How Agencies Manage Multiple Client Brands With Separate Sendspark Workspaces

If your agency runs personalized video outreach for five different clients out of one shared login, you are one copy-paste mistake away from sending a competitor's logo to a paying client. That is not a hypothetical — it is the single most common support question Sendspark hears from agencies, and the fix is not "be more careful." It is setting up your account structure correctly from day one.

Why Managing Multiple Client Brands in One Video Tool Gets Messy

Managing several client brands through one video account gets messy because nothing about the underlying tool tells you which client you're working in — until you've already sent the video. Most video platforms are built for one company, one brand, one set of logins. Agencies bolt five, ten, or twenty client identities onto that same structure using folders or naming conventions, and eventually a folder gets mislabeled or a template gets reused for the wrong client.

This isn't a hypothetical edge case for agencies running AI-personalized video outreach on behalf of clients — it's the day-to-day reality of the job. Every new client brand means a new logo, a new color palette, a new voice to clone, and potentially a new domain the videos need to live on. Do that setup by hand inside a single shared account, and every step becomes a place where one client's asset accidentally ends up on another client's video.

The cost isn't just an awkward apology email. Consistent, correctly-branded communication is one of the few things a client can verify with their own eyes on every single touchpoint — and when it slips, it undermines the exact thing you're being paid to manage. A 2019 Lucidpress study of more than 200 organizations found that consistent brand presentation can lift revenue by up to 33%, and separately found that 81% of companies struggle to keep content on-brand as they scale. Video is one of the highest-visibility touchpoints a brand has, which makes it one of the worst places for that kind of slip.

"I like that Sendspark allows real branding not like some of the other video software that still uses their own links."

The structural fix isn't a better naming convention. It's using an account structure that makes cross-client mixing physically impossible instead of just discouraged. That's what Sendspark's workspace model is designed to do, and understanding exactly what is and isn't shared between workspaces is the first decision every agency has to get right.

Workspaces vs. Sub-Accounts: What's Actually Separate in Sendspark

A Sendspark workspace is a completely independent environment with its own brand styles, team members, and video content, and Sendspark's own documentation uses "workspace" and "sub-account" interchangeably to describe the container an agency sets up for each client. Nothing carries over automatically between them — that's the entire point.

Sendspark's help documentation compares a workspace to a Slack workspace: "every workspace is completely independent of another (with unique brand styles, team members, video content, etc.), but it's easy for you to toggle between them." Practically, that means:

• Brand styles are separate. Logo, color palette, and templates set in one workspace have zero effect on any other workspace.
• Team members are separate. You can give a client's own marketing contact access to their workspace without exposing any other client's videos or contacts.
• Video content is separate. Recordings, dynamic backgrounds, and personalized thumbnails created in one workspace never appear in another.
• Switching is fast. Your team toggles between workspaces from the same login — you don't need a separate account per client, just a separate workspace.

The tradeoff is that a new workspace starts as, in Sendspark's own words, "a near-blank slate" — there's no branding carryover from your agency's main account. You'll re-upload the client's logo, set their brand colors, and rebuild folder structures for every new client workspace. That's a deliberate design choice: it guarantees isolation, but it means onboarding a new client brand takes real setup time, not a one-click clone.

Which Plan Tier You Need for Multiple Branded Client Accounts

The plan tier that fits a multi-client agency depends entirely on how many clients need their own custom domain, not just how many videos you send. Custom domains — the feature that removes Sendspark's own URL from a client's shared video links — start on the Growth plan, but Growth is built around a single workspace's domain, not several. Here's how the tiers actually break down for agency use:

The gotcha agencies hit most often: they sign up for Growth expecting it to cover their first three clients, then discover the custom domain only applies to one workspace. If a second client also wants their own branded domain instead of a shared Sendspark link, that requires upgrading to Team or higher, or running the second client on Sendspark's shared domain without white-labeling. Decide this before you sell "fully white-labeled video" to a second client — not after they ask why their video links say sendspark.com.

Seats matter almost as much as domains here. Growth's 3 seats cover an account manager and a couple of client-facing reps, but most agencies run out of seats before they run out of clients — each new team member added beyond the plan's included seat count costs extra per month on every tier. If you're pricing out an agency rollout, check the full breakdown on the Sendspark pricing page before committing a client to a specific plan tier, since seat and dynamic-video-minute costs compound differently than the domain limit does.

