HubSpot Marketing Hub is CRM-first marketing automation. SuprSend is agentic, multi-channel orchestration for every message your product sends, run by teams and agents together.
Trusted infrastructure layer behind hundreds of platforms
HubSpot Marketing Hub and SuprSend both send campaigns, journeys and triggered messages to people. HubSpot does it from the CRM, for a marketing team working on contacts in its UI. SuprSend is agentic, multi-channel orchestration for the users of a product: engineers, product, growth and agents all work on the same workflows, and every kind of message runs through them.
The SuprSend agent in the dashboard or Slack builds workflows, writes copy per channel and traces failed sends. Over MCP, Claude, ChatGPT or Cursor create users, write templates, run a broadcast and read the delivery log. HubSpot’s agents work inside its UI, and its MCP drafts emails without sending them.
Email, SMS, WhatsApp, mobile push, web push, Slack, Teams, an in-app inbox and webhooks sit on one user profile, on every plan. A password reset and a win-back campaign share the same workflows, preferences and logs. HubSpot is email-first: SMS is an add-on and push needs marketplace apps.
Each tenant is isolated, with its own sending domain and provider, its own version of every template, its own channel and category defaults, and a per-tenant feed, nesting five levels deep. Each user sets preferences per channel, category and digest schedule. HubSpot has brands and subscription types per channel.
Workflows batch and digest on the user’s schedule, hold sends to the recipient’s timezone, route across channels until the user responds, and fall over to a backup provider. Every workflow and template keeps versions with rollback, and test mode blocks real delivery. HubSpot has revision history and no provider failover.
A product manager changes a workflow in the dashboard. A developer ships the same workflow as a file in a pull request. A marketer asks Claude to write this week’s campaign and send it to a list. All three work on the same workflows, templates and logs, so nobody waits on a ticket.
The built-in agent builds, edits and debugs notifications from a description; product and growth ship without a ticket.
Connect the MCP to Claude, ChatGPT or any client and run templates, workflows, tenants and preferences from there.
The CLI and API keep workflows versioned, diffable and reviewed in pull requests; coding agents make bulk changes.
One SuprSend customer runs its marketing email end to end from Claude Code, with nobody in the dashboard.
HubSpot is built and changed in its own UI: the workflow canvas, the email editor and Breeze Assistant. Its remote MCP server lets Claude or ChatGPT read CRM data and create email drafts, campaigns and static segments; it cannot build a workflow or send an email. Workflows can be created over the automation API, in beta.
A marketing team working in the SuprSend dashboard also runs the event-driven transactional messages, such as password resets, invoices and alerts, from the same workflows, lists and logs as its campaigns.

HubSpotHubSpot Marketing Hub is marketing automation built on the HubSpot CRM. A contact arrives through a form, is nurtured by email and workflows, scored, and handed to sales, with every step recorded on one contact record.
It suits companies whose marketing and sales share that record. Landing pages, ads, social, SEO and reporting through to revenue sit around the email, so one team can run its whole funnel in one product.
SuprSendSuprSend is agentic, multi-channel orchestration for products. The password reset, the comment mention, the invoice and the win-back campaign run through the same workflows, on every channel, with one set of preferences and logs.
It suits product companies where engineers, product and growth all send messages, often with agents doing part of the work. It connects to a CRM such as HubSpot and logs each message back to it.
HubSpotMarketers build emails, workflows, segments, landing pages and ads in the HubSpot UI, with Breeze Assistant inside the editors. Developers work on the CRM API, the HubSpot CLI for apps and CMS content, and client libraries in Node, PHP, Python and Ruby.
Agents connect to HubSpot’s remote MCP server to read CRM data and email analytics, update records, and create email drafts, campaigns, pages and static segments.
SuprSendEngineers integrate once through the API, a backend SDK in Python, Node, Java or Go, the CLI and MCP, and keep workflows and templates in the repo. Product and growth build workflows, lists, content and broadcasts in the dashboard, or have the built-in agent build them, with versions to roll back.
Agents connect over MCP from Claude, ChatGPT, Claude Code or Cursor and create users and lists, write templates, trigger a notification, run a broadcast and read the log.
From both pricing pages, HubSpot’s product and services catalog and both documentation sites, September 2026. Plan names mark the lowest plan that includes a feature.
Everything in SuprSend has an API and a file form behind the dashboard, so an agent or a script can change it. HubSpot’s marketing tools are built for a person in its editors; its APIs and MCP reach CRM records and email drafts, and creating workflows by API is in beta.

Most teams move the messages their product sends and keep HubSpot as the CRM. Users, lists and templates move directly; workflows are rebuilt.
| HubSpot | SuprSend | Moves how |
|---|---|---|
| Contact | User | Users API, SDK or CSV, keyed by your user ID |
| Contact properties | User properties | Sent as JSON; no fields to create |
| Active segment | Dynamic list | Rebuild the rule, or a warehouse query |
| Static segment | List | CSV export, then import |
| Marketing email | Email template with versions | Paste the HTML; rebuild tokens as variables |
| Workflow | Workflow | Rebuild; no export maps across |
| Subscription types | Preference categories | Map each type to a category |
| Unsubscribes | Opt-outs | Export and import before the first send |
| Brands | Tenants | Tenant API; then domain, logo, defaults |
| Email activity | Logs | Stays in HubSpot; new sends log back by webhook |
Inventory HubSpot workflows and emails, and mark which are product messages and which stay in HubSpot.
Stand up SuprSend development and staging. Connect email and SMS providers with a fallback order, and create tenants if you have customer accounts.
Import users by your own ID, their properties and opt-outs; map subscription types to categories.
Rebuild the critical flows first, such as onboarding, billing and security alerts, and test them in test mode.
Add a webhook step that logs each send to the HubSpot contact, so sales keeps the full history.
Run both in parallel for a week, then move the remaining flows and switch off the HubSpot versions.
Enterprise customers get migration support and a scoped plan; on other plans the Slack community and docs are the path.
SuprSendSuprSend is better when your messages start from your product and have to reach users on several channels, with transactional, product and marketing messages in one system that engineers, growth and agents all work in.
HubSpotHubSpot is better when marketing runs on the CRM with sales: landing pages, forms, ads, lead scoring and revenue attribution on the same contact record.
Yes. Many teams keep HubSpot for sales and marketing records and send product, transactional and lifecycle messages from SuprSend. A webhook step in the SuprSend workflow logs each message to the HubSpot contact, so sales sees the full history.
Yes. SuprSend builds lists from rules, warehouse SQL, CSV or CDP sync and runs one-time, scheduled or recurring broadcasts on any channel, through the same workflows, preferences and logs as its transactional messages. HubSpot goes further on landing pages, A/B testing and revenue attribution.
SuprSendSuprSend stores preferences per category: the user picks channels, a digest schedule and conditions, and a tenant admin can set the defaults above them.
HubSpotHubSpot stores subscription types per channel on the contact, with a hosted preferences page for email, SMS and WhatsApp.
SuprSendSuprSend runs in SuprSend cloud on every plan, and in your VPC, on-prem or as BYOC on Enterprise, with the full product and support.
