Your list is the asset. Keep it clean.

Import hundreds of thousands of prospects — and for land work, the properties and owners behind them. GoMailOffers dedupes, splits, verifies and suppresses on every upload, so the list you mail is the list you meant.

The data model

Three linked records, not one flat spreadsheet.

Prospects, properties and owners are first-class records that stay linked — so an owner with five parcels is one person, one mailing, one bundled offer code.

Prospects

The people and households you mail. Display IDs like P-1234 make them referenceable in notes, exports and support.

Properties

For land and real-estate work — parcels with APNs, mailing addresses, and county data, each linkable to up to two owners.

Owners

The link between the two. Multi-property owners are detected and merged, so nobody gets five letters with five different codes.

Organize without a CRM

Tags and notes — marketing structure, not pipeline stages.

GoMailOffers is deliberately not a CRM. You get tags for segmenting, notes for context, and filters for targeting a campaign — and your leads flow onward to whatever CRM you already run.

Tag anything. County, list source, season — then target campaigns by tag.
Notes with history. Context stays on the record across every campaign.
Your CRM stays yours. Push captured leads out via webhooks and the API.

Suppression

Opt-outs are forever — and automatic.

When someone asks not to be mailed, that suppression lives on the address and the person — not on one campaign. Re-upload the same list next quarter and they are held back without you remembering anything.

Held at every gate. Suppressed records are excluded at import, targeting, and print.
Carried across uploads. Suppression survives re-imports, renames and new tags.
Auditable. Who was suppressed, when, and which sends honored it — all logged.

List FAQ

Asked by everyone with a messy spreadsheet.

How big can my list be?
The platform is built for hundreds of thousands of records per account and sends of tens of thousands of pieces a day. The Free plan caps records; Pro is unlimited.
What happens when I re-upload an updated CSV?
Records are matched, not duplicated — existing prospects update in place, new rows are added, and suppressions, tags, notes and campaign history all survive the re-import.
Do I need property data to use GoMailOffers?
No. Properties and owners are first-class for land and real-estate verticals, but a plain prospect list — names and mailing addresses — is all any other business needs.
Can I export my data?
Yes — prospects, leads and campaign results export to CSV anytime, and webhooks and the API can stream leads to your own systems continuously. Your list is yours.
