Reselling managed Mautic without becoming a hosting company — what it takes for a small agency in 2026
TL;DR
Mautic is open-source marketing automation under the GPLv3 licence, with around 9,700 GitHub stars and a community-run release cycle. You can resell it to clients as a managed service without running servers yourself.
Mautic has no native multi-tenancy. The safe pattern is one Mautic instance per client, isolated by its own database and container. GitHub issue #2667 has tracked the multi-tenant request since 2016.
At €9 per instance per month wholesale and €30–50 retail, the margin is €21–41 per client per month. Twenty clients is €420–820 in recurring revenue, before your own setup fees.
The HubSpot Solutions Partner Program charges a $400/month membership from 15 July 2026, or asks you to carry $400+/month in HubSpot software. A credible Marketing Hub Professional practice runs about $890/month plus a one-time $3,000 onboarding fee.
DANIAN adds apps to the catalog the same day a partner asks. There is no commission tier yet — that gap is real, and this post is honest about it.
The agency math
Reselling managed Mautic works as a productized recurring line.
You buy each client's instance wholesale and charge a flat monthly fee.
At €9 per instance and €30–50 retail, you keep €21–41 per client per month.
Twenty clients returns €420–820 in monthly recurring revenue, and it recurs without new project work.
Agency operators have a name for revenue like this: mailbox money. It arrives every month without a fresh proposal behind it. The 2024 AgencyAnalytics benchmark report found that 43% of agencies already run on retainers as their primary pricing model. A managed-tool line sits neatly beside those retainers.
The reason to add it is margin stability. Promethean Research put the average digital-agency net margin at 13% in 2025, down from 14% in 2024. Recurring lines lift that number, because they carry almost no delivery cost once they are running. Recurring revenue also raises what an agency is worth if you ever sell it.
The math itself is flat. Each client is one €9 line item on your monthly DANIAN bill. You decide the retail price. Charge €30 and you keep €21; charge €50 and you keep €41. There is no per-seat ladder and no per-contact surcharge waiting to surprise the client at 5,000 contacts.

The multi-tenancy trap (and the clean way around it)
Mautic has no built-in multi-tenancy. Running several clients inside one shared database is the fragile path: contacts, segments, and consent records can collide, and one upgrade can break every client at once. The standard fix is one Mautic instance per client, each isolated by its own database.
This is the question that decides whether reselling Mautic is sane or a support nightmare. Mautic was built as a single-tenant application. The request to add multi-client support has been open on GitHub as issue #2667 since 2016, tagged as a feature for a future release. It is not in core today.
Implementation partners say the same thing in plainer words. Axelerant, a Mautic partner, recommends separate instances per client for security and scalability, and warns against putting multiple clients in one installation. The Mautic architect community frames tenant data leakage as the central risk of any shared-database design.
DANIAN's model maps onto the safe pattern by default. Each app you deploy runs in its own isolated container with its own database. One Mautic equals one client. An upgrade or a misfire touches that client and no other. You get the isolation Mautic itself does not provide, without building or maintaining the orchestration that makes it work.
What white-label actually requires
White-labelling Mautic for clients comes down to three things: a custom domain per client, a branded sign-in, and a billing path that keeps your agency as the vendor of record. None of these requires you to own servers. They require a host that isolates each instance and lets you point your own domain at it.
Start with the domain. Each client's Mautic should live on a subdomain you control, such as mktg.clientname.com. The tracking pixel and the click-redirects then resolve to that domain, so a client's contacts only ever see the client's brand. First-party tracking also survives browser privacy changes better than third-party pixels.
Next, the sign-in. A branded login screen means the client logs into their marketing tool, not into a host's portal. The underlying infrastructure stays invisible, which is exactly what white-label means in practice.
Last, billing. Two clean options work. You can bill the client directly through Stripe, or Stripe Connect, and pay your €9 wholesale cost on the side, keeping the margin visible. Or you fold the cost into a larger monthly retainer as pass-through invoicing, so the client sees a single line. Either way, you stay the vendor of record.
The DANIAN partner setup today (honest about gaps)
DANIAN's partner setup today is deliberately simple: €9 per app per month wholesale, one isolated instance per client, your domain and branding on top, and same-day catalog additions when a partner needs an app we do not yet list. There is no commission tier yet. That is the honest gap.
