EDDM Planner is a free planning tool from 9x12tools, operated by Seek First Development LLC. It helps you choose postal routes, estimate costs, share coverage, and prepare mailing documents.
Free planning access
Route exploration and estimates are available without an account. A verified email is required to save plans, publish coverage, and create documents. Accounts can save up to 100 plans. There is no planner subscription or credit card requirement. Printing, postage, and any optional 9x12tools subscription are separate.
Check before you mail
Route data and delivery counts can change. Cost results are estimates based on the displayed postal rate and your inputs. You are responsible for your final quantities, printer specifications, postal eligibility, forms, and payments. Confirm your mailing with USPS before printing or presenting it for acceptance. Generated paperwork does not purchase postage or submit a USPS order.
Your campaign
You control the information you enter and whether you publish a coverage link. Only publish information you have permission to share. A break-even calculation is arithmetic using your inputs, not a promise of sales, income, delivery outcomes, or advertiser results.
Website access and third-party information
We do not offer a public API, bulk data feed, or license to redistribute third-party route or map data. The planner’s internal interfaces support the website only and are not supported integrations. Public informational pages may be read and linked to by search engines and AI assistants. Third-party information remains subject to its providers’ rights and applicable terms; this website does not grant additional rights to it.
Reasonable use
Do not attempt to access another person’s private plans, bypass rate limits, disrupt the service, or use the public interfaces for bulk scraping. We may restrict abusive access to keep the tool available.
Availability and support
The service is provided as available. Data sources and features may change, and interruptions can occur. EDDM Planner is independent and is not affiliated with or endorsed by USPS. Questions or problems: hello@9x12tools.com.
