MailXstream integrates with your existing workflow by supporting a variety of document processing formats. Your team can upload files exactly as they are generated by your internal billing or invoicing systems, ensuring zero manual reformatting:
- Single PDF, Single Document: Upload one file addressed to a single recipient, a standard layout supported across all of our submission channels.
- Single PDF, Bulk Documents: Submit a single master file containing statements for multiple different addresses. Our platform automatically handles the data parsing, splitting the master PDF into separate mail pieces.

Soft Inserts
The MailXstream Soft-Inserts feature seamlessly adds newsletters, marketing collateral, and company announcements directly into your outbound delivery envelopes alongside monthly statements or invoices. This eliminates the need for separate marketing deployments or printing excess copies in-house.
By bundling these targeted updates with your primary billing documents, you ensure customers receive vital information instantly while maximizing communication efficiency and avoiding additional postage costs. To learn even more about soft inserts, check out this resource.
Cover Page
Our intelligent Cover Page feature resolves common document formatting and address alignment issues by providing automated layout fixes without altering your original files. If your address block does not match standard window envelope templates and cannot be repositioned, our team will design a compliant cover sheet to serve as the first page of your mailing.
This custom order template allows you to seamlessly automate your print-to-mail workflow while maintaining complete document integrity, requiring zero programming or costly layout redesigns. To learn even more about our cover pages feature, click here.
Householding
With rising postal rates, mailing multiple separate envelopes to the same recipient is an unnecessary operational expense that drains your budget and impacts customer satisfaction.
MailXstream’s automated householding feature resolves this issue by scanning your data streams to combine separate documents bound for the same delivery address or parent-child account relationships, even if they originate from entirely different production batches. By merging these individual statements into a single outbound mail piece with an envelope size determined by your total page count, you achieve substantial postage savings and eliminate excess material waste while projecting a highly professional brand image.

Online Tracking
MailXstream provides complete transparency across your print-to-mail pipeline with comprehensive real-time tracking from initial data upload to official handoff at the USPS.
All critical order details and tracking metrics are securely maintained within our online document archive for 90 days, enabling easy internal audits and seamless reporting. Following successful distribution, users can readily retrieve an official MailXstream Certificate of Mailing that documents the exact time and location each mail piece entered the postal network to guarantee absolute regulatory compliance.
