The short answers, grouped by topic. Each one links to the page with the full detail. If you don’t find what you need here, contact support.

​
Getting started

Yes. The website field is required because Mailr reads your site to build your brand kit — logo, colors, company details, and photos of your work — while you finish setting up. If your site is thin, you can add or correct everything by hand afterwards in the brand kit.
Creating the workspace is instant. Reading your website takes a minute or two, and collecting showcase photos and reviews can run for several minutes more. You can keep working while it happens — pages fill in on their own. See set up your workspace.
Click your workspace name in the bottom-left of the sidebar, choose Manage organization, and invite them by email. Owners can do everything including buying credits and connecting a CRM, Staff can build campaigns and designs, and Members can only view. Full breakdown: team and roles.
Both are owner-only actions. You’ll see a message saying only your organization’s owner can purchase credits or connect a CRM — ask them to do it, or contact support. More on what each role can do: team and roles.
Yes. New accounts get a small allowance of free preview renders, and the campaign wizard offers a Free preview run: enter an address you know and Mailr renders real cards for it and its closest neighbors. Nothing mails and no money moves. See create a campaign.

​
Campaigns and mail

Go to Campaigns → New campaign and work through four steps: pick a campaign type, choose who to mail, choose your postcard settings, then review and submit. Step-by-step: create a campaign.
Not as a recipient list. You can upload past job addresses to mail around, and addresses to suppress, but Mailr’s targeting is geographic and property-based rather than list-based. See targeting.
From property records for the area you selected, limited to homes with street-level photo coverage. There is no demographic or consumer-data targeting. See targeting.
The map count is taken before your exclusions run. Only homes with street-level photo coverage can be mailed, your Who to mail setting removes recent customers and recently mailed homes, and property filters narrow it further. The Review step shows the real number and how many homes were excluded. See targeting.
No. Submitted means the campaign is with Mailr for review. Credits are held, not charged, and you can still use Withdraw submission to pull it back to draft. Every status explained: statuses and timelines.
Once a campaign reaches Printing it is typically in the mail within about two business days; delivery time after that depends on the postal service. Scheduled follow-up drops mail on their drop date. See statuses and timelines.
While it says Draft, delete it. While it says Submitted, use Withdraw submission on the campaign page — the credit hold is released. Once it is in production or printing the mailing is committed, so contact support. See campaign troubleshooting.
Every postcard’s landing page carries a do-not-mail link. Confirming there removes that address from your mailing list and from every other business that mails through Mailr, immediately and for future mailings. See opt-outs and suppression.
Yes — Assets → Suppression list → Add address, category Do Not Contact. Do Not Contact addresses are never mailed, even by a campaign set to send to everyone. See opt-outs and suppression.
No. Mailr mails within the United States only. See campaigns overview.

​
Designs

On a Home Render card the front is personalized — each recipient sees their own home, re-rendered in the style you choose. On a Classic card the front is identical for everyone and only the QR code varies per household. Both are 6 × 9 in. See designs overview.
A stand-in. Previews in the studio, the library, and the approval proof all show a sample home because there is no recipient in context — each recipient’s printed card features their own house. See property imagery.
No. Mailr’s personalization is visual rather than mail-merge text: what varies per card is the home image on the front, the unique QR code, and the mailing address block added in production. Your company name, phone, website, logo, and colors come from your brand kit. See personalization.
You do. You review the proof of both sides, tick the four confirmation boxes, and approve. There is no separate Mailr design sign-off afterwards — an approved design is immediately usable in campaigns, and approving locks that version. See create a design.
Not every property can be used: open land and homes with no usable imagery are dropped, so mail volume can come in slightly under target in rural or newly built areas. You are never charged for a card that wasn’t produced. If you need guaranteed volume, use Classic postcards. See property imagery.
Every card is 6 × 9 in, front and back. Uploaded artwork must be a PNG at exactly 2775 × 1875 px, up to 15 MB, with text kept at least ¼ in in from every edge and the bottom-right postal area of the back left clear. See upload your own.

​
Integrations

Mailr has native connections for a broad set of home-services CRMs, plus CallRail for call tracking. Anything else — including ServiceTitan — connects through the Mailr app for Zapier with the same triggers, lead sync, and revenue tracking. If your software has no Zapier connector, a developer can connect it directly with the Mailr Developer API. See integrations overview, Zapier, and Custom integration.
No. The first sync starts the clock at the moment you connect, so jobs and deals that closed before then never trigger a campaign. To test it, close a fresh record after connecting. See integrations overview.
Some CRMs send events instantly; others are checked hourly, so a campaign can be queued up to an hour after the event. Either way the campaign goes to Mailr for review before anything mails. The per-CRM cadence is shown in the app and in integrations overview.
No. You can draw neighborhoods on a map or upload past job addresses instead. A CRM connection is what makes campaigns fire automatically and lets Mailr track deals and revenue back to your mail. See automations.
Yes — choose Your own landing page in the campaign wizard and paste your URL. Scans are still tracked per household, and an optional snippet shows each scanner a rendering of their own home on your page. See embed widget.

​
Tracking and results

Their scan is recorded and they land on the page you chose for that campaign, personalized to their address: a rendering of their own home, their street address pre-filled in the form, and your logo, colors, and reviews. See landing pages.
Direct results came through the landing-page form (or a call to a tracking number on the card). Indirect results are address matches — a new customer showed up in your CRM at a home you mailed, without ever scanning. Combined is both together. See attribution.
When a deal is marked won in your CRM, Mailr matches the job’s address back to the household you mailed, inside the attribution window you chose when you set up the connection (30, 60, 90, 180, or 365 days). If you mailed the same address more than once, the most recent mailing gets the credit. See attribution.
Those numbers come from a connected CRM. Without one you still get QR scans and landing-page leads, but deals and revenue stay at zero. See dashboard.
No — treat it as estimated spend. It is calculated at a flat per-card rate for a quick read on performance, while your real charges follow your graduated pricing. Check Billing → Transaction History for what you were actually charged, or see payments and invoices.

​
Billing and credits

Receipts for each credit purchase are emailed when the payment settles, and Billing → Transaction History is the full record of every charge. If you have a monthly subscription, Manage subscription opens a billing portal with downloadable invoices. Credit-only accounts have no in-app invoice list yet — use the emailed receipts, or email support@getmailr.com for copies. See payments and invoices.
No. Credits are held when you submit and charged when your cards are produced. Cards that can’t be produced are refunded to your balance automatically, and withdrawing or rejecting a campaign releases the hold. See credits and pricing.
No, it’s graduated rather than retroactive: the first cards of the month are priced in the first volume band, the next ones in the next band, and so on. Volume resets each calendar month and counts both card types together. Your live rates and your current band are always shown on the Billing page. See credits and pricing.
Printing, postage, and delivery. See credits and pricing.
Credits expire 12 months after purchase and are always spent oldest-first; you get a warning email before the first expiry. There is no auto-reload — topping up is always a deliberate action. See credits and pricing.
Mailing credits pay for postcards — printing, postage, and delivery. AI design credits are a separate balance used when you generate or edit a design in the studio. Both are shown on the Billing page. See credits and pricing.
The campaign stays a Draft and the review step shows the shortfall with an Add credits button — nothing is charged and nothing is submitted. Automation-created campaigns wait as drafts too and submit themselves once you top up. See credits and pricing.
Cards that are never produced, or that are scrubbed as undeliverable, are refunded to your credit balance automatically and appear in Transaction History as Refunded. Once the postal service accepts a mail piece, postal delays or loss are not refundable. See refunds.