How to Set Up a New Client Workspace With Custom Branding

Setting up a new branded client workspace takes five steps: create the workspace, upload the client's brand assets, connect their custom domain, request minute allocation if you're on an Agency-tier account, and confirm the workspace looks correct before handing off access. Budget real time for this — it isn't instant, and skipping steps is exactly how cross-branding mistakes happen.

1. Create the workspace. Click your avatar in the bottom-left corner, select Change Workspace, then Create Workspace. Enter the client's company name and your job title, and confirm.
2. Upload brand assets. Add the client's logo and set their brand colors inside the new workspace. Nothing from your agency's main workspace carries over — start from the blank slate deliberately, not by accident.
3. Connect a custom domain (Growth plan and above). Add the client's domain in workspace settings; Sendspark generates the DNS records you'll add on the client's or agency's domain registrar. Propagation typically takes a few minutes.
4. Request minute allocation for Agency-tier workspaces. On Agency plans, a new workspace needs its Workspace ID shared with Sendspark support so they can allocate dynamic video minutes to it — this is a manual step, so request it before the client's launch date, not on it.
5. Confirm before handoff. Send a test video from the new workspace and check the branding, domain, and thumbnail all match the client — before adding the client's own team member as a workspace user.

This kind of per-client setup overhead is exactly why agencies accumulate too many disconnected tools in the first place. Marketers managing multiple accounts already juggle a documented 12 to 31-plus tools to run campaigns and data across clients, according to research cited on HubSpot's agency blog. Every extra login is another place a client brand can leak into the wrong account — which is the strongest argument for keeping video personalization inside one platform's workspace model rather than juggling separate tools per client.

Sendspark's video hosting and custom domain setup is also covered in more DNS-level detail in our guide to using CNAME to white-label videos, and how that compares across platforms in which video platforms offer CNAME.

Common Mistakes Agencies Make When White-Labeling for Multiple Clients

The most common multi-client white-labeling mistakes all trace back to treating workspaces like folders instead of separate environments: assuming branding carries over, under-buying plan tier, sharing one workspace across clients, and forgetting to fully remove Sendspark's own branding per client. Each one is avoidable once you know the workspace model isn't automatic.

Once your workspace structure is right, the actual video workflow doesn't change per client — you still record one video and let AI voice cloning personalize it at scale with dynamic backgrounds showing each prospect's own website. The difference is that every client's videos, branding, and domain now live in a container that can't leak into another client's account by accident.

Frequently Asked Questions

Can one Sendspark account serve multiple client brands?

Yes, through separate workspaces under one login. Each workspace has its own brand styles, team members, and video content, so a single agency account can run several distinct client brands without them mixing — but each workspace needs its own setup.

Does branding carry over when I create a new workspace?

No. A new workspace starts as a blank slate with no logo, colors, or templates carried over from your other workspaces. You'll upload the client's brand assets fresh for every new workspace you create.

How many custom domains does the Growth plan include?

Growth ($99/mo) includes a custom domain for one workspace. If a second client also needs their own white-labeled domain instead of sharing Sendspark's default domain, you'll need to upgrade to Team ($299/mo) or a higher tier that supports multiple workspace domains.

What's the difference between a workspace and a sub-account in Sendspark?

Sendspark's own documentation uses the two terms interchangeably. Both describe the same thing: a fully independent environment agencies create per client, with separate branding, team access, and video content.

Can my client log into their own workspace directly?

Yes. You can add a client's team member as a user inside their specific workspace, giving them visibility into their own videos and branding without any access to your other clients' workspaces.

Is a shared workspace with folders per client a safe alternative to separate workspaces?

Not for branding purposes. Folders help with organization, but they don't create the same isolation as separate workspaces — a shared workspace still shares one set of brand styles and one video library, which is exactly what creates cross-client branding mistakes.

How much does it cost to run multiple white-labeled client brands in Sendspark?

It depends on how many clients need their own custom domain and how many seats your team needs across those accounts. Growth ($99/mo) covers one branded client workspace; agencies with two or more branded domains typically need Team ($299/mo) or higher, since seat count and dynamic video minutes scale with plan tier as well as domain count.
