Each mail type serves a specific purpose, from quick attention-grabbing postcards to detailed letters that convey a professional message. Understanding these options will help you select the right format for your campaign goals. --- #### **Direct mail types and how to use them** ### **1. Postcards** - **4x6 Postcards** – Compact and cost-effective, ideal for short, clear messages or promotions. - **6x9 Postcards** – Slightly larger for more design space while still keeping costs low. - **6x11 Postcards** – Provides room for additional content, images, or calls-to-action. *Best Use:* Quick updates, promotional offers, or announcements that need to stand out in a mailbox. --- ### **2. Personal Letters** - **Personal Letters** (**8.5x5.5)** – Handwritten-style letters that feel personal and direct. *Best Use:* Motivated seller outreach, relationship-building messages, or when a personal touch is key. --- ### **3. Professional Letters** - **Windowed Envelope** (**11x8.5)** – Standard business letters that display recipient addresses through the envelope window. - **Non-Windowed Envelope** (**11x8.5)** – Professional letters with fully printed envelopes for a polished look. *Best Use:* Formal communications, official notices, or business correspondence requiring a professional appearance. --- ### **4. Real Penned Letters** - **Real Penned Letters (8.5x5.5)** – Letters that mimic actual handwriting, making your mail feel personal and authentic. *Best Use:* High-response campaigns where personalization and trust are critical. --- ### **5. Snap Pack Mailers** - **Snap Pack Mailers** (**11x8.5)**– Folded mailers that snap open, creating a high-engagement experience. *Best Use:* Promotional materials, property investment offers, or campaigns that require a visual “wow” factor. --- ### **6. Self-Mailers** - **Bi-Fold Self-Mailers (6x18)** – Folded brochures that stay folded for easy mailing. - **Tri-Fold Self-Mailers (12x9)** – Larger, multi-section mailers for detailed content or multi-step offers. *Best Use:* Informative campaigns, multi-step offers, or content-heavy promotions. --- #### **Tips for choosing the right mail type** 1. **Match the format to your message length:** Short messages → postcards; longer messages → letters or self-mailers. 2. **Consider your audience:** Personal letters or real penned letters work best for high-touch outreach. 3. **Engagement factor:** Snap packs and bi/tri-fold mailers can grab attention and increase response rates. 4. **Budget:** Postcards are typically the most cost-effective; letters and custom mailers may cost more. --- Selecting the right mail type in Invelo ensures your message is delivered effectively and resonates with your audience. Properly matching your mail format to your campaign goal can improve engagement and response rates. - [Getting Started](https://helpdesk.inveloapp.com/getting-started?hsLang=en#main-content) - [Welcome Series](https://helpdesk.inveloapp.com/getting-started?hsLang=en#welcome-series) -
