    Automated Mail Assembly

    Inserting Services

    Complex Packages. Assembled Automatically.

    High-speed automated insertion of letters, flyers, and reply cards into envelopes — accurately and at scale.

    What Is Inserting Services?

    Inserting equipment takes stacks of pre-printed components — letters, brochures, BREs, reply cards, coupons — and automatically collates and stuffs them into envelopes in the correct sequence. The result is a ready-to-mail package assembled accurately at high speed, without manual labor and with built-in verification for each component.

    Inserting is the process of placing one or more printed components into an outer envelope automatically using inserting equipment. Catdi Printing's inserters handle everything from simple #10 letter packages to complex multi-component packages with reply cards, brochures, and BREs — at thousands of pieces per hour.

    Frequently Asked Questions

    Our inserters accommodate up to 6 individual components per envelope depending on thickness. Total package thickness cannot exceed the maximum for your envelope size. Contact us with your component specs for a feasibility review.
    Yes, within limits. Z-folds, C-folds, and accordion-folded pieces are compatible with most inserters. Very thick or irregularly shaped items may require hand-inserting for a portion of the run.
    Piece verification uses sensors or cameras to confirm each required component is present before the envelope is sealed. If a component is missing, the envelope is diverted for inspection. This protects you from compliance issues and incomplete packages reaching recipients.
    Automated inserting is cost-effective starting around 500 pieces. For smaller quantities, hand-inserting may be more economical. We'll recommend the right approach based on your volume and complexity.
    Yes. We stock standard #10 envelopes and can source custom sizes, window configurations, and security-tint liners. Provide your specs and we'll include envelope cost in your quote.