Here is what exists. Each instance is isolated, so per-client separation is the default rather than something you engineer. Application data sits in the region you choose, across 21 datacenter locations on six continents, so you can place each client near their audience. Support performs DNS edits, SMTP setup, and config tweaks, which removes the work that usually eats an agency's afternoon.
There is also a same-day catalog-add commitment. If a partner needs an open-source app we do not yet list, we add it the same day you ask. That keeps your offer flexible as a client's stack grows.
Here is what does not exist yet. There is no formal commission or referral payout tier, so the margin you earn is the spread between €9 and your retail price, not a kickback. There is no bulk-provisioning partner dashboard yet either. If those gaps matter to your model, say so before you commit.

Three open-source apps that resell well
Mautic is the lead, but two catalog apps pair with it. EspoCRM gives your client a sales pipeline that receives Mautic's qualified leads. n8n glues Mautic to the rest of a client's stack — forms, billing, and CRM sync. Each runs at €9 per instance, isolated, on a domain you control.
Mautic — marketing automation
Mautic is open-source marketing automation under the GPLv3 licence, with roughly 9,700 GitHub stars and a 24-month major-release cycle. It runs the core jobs a client expects: segmentation, email campaigns, landing pages, forms, and lead scoring. It replaces the marketing layer of tools like HubSpot Marketing Hub for clients who want to own their list.
DANIAN runs managed Mautic at €9/month, patched, backed up, and monitored.
EspoCRM — the CRM pairing
EspoCRM is an open-source CRM under the AGPLv3 licence. It holds the sales pipeline — leads, contacts, opportunities, and deals — while Mautic handles the marketing side. The natural flow is marketing-to-sales handoff: Mautic nurtures and scores a contact, then passes the qualified lead to a salesperson working it in the CRM.
You can pair Mautic with EspoCRM so qualified leads land straight in a pipeline.
n8n — the cross-tool glue
n8n is a workflow-automation platform with more than 400 integrations. It can provision onboarding steps, sync Mautic contacts to a CRM or a billing system, and trigger campaigns from external events. One note for resellers: n8n is fair-code under its Sustainable Use Licence, not OSI-approved open source, so check its licence terms before you build a resale offer on it.
DANIAN runs managed n8n at €9/month.
What each path actually costs an agency
Four paths lead to a recurring marketing-automation line: the HubSpot partner route, self-hosting Mautic on a VPS, an existing white-label Mautic build-out, or managed Mautic through DANIAN. The table below sets the commitments side by side. The managed-Mautic path carries no membership fee and no build-out fee.
| Path to reselling marketing automation | Up-front commitment | Recurring cost to you | Per-client isolation |
|---|---|---|---|
| HubSpot Solutions Partner Program | Partner certification + a regional onboarding fee | $400/mo membership from 15 Jul 2026, or $400+/mo HubSpot software; a Marketing Hub Pro practice ≈ $890/mo + $3,000 onboarding | A separate HubSpot portal per client |
| Self-host Mautic on a VPS yourself | 5–10 hours of setup per instance | ≈ $24/mo per production-class VPS, plus backup, monitoring, and your ops time | Yes, with one VPS per client — but you run every upgrade |
| An existing white-label Mautic build-out | A one-time cluster fee (Autoize: $6,300–$9,450, March 2024 pricing) | ≈ $11–14/mo per instance wholesale | Per-client containers |
| Managed Mautic via DANIAN | None | €9/mo per instance | One isolated Mautic instance and database per client |
The HubSpot route is the one pricing small agencies out. From 15 July 2026, every partner pays a $400/month Partner Program Membership, waived only if net HubSpot software spend already exceeds $400/month. A credible Marketing Hub Professional practice carries about $890/month plus a one-time $3,000 onboarding fee. Partners earn a flat 20% revenue share. The older Solutions Provider Program sunsets on 15 August 2026.
Self-hosting on a VPS can pencil out for a single client, at around $24 per month for a production-class server plus backup and monitoring. Across a book of clients, the per-instance patching and the upgrade cycle become real recurring time. An existing white-label build-out removes the sysadmin work but front-loads a large one-time fee; Autoize's last public pricing, from March 2024, was $6,300–$9,450 to stand up a Mautic cluster in your own cloud account. AccuWeb, by contrast, sells generic reseller hosting where Mautic is one install among many, not a Mautic-specific program.
When this works (and when it doesn't)
Reselling managed Mautic fits agencies that already run email or lead-gen for clients and want recurring revenue without servers. It does not fit agencies chasing fully passive income, or those whose clients specifically demand a brand name like HubSpot. The product you sell is your expertise, not the hosting.
