Direct mail on autopilot for HubSpot.
Connect HubSpot with an OAuth popup and Mailr goes to work: deal-stage changes fire postcards into the right neighborhoods, landing-page leads write back as HubSpot contacts in real time, and closed-won customers stop getting mail automatically.

HOW IT CONNECTS
Three steps, and the first one’s the hardest.
01
Connect
An OAuth popup — approve access in HubSpot and you're connected. No private apps to build, no keys to find.
02
Confirm
A 3-step confirm-only wizard shows real field samples from your own HubSpot account — you see your actual data before anything runs.
03
Run
Reactivation, automations, and Auto Follow-Up are live immediately.


WHAT FLOWS BOTH WAYS
Deep, not decorative. Four things run on the connection.
Part of Mailr’s 63 native trigger events across 12 CRMs — with revenue synced back so the attribution dashboard can put a dollar figure on every campaign.
Fire mail off real HubSpot activity — 5 native events, each filtered by custom fields: “only deals over $15k in the Roofing pipeline.”
Mailr imports your past deals and contacts from HubSpot — filtered by pipeline and stage, or since a date — then mails the nearest neighbors of every closed job. Your deal history becomes a mailing list you already own.
Landing-page leads are created as HubSpot contacts at capture time — source-labeled “Mailr”, deduped by email, auto-retried on failure. Every lead and deal deep-links straight to the HubSpot record.
The moment a deal hits Closed Won in HubSpot, that customer is removed from future mailing audiences. You never pay to advertise to someone you already closed.

HUBSPOT TRIGGER EVENTS
Mail that fires itself off HubSpot activity.
Instant — HubSpot app webhooks fire within seconds, and an hourly sweep backstops everything, deduped. Nothing missed, nothing doubled. Every event takes custom-field filters like “only deals over $15k in the Roofing pipeline.”

QUESTIONS
The questions HubSpot shops ask.
- Which HubSpot plan do I need?
- Any tier with contacts and deals — including the free CRM. The integration uses standard HubSpot objects and connects over OAuth from the Mailr app listing, so there's nothing to install.
- What does Mailr read and write in HubSpot?
- It reads contacts and deals to power triggers, Reactivation, and revenue attribution. It writes new contacts for captured leads, source-labeled “Mailr” and deduped by email. Nothing else in your portal is touched, and disconnecting uninstalls the app on HubSpot's side too.
- Can I filter triggers by pipeline or deal size?
- Yes — every trigger takes a pipeline and stage plus custom-field filters, so a campaign can fire on “Closed Won, Roofing pipeline, over $15k” and ignore everything else.
- How fast do triggers fire?
- HubSpot pushes webhooks to Mailr, so most events fire within seconds. An hourly sweep backstops everything, deduped — nothing missed, nothing doubled.
