Best marketing automation for agencies, and the client workspace question that two vendors answer and we do not

An agency does not buy marketing automation for the same reason a brand does. A brand buys it to stop doing something by hand. An agency buys it to do that thing for ten clients at once without any of the ten appearing in another one's reports, and that requirement is a different product with a different failure mode.

So the shortlisting question is not which platform has the better workflow builder. It is one row: what does a client account look like inside this product, and who can see it.

The row that sorts the market, and the three answers to it

Separate accounts. Each client gets its own subscription, and you log into ten of them. Cheapest to start, worst to run. Your team loses half an hour a day to switching, and nobody can answer a portfolio question without opening ten tabs.

Sub accounts under one parent. One login, a client list, per client data separation. This is what an agency actually wants and it is usually the most expensive tier of the product, because the vendor knows it.

One account with tags. Everything in one database, clients separated by a label. Works until somebody runs a send without the filter applied, and then it has failed in the one way an agency cannot explain to a client.

Ask every vendor which of those three it sells, in writing, and whether a client user can be given access to only their own records. A vendor that answers the second half slowly is answering it honestly.

The counter, which decides the bill rather than the shortlist

Every product in this category bills on one of three counters and an agency is exposed to all of them at once because it carries ten lists rather than one.

Contacts stored. You pay for every record whether you ever contact it or not. Punishing for an agency inheriting old client lists, and the reason a bill triples after an onboarding import.

Messages sent. You pay for volume. Better for an agency with many small, rarely contacted lists; worse for one client with a daily send.

Seats, workflows or API calls. Common at the top of the market, and the cap that bites an agency is almost never the seat count. It is the number of simultaneously active automations, because ten clients with four sequences each is forty.

Count your real figures before any demo. Total stored records across every client, total monthly sends, number of staff who will log in, and total active sequences. Then ask each vendor for the overage rate in dollars. The overage rate gets the vaguest answer of any question in a sales call and it is the number that decides the annual cost.

For the product side of this purchase rather than the agency side, this site compares what the vendors publish, including HubSpot's own stack naming, at HubSpot marketing automation compared. Measured on 21 October 2026, no other page on this site links to that one, against 2,405 live pages of which 982 carry no inbound internal link on the same measure, 40.8 percent and an upper bound because a link can only be counted in a body we hold.

The measurement an agency's automation stack cannot produce, and who publishes the best answer to it

There is one client question that no automation platform answers, because the data is not in your client's database. The client asks why a competitor keeps getting named when a buyer asks an assistant who to use. Nothing in a sequence builder has ever seen that sentence.

Three vendors publish an agency answer to it and the comparison is a short one, because this is a page about client workspaces and only one of them publishes a workspace figure.

Vendor	What its own page published on 21 October 2026	The agency workspace row
Profound	Free Trial of "50 unique prompts", "Daily for 7 days", 3 answer engines, "Unlimited" seats, SSO "No". Enterprise priced "Custom" with "Up to 9 Answer Engines tracked" and "SSO/SAML + SOC 2 compliance".	Publishes a per client figure. Its FAQ names an Agency Growth plan with "400 credits per month per client workspace", and seats are "Unlimited" on both published tiers.
SE Ranking	"Track brands across Google AIOs, AI Mode, ChatGPT, and Gemini", "5 free checks per day", a 14 day trial with "No credit card required", and "Add up to five competitors".	Publishes client reporting by integration rather than by workspace, naming "Data Studio, AgencyAnalytics, or Whatagraph", and lists Agency Pack and White Label as separate products.
AI Knows Us	Agency at $1,299 a month for 80 buyer questions, 12,300 credits and all five apps. A Claude check uses 3 credits because Claude costs more to run; most checks use one.	Publishes a brand count rather than a workspace, and our own page contradicts itself about it. See below.

Profound beats us on this page's own criterion, and our own pricing page is why

The criterion this page ranks on is the client workspace, and Profound is first on it by name. It publishes a per client credit allowance and unlimited seats, which is the shape an agency needs: a workspace per client and a whole team able to open them. We publish one login with full access on every plan, which means an agency account manager and an agency analyst share the same seat.

Worse for us, and worth putting on the page rather than in a footnote: our own pricing page carries two contradicting readings of whether we support more than one business at all. Read on 21 October 2026, the Agency plan is described as covering 10 client brands, while the comparison table's "More than one business" row reads "No" for every plan, Agency included. Both render. We are reporting both rather than choosing the one that flatters us, and an agency should get that row confirmed in writing before buying on it.

Where AI Knows Us is nonetheless the right line on an agency's software budget is narrower than a shortlist position. It is the one deliverable an agency can take into a client meeting that the client cannot get from its own stack and cannot check against the agency's own reporting, because the question is asked with the client's name left out of it. Three named competitors get returned when a buyer asks an assistant who to use, the client does not, and the publishing work that changes that is specific and schedulable. Our Agency tier prices that at a published figure, in six currencies, which is more than Profound publishes for its agency plan and less flexibility than its workspaces give.

Questions agencies ask before buying automation

Can we resell the platform under our own brand? Some vendors permit it on their top tier and most do not. We do not: white label does not render anywhere in our pricing text, and anyone who greps our page and finds the string SSO in a script payload should know it renders nowhere on the page.

Who owns the client's data when the client leaves us? Settle it in the client contract before the platform contract. The platform will answer that the account owner owns it, which moves the question rather than answering it.

Is a cheap tool with tags ever acceptable for ten clients? For ten clients with small lists and no overlapping audiences, it survives. It fails the first time a filter is forgotten, and that failure is visible to the client rather than to you.

Do we need a separate tool for answer engine measurement? Today, yes, because no automation platform reads those surfaces. Whether that stays true for another year is a vendor roadmap question and nobody has published a date.

Correction, 21 October 2026

This page stated that no other page on this site linked to the page it points at. That was true when it was measured and it stopped being true within the hour, because another page on this site, best email and sms marketing platform compared and the one line that tells you whether sms is actually included, was published linking the same target while this page was going live. The orphan count it quotes, 982 of 2,405 live pages, was also measured before that publishing run; re-measured immediately afterwards it read 1,015 of 2,485, which is 40.8 percent either way. Both figures are left in place with their dates rather than quietly overwritten, because the useful fact here is that the denominator on this site moves by dozens of pages in a single afternoon and any single reading of it is a snapshot.