Three signals say this is a fit:
You already manage email, funnels, or lead-gen for clients on a retainer, so the strategy work is something you do anyway.
You want recurring revenue that does not grow your headcount with every new client.
Your clients value owning their data and their contact list rather than renting access to it.
Three signals say it is not:
You want hands-off passive income. Deliverability and campaign support still land on you, every month.
Your clients insist on a named brand they already trust, and will not consider an open-source tool.
You have no interest in marketing-automation strategy and only want to resell a server. The margin lives in the strategy, not the hosting.
What you still own (the honest part)
Managed hosting removes the sysadmin layer: patching, backups, monitoring, and uptime. It does not remove the work that makes marketing automation succeed. Email deliverability, campaign setup, and major-version upgrades stay with you. That work is exactly what you are charging the client for.
Deliverability is the big one. Mautic sends through an external SMTP relay that you configure, so sender reputation, DKIM, SPF, and DMARC remain your responsibility. The host keeps the instance online; inbox placement is a discipline, not a setting. Every blacklist event and every spam-folder placement is yours to fix.
Upgrades are the other one. Mautic actively supports its latest version, and major jumps such as 5 to 6 to 7 can change behaviour. A managed host applies the upgrade and holds the backups, so the instance stays current and recoverable. Confirming that each client's campaigns and integrations still fire after the jump is your job, and part of the fee.
Frequently asked questions
Can a small agency resell Mautic without becoming a hosting company?
Yes. You resell managed Mautic the way you resell any tool: the host runs the servers, patching, and backups, and you keep the client relationship. With DANIAN, each client gets an isolated Mautic instance at €9 per month wholesale. You add your strategy and branding on top and bill the client directly.
How much margin can an agency make reselling managed Mautic?
At €9 per instance wholesale and €30–50 retail per client, you keep €21–41 per client every month. Twenty clients returns €420–820 in recurring monthly revenue. The margin holds whether you bill through Stripe or fold the cost into a retainer, and it recurs without new project work.
Does Mautic support multiple clients in one installation?
No. Mautic has no native multi-tenancy. The feature has been an open request on GitHub, issue #2667, since 2016. Running several clients in one installation means sharing one database, which risks contact and segment collisions. The supported pattern is one Mautic instance per client, each with its own database.
What does white-labelling Mautic for clients actually require?
Three things: a custom domain per client, a branded sign-in screen, and a billing path that keeps your agency as the vendor of record. None requires you to own servers. Each client's Mautic runs on a subdomain you control, with tracking and sending on their own domain, so the client never sees the host.
How is this different from the HubSpot Solutions Partner Program?
The HubSpot program is built around selling HubSpot. From 15 July 2026 it charges partners a $400/month membership, or asks you to carry $400+/month in HubSpot software, plus certification and a regional onboarding fee. Reselling managed Mautic has no membership fee: you pay €9 per client instance and keep the client on software they own.
What happens to my clients if I stop working with DANIAN?
Because Mautic is open-source and each instance is isolated, the data is portable. You can export a client's full Mautic database and assets and move the instance elsewhere, or hand it to the client. There is no proprietary lock-in layer between you and the software, which is the point of building on open source.
Is Mautic a good alternative to HubSpot for small agencies in 2026?
For agencies whose clients want owned email and lead nurturing without per-contact pricing, yes. Mautic is open-source under GPLv3 and runs the same core jobs: segmentation, campaigns, forms, and lead scoring. HubSpot wins on polish and brand recognition. Mautic wins on cost and data ownership, especially once a client's list passes a few thousand contacts.
How much does the HubSpot Solutions Partner Program cost in 2026?
From 15 July 2026, every partner pays a $400/month Partner Program Membership, waived only if net HubSpot software spend already exceeds $400/month. A credible Marketing Hub Professional practice runs about $890/month plus a one-time $3,000 onboarding fee. Partners earn a flat 20% revenue share. The Solutions Provider Program sunsets on 15 August 2026.
Is Mautic actually free and open source?
Yes. Mautic is released under the GNU GPL v3 licence and is free to download and self-host. It is community-governed through a Council and working groups, with the trademark held by Open Source Collective. The code has around 9,700 GitHub stars. You pay only for hosting and your own time, never a per-seat or per-contact licence.
How do I bill clients for managed Mautic?
