The Benefits of Tabbing for Folded Self-Mailers

What Is Tabbing and Why Is It Required?

Tabbing is the process of sealing a folded self-mailer (FSM) using USPS-approved adhesive tabs to keep the piece closed during transit. It’s required for many direct mail formats to qualify for automation discounts and avoid damage during processing.

If you’re mailing brochures, postcards, or newsletters without envelopes, you’ll likely need tabs, and proper placement matters.

• Folded self-mailers include any piece that’s folded but not enclosed in an envelope.

Why USPS Requires It:

• Prevents open flaps from jamming sorting machines
• Ensures the deliverability of folded pieces
• Protects address areas, barcodes, and calls-to-action

Benefits of Tabbed Folded Self-Mailers

Here’s why tabbing is essential—not just for compliance, but for performance:

• Improved Mailpiece Integrity:

• Tabs keep pieces closed and clean
• Prevent premature opening or edge tearing
• Ideal for folded pieces with inserts or multiple panels

• Elevated Brand Presentation:

• Tabs preserve layout and design through transit
• Prevent content misalignment
• Choose clear or branded tabs to align with your style

• USPS Automation Savings:

• USPS offers better postage rates on properly tabbed FSMs
• Speeds up sorting and delivery
• Ensures your campaign qualifies for discounts

Tabbing Placement & Design Best Practices

Designing with USPS rules in mind helps avoid delays or additional fees.

Pro Tip: Avoid glue dots and staples. Only USPS-approved wafer seals are accepted for automation mail.
