Does this work with sub-accounts?

Yes — Mailr installs per location, so each sub-account connects to its own Mailr workspace with its own pipelines, tags, and custom fields.

Can a tag fire a campaign?

Yes — “Contact tag added” is a native trigger, so tagging a contact “mail-neighbors” in HighLevel can drop a campaign on their street. Stage changes, wins, and new contacts fire too.

What does Mailr write back into HighLevel?

Captured leads, as contacts with the “Mailr” source and tag, deduped by email. Everything else is read-only: opportunities and contacts power triggers, Reactivation, and revenue attribution.

Direct mail on autopilot for GoHighLevel.

Install Mailr from the HighLevel marketplace and it goes to work: opportunities moving through your pipeline fire postcards into the right neighborhoods within seconds, landing-page leads land in HighLevel as contacts, and won opportunities stop that home getting mail.

HOW IT CONNECTS

Three steps, and the first one’s the hardest.

01
Connect
An OAuth popup — pick the HighLevel location, approve access, and you're connected. No keys to find.
02
Confirm
A 3-step confirm-only wizard shows real field samples from your own GoHighLevel account — you see your actual data before anything runs.
03
Run
Reactivation, automations, and Auto Follow-Up are live immediately.

The Connect HighLevel dialog in the Mailr app, opened from the HighLevel tile on the connect hub — Step 1 — an OAuth popup, nothing to paste.

The HighLevel quick-setup wizard, step 2 of 3: where the job address lives in HighLevel, confirmed before anything runs — Step 2 — the job address, read straight from HighLevel’s own records and confirmed before anything runs.

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.

Trigger events

Fire mail off real GoHighLevel activity — 5 native events, each filtered by custom fields: “only opportunities over $15k in the Roofing pipeline.”

Reactivation

Mailr imports your won opportunities from HighLevel — by pipeline and stage, won or still open — then mails the nearest neighbors of every one. Your pipeline history becomes a mailing list you already own.

Lead delivery

Landing-page leads are upserted as HighLevel contacts at capture time — source “Mailr”, tagged, your custom fields filled, deduped by email. Every lead deep-links straight to the contact in HighLevel.

Auto suppression

The moment an opportunity is won in HighLevel, that customer is removed from future mailing audiences. You never pay to advertise to someone you already closed.
