We make marketing sends look seamless and easy

Behind every beautiful campaign is a whole lot of receiving, sorting, quality control, assembly, recycling, coordination, packaging, and shipping. Lucky for you, that’s our thing.

We help marketing agencies with:

Inventory receiving and organization

Kit assembly and hand-packing

Product arrangement and presentation

Custom inserts, collateral, and printed materials

Bulk sends to events, influencers, media, retailers, or client teams

Re-kits, refreshes, and staggered campaign waves

Amazon FBA prep when needed

Basically: if your agency dreamed it up, we can probably kit it, pack it, and ship it.

Let's get started

For agencies running sends like…

Influencer seeding programs

Need to ship curated mailers to 50, 500, or 5,000 creators? We’ll receive the inventory, build the kits, and get every send out the door with the kind of polish that earns actual unboxing content.

Product launches

Launching something new? We help agencies build product launch kits that feel on-brand, intentional, and ready for their close-up.

Sample sends

From trial-size products to branded sample packs, we make sure the packaging, presentation, and fulfillment feel as thoughtful as the campaign itself.

PR and media kits

Editors, creators, partners, internal stakeholders — whatever the audience, we help your kits land with impact instead of chaos.

Corporate and client gifting

Have the products already? Amazing. We’ll turn them into a high-touch gifting experience your client will absolutely want to do again.

Why marketing agencies choose Sidekick

We’re good at the tricky stuff

Complex pack-outs? Multiple vendors? Tiny components? Last-minute inserts? Weird shapes? Split shipments? Honestly, custom isn’t a thing we do- it’s the only thing we do

We care how it looks

We came from the world of premium gifting, so we know presentation isn’t extra — it’s the point.

We move fast

We can typically start kitting within 1–2 business days of receiving inventory, which is part of why agencies use us when timelines are tight.

We don’t act like robots

You get real humans, real communication, and a team that actually answers emails before your blood pressure rises.

We flex with your projects

One launch. One campaign. Ongoing sends. A one-off test run before moving more volume. We’re into all of it.
WE’RE JUST A HOP, SKIP, AND A KICK AWAY

The Sidekick difference

not assembly lines in their conference room

A lot of 3PLs can ship boxes.

Not a lot of 3PLs can help a marketing agency execute a send that needs to be:

  • On-brand
  • Presentation-forward
  • Hyper-customized
  • Deadline-sensitive
  • Multi-component
  • Client-ready
  • Creator-worthy
  • Actually fun to open

Or throw up the bat signal. Same thing.

The reviews are in:

“Working with Sidekick Kitting literally changed the trajectory of my business. Before I found them, I had said no to opportunities with large retailers because I knew I wasn't set up to deliver successfully.

Partnering with Sidekick not only meant they could handle the volume of those orders, but they had the expertise to navigate the detailed (and complex) requirements of shipping to major retailers. They have prepared multiple orders for us, each with thousands of units. Torrance & her team communicated early & often and I knew I was in good hands.

As a seasonal wholesale business, our orders come sporadically. I don't have the ability to hire and maintain operational staff year round. Rather than recruiting and training temporary employees and trusting they'll get it right, partnering with Sidekick has allowed me to focus on growing the sales of my business while trusting they will deliver for me operationally. They can flex to whatever my volume needs are. It's been a game changer and I can't recommend them enough!”
