Turnaround Time

• Production Time: 1-2 business days after order confirmation.

• Mail Class: USPS First Class (ensures timely delivery).

Best Practices for Product Selection:

• Postcards: Use 4x6 for reminders or discount offers. Upgrade to 6x9 for visual-heavy campaigns or to stand out.

• Letters: Ideal for personal or high-value outreach—especially when more context is needed (probate, high-ticket sales).

• Snap Packs: Perfect for urgent-looking communications like tax notices or special event invitations.

• Self-Mailers: Great for educational campaigns or multi-offer promos. Use tri-folds for content-rich mailers.

• Real Penned Letters: Use for relationship-driven outreach or when targeting limited high-value prospects.