Two clean options. Bill the client directly through Stripe, or Stripe Connect, and pay your €9 wholesale cost separately so the margin stays visible. Or fold the cost into a larger monthly retainer as pass-through invoicing, so the client sees one line. Either way you stay the vendor of record and set the retail price.
Who handles email deliverability when I resell Mautic?
You do, not the host. Mautic sends through an external SMTP relay you configure, so sender reputation, DKIM, SPF, and DMARC stay your responsibility. The managed host keeps the instance patched and online; inbox placement is a campaign discipline. This is part of what you charge the client for, not something hosting removes.
Can I put my own domain and logo on a client's Mautic?
Yes. Each client's Mautic runs on a subdomain you choose, such as mktg.clientname.com, with a branded sign-in. Tracking pixels and email links resolve to that domain, so the client's contacts only ever see their own brand. The underlying host stays invisible. This is the white-label setup most agencies want.
How many clients do I need before reselling Mautic is worth it?
The margin is positive from the first client, since there is no membership fee to amortise. The recurring revenue becomes meaningful around 10–20 clients: at €21–41 margin each, that is roughly €210–820 per month. Start with one client to prove the workflow, then productize the offer across your book.
Should I self-host Mautic on a VPS instead of using a managed host?
You can. A production-class VPS runs about $24 per month, plus backup, monitoring, and your time for patching and upgrades. For one client it can pencil out. Across a book of clients, the per-instance ops time compounds, and every major Mautic upgrade is yours to run. Managed hosting trades that recurring time for a flat €9 fee.
Can I connect Mautic to a CRM for my clients?
Yes. Mautic handles marketing; a CRM handles the sales pipeline. EspoCRM, an open-source CRM under the AGPLv3 licence, receives Mautic's qualified leads so your client's sales team works deals while Mautic nurtures the rest. Both run at €9 per instance on DANIAN, isolated per client, on domains you control.
Can I automate Mautic client onboarding?
Yes, with a workflow tool. n8n, an automation platform with more than 400 integrations, can provision setup steps, sync Mautic contacts to a CRM or billing system, and trigger campaigns from external events. It runs at €9 per instance. Note that n8n is fair-code, not OSI-approved open source, so check its licence for resale terms.
What happens when a major Mautic version upgrade lands?
Mautic actively supports its latest version, and major jumps such as 5 to 6 to 7 can change behaviour. A managed host applies the upgrade and keeps backups, so the instance stays current and recoverable. Verifying that each client's campaigns and integrations still work after the jump is the agency's job, and part of the service you sell.
Is one shared Mautic database safe for multiple clients?
It is the fragile path. A single shared database puts one client's contacts, segments, and consent records beside another's, and one bad upgrade can break every client at once. Mautic implementation partners such as Axelerant recommend separate instances for isolation. DANIAN runs one isolated container and database per client by default.
Do I need to be technical to resell managed Mautic?
You need marketing-automation literacy, not server skills. The host handles deployment, patching, backups, and monitoring. You handle segmentation, campaign building, deliverability hygiene, and the client relationship. If you already run email or lead-gen on a retainer, you have the skills. The hosting layer is exactly the part you pay €9 to not touch.
What does it cost to host Mautic for one client per month?
On DANIAN, €9 per month covers one isolated Mautic instance: one vCPU, RAM, 30 GB storage, 1,000 GB traffic, patching, daily off-site backups, monitoring, and support. Heavier clients can add resources at €9 per extra vCPU/RAM unit. You set the client's retail price on top, commonly €30–50 per month.
What are the risks of reselling Mautic to clients?
Three real ones. Deliverability problems land on you, since you own sender reputation. Clients may prefer a brand name they recognise over an open-source tool. And you become the data controller for client contact data, so consent handling is your responsibility. This is operational guidance, not legal advice; confirm your data obligations for your region.
Conclusion — what to do this week
If you already run marketing for clients, reselling managed Mautic is a recurring-revenue line you can start this week. Pick one client, deploy one isolated Mautic instance at €9, put your domain on it, and price it at €30–50. Prove the margin on one before you productize it across your book.
The case is straightforward. Mautic is real open-source software with a community release cycle behind it, not a vendor you are betting your clients on. The per-client isolation that keeps reselling safe is the default on a managed instance, not something you build. And the cost to start is €9, not a four-figure membership or a five-figure build-out.
What you bring is the part that was always yours: the strategy, the deliverability discipline, and the client relationship. The hosting is the layer you stop thinking about.
