When you think about modern marketing, letter mail might not be the first thing that comes to mind—but it should be. In an era of constant digital noise, lettermail cuts through the clutter, delivering personalized messages that people actually open, read, and trust.
Smart businesses across industries are rediscovering the power of letter mail to connect with customers, build loyalty, and drive real-world results.
Let’s explore how your business can leverage lettermail marketing—and why Torpedo is the best partner to make it happen.
What Is Lettermail and Why Does It Still Work?
Letter mail refers to addressed mail under 50g, including letters, statements, invoices, and marketing offers. It’s delivered quickly—often in just a few days—and reaches homes and businesses directly, with a personal touch that digital simply can’t replicate. Unlike email, which can be ignored, filtered, or deleted in seconds, lettermail lands in a customer’s hand, commanding attention and building trust.
How Different Industries Can Win With Letter Mail
1. Financial Services
Banks, credit unions, and insurance companies can use letter mail to send personalized account updates, rate changes, renewal reminders, or exclusive offers. Customers are more likely to engage with physical communications when trust is key.
Example: A Toronto-based credit union increased customer retention by 15% after mailing tailored mortgage renewal packages to members.
2. Healthcare Providers
Private clinics, dental offices, and pharmacies can use letter mail for appointment reminders, seasonal health tips, or personalized thank-you notes—boosting client relationships and reducing no-shows.
Tip: Adding the patient’s name and appointment date directly into the letter increases open and read rates dramatically.
3. Retail & eCommerce
Whether you’re brick-and-mortar or digital-first, letter mail is an ideal way to promote new collections, offer VIP discounts, or re-engage lapsed customers with a personal touch.
Example: An online clothing brand ran a reactivation campaign by sending handwritten-style promo letters to inactive customers, resulting in a 7% conversion rate—far above their email average.
4. Education & Nonprofits
Universities, training institutes, and charities can use letter mail for fundraising appeals, event invitations, alumni outreach, or donor engagement. Physical letters often yield better emotional response and stronger action from recipients.
5. Professional Services
Law firms, real estate agencies, consultants, and accountants can use letter mail to communicate milestones, policy updates, or important notices in a formal and professional format.
