Radius Mail lets you automatically send direct mail to households near a specific address — without needing a full mailing list. Anchor a mailer around a "pin address" (a job you just finished, a listing you just posted, a store location) and LettrLabs finds and mails the surrounding homes for you.

Radius Mail is available two ways: as its own standalone order type, and as an action inside automations (for example, triggering a Radius Mail send automatically when a CRM records a completed job). This guide covers the standalone flow; see the Setup Guide for your specific CRM integration (in the Integrations collection) for how to trigger it automatically.

From your LettrLabs dashboard, go to Radius Mail and click New Radius Mail. This page also shows any Radius Mail orders you've created before.

Select a pre-made template — handwritten or printed — you want to use for this campaign.

Add the address you want to be the center of your radius — a job site, a listing, a store location. You can:

Each pin address triggers its own radius of nearby homes.

Narrow your target audience with any combination of:

Filters can improve targeting precision, but they can also push recipients further from the immediate neighborhood. If your message depends on hyper-local proximity ("we just worked next door"), consider leaving filters off so you get the closest possible homes.

In the Service Area section, you'll see each pin address you added and can set the number of recipients per pin.

Unverified: the exact current minimum/maximum recipients-per-pin. Two different pieces of legacy documentation disagreed here (one said a 100-recipient minimum with no maximum, another said "25 or more, adjustable") — confirm the actual current bound on the live order screen before relying on a specific number.

Give your order a name, confirm the card quantity and pricing, then click Checkout. Radius Mail orders ship via first-class postage. You'll get an email confirmation once your order enters production, and a second email once every piece has been mailed.

You can view any submitted order from the Orders tab — click View Details to see the order and its recipient list.

Rather than creating a Radius Mail order by hand every time, you can trigger it automatically from a CRM event — for example, mailing the neighbors around a job the moment it's marked complete in your field-service software. See the Setup Guide for your specific integration in the Integrations collection (ServiceTitan, AccuLynx, Salesforce, Zapier, and others are all live today) for how to wire this up.
