Support coverageAlways-on help for regulated postal workflows.
01 — The problem
Your documents are digital. Your postal work is still scattered.
Professional teams already run on CRMs, practice management tools, accounting systems, spreadsheets, cloud drives, and design tools. But the moment a document needs to leave the business as physical mail, the workflow breaks. Someone exports a file, copies an address, prints a letter, buys postage, checks tracking, and later tries to prove what happened.
Post office time sink
Your team loses time managing stamps, franking machines, supplies, drop-offs, and label printing.
Verified proof gets separated
The letter, address, quote, tracking, and verified proof often live in different places.
Campaigns are hard to repeat
Marketing teams need bulk mail that connects to contacts, creative assets, and customer history.
02 — The solution
The all-in-one postal office inside your office.
PostBridge connects the document workflow to the postal workflow. Send a letter, import contacts, print stamps, buy labels, run bulk mail, or connect an API without sending your team to the post office.
Mail letters
Upload a PDF, create a letter, confirm the recipient, review the quote, and send after approval.
Import contacts
Pull recipients from tools like Google Sheets, Clio, QuickBooks, Salesforce, HubSpot, and more.
Print stamps and labels
US teams can print USPS stamps, plus USPS and FedEx shipping labels from the app.
Run bulk campaigns
Send customer letters, postcards, and direct mail campaigns without rebuilding your list by hand.

06 — Use cases
Built for teams and industries that still need postal document outflow.

Send statements, payment reminders, account notices, invoices, and regulated correspondence without leaving your digital workflow.

Direct mail campaigns connected to your CRM and creative tools.

Use PostBridge for win-back campaigns, VIP notes, renewal reminders, local promotions, appointment prompts, and customer appreciation mail. The goal is not more paper. The goal is meaningful customer contact that your team can measure and repeat.
