INTEGRATIONS · HUBSPOT · OAUTH

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, Job Triggers, and Auto Follow-Up are live immediately.

The HubSpot quick-setup wizard: everything pre-matched from your real HubSpot data, with the deal's job-address property being confirmed against live field samples — Step 2 of 3, on a real connection — your own deal fields, with live samples like “3130 River Valley Dr”, confirmed before anything runs.

WHAT FLOWS BOTH WAYS

Deep, not decorative. Four things run on the connection.

Part of Mailr’s 59 native trigger events across 12 CRMs — with revenue synced back so the attribution dashboard can put a dollar figure on every campaign.

Trigger events

Fire mail off real HubSpot activity, filtered by custom fields — “only deals over $15k in the Roofing pipeline.”

Reactivation

Mailr imports your past deals and contacts from HubSpot, then mails the nearest neighbors of every closed job — your deal history becomes a mailing list you already own.

Lead delivery

Landing-page leads are created as HubSpot contacts at capture time — source-labeled “Mailr”, deduped by email, auto-retried on failure. Every lead deep-links straight to the contact record.

Auto suppression

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 webhooks where HubSpot supports them, plus an hourly sweep, deduped — nothing missed, nothing doubled. Every event takes custom-field filters like “only deals over $15k in the Roofing pipeline.”

Contact created→ campaign fired

Deal created→ campaign fired

Deal stage changed→ campaign fired

Deal closed won→ campaign fired

Deal closed lost→ campaign fired

+ custom-field filters on every event

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, 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.
Can I filter triggers by pipeline or deal size?: Yes — trigger events take 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 supports instant webhooks, so most events fire within seconds. An hourly sweep backstops everything, deduped — nothing missed, nothing doubled.
