.
• Emails under 125 words with 3 to 5 variants, per the site.
• Exclusive opportunities, with the first appointment typically in week one.

Pricing

Not published.

Where CallingAgency shines

• Phone is part of the program, which helps for buyers who don't live in their inbox.
• It claims an average of 48+ meetings a quarter.

Where CallingAgency falls short

• No public price.
• Its target list spans retailers, distributors and restaurants, so make sure your campaign is pointed at brands if that's what you want.

Who CallingAgency is best for

Food and beverage makers that want calls in the mix and several buyer types.

5. SalesHive: Best for makers that want US SDRs on the phone

SalesHive's food and beverage page lists co-manufacturing and co-packing sourcing managers among the roles it reaches, alongside grocery buyers and distributor purchasing.

Key services

• US-based SDRs on phone and email, with offshore calling also available from the Philippines.
• List building, email outreach and appointment setting.

Pricing

Month to month. No price on the page I checked.

Where SalesHive shines

• Real food and beverage history: the page reports 11 F&B client accounts and 678 meetings booked since 2021.
• Month to month, so no long lock-in.

Where SalesHive falls short

• Its F&B work leans toward getting brands in front of buyers, which is a different sale from a co-packer finding brands. Ask which direction your campaign runs.
• No public price on the page.

Who SalesHive is best for

Co-packers that want a phone-led SDR team and month-to-month terms.

6. MarketJoy: Best for contract manufacturers outside food

MarketJoy has a page for contract and custom manufacturing: machining, fabrication, electronics manufacturing (EMS) and private label.

Key services

• Email, phone and LinkedIn outreach.
• Qualification on capability, volume, certifications, timing and authority.

Pricing

Not published on its page.

Where MarketJoy shines

• Its qualification list (capability, volume, certifications) is the right one for contract manufacturing.
• Covers hard goods and electronics, which most CPG specialists don't.

Where MarketJoy falls short

• Not focused on CPG or ecommerce brands.
• No public price.

Who MarketJoy is best for

Contract and custom manufacturers selling to OEMs and product companies outside food.

7. Outbound Pharma: Best for pharma CDMOs

Outbound Pharma works in life sciences and publishes a CDMO case study with unusual detail.

Key services

• Account-based outbound for CDMOs and life science service companies.

Pricing

Not published.

Where Outbound Pharma shines

• The CDMO case covers a Canadian CDMO over 12 weeks: 92 campaigns, 350+ companies, 160 engagements, 21 interested and 7 qualified meetings. Real numbers, including the modest ones. I trust that more than a round "300% growth".

Where Outbound Pharma falls short

• Pharma, not consumer brands. A beverage co-packer won't benefit from its specialty.

Who Outbound Pharma is best for

Pharma and nutraceutical CDMOs selling to drug developers.

8. Factur: Best for industrial contract manufacturers

Factur sells appointment setting only to manufacturing companies: contract manufacturers, machine shops, fabricators and similar.

Key services

• Appointment setting with industrial buyers.

Pricing

Not published. The site says volume depends on the market.

Where Factur shines

• Manufacturing-only focus.

Where Factur falls short

• Little public detail on method or results on the page I checked.
• Industrial buyers, not consumer brands.

Who Factur is best for

Machine shops, fabricators and industrial contract manufacturers.

How to choose an outbound agency for a co-packer

1. Ask how they handle your minimum

This is the whole game. If the provider can't tell you how it screens out brands below your run size, you'll get meetings with brands that want 500 units. Feed The Line and Romar AI both screen on it. Ask everyone else.

2. Ask what certifications they match on

If you're SQF or organic certified, brands that claim those on their labels are the easy first segment. If you aren't, those brands should be excluded. A good provider asks for your certificate list on day one.

3. Ask which direction the campaign runs

Several food and beverage agencies are built to get brands into retailers and distributors. You need the opposite: brands looking for a maker. Ask to see 20 sample targets.

4. Ask what you're offering

"We have capacity" gets ignored. A second line for the next SKU, your minimum stated plainly, or US production closer to their 3PL gets replies. Ask them to write the first email before you sign.

5. Ask how long until a brand can start

Onboarding takes 8 to 16 weeks. Your outreach should land before a brand's current maker lets it down, not after.

How much does outbound cost for a co-packer in 2026?

Most providers here quote after a call. That's normal in a niche this small, if a little annoying.

So, which outbound agency is right for your plant?

If your best customers would be growing ecommerce brands and you want them screened against your minimums and certifications, Romar AI is built for that. If you're a small food or supplement plant and want a flat price and a guarantee, Feed The Line is worth a call. Supplement makers who think in dosage forms should talk to NutriB2B. If you want phones ringing, look at CallingAgency or SalesHive. Outside food, MarketJoy and Factur are the better fits, and Outbound Pharma for CDMOs.

If you want to see how many brands fit your line, book a call with Romar AI. We'll build your brand map and show you the first segments we'd test.
