Most postal service businesses rely on word-of-mouth and walk-in traffic, leaving significant revenue on the table. Your competitors are already using email to win corporate shipping contracts, announce new services, and fill idle retail hours. The right email strategy can turn occasional customers into recurring revenue streams and help you compete with national carriers.
Why Email Works for Postal Services
Email reaches business decision-makers directly—the purchasing managers, office managers, and small business owners who choose where to send packages. Unlike social media, email stays in inboxes and isn't buried by algorithms. A well-timed message about bulk shipping discounts or new notary services can land a contract worth thousands annually.
The postal industry benefits uniquely from email because your customer base is habitual: they mail regularly, they have budgets, and they respond to convenience-based offers. Your existing customer data is one of your most valuable assets.
Building Your Email List
Start with customers you already have. Collect email addresses at the counter by offering a small incentive—10% off their next purchase, priority handling coupons, or a guide to mailing regulations. Most postal operations collect addresses during transactions; organize and segment this data by customer type (residential, small business, corporate).
For new B2B leads, partner with local business groups, chambers of commerce, or commercial real estate networks. Buying a cold list is risky and usually ineffective; growth through warm outreach and existing relationships works better in this sector.
Aim to build a list of 500–2,000 qualified business contacts within your first six months. Quality beats quantity—100 active business accounts matter more than 5,000 inactive email addresses.
Email Segments That Drive Revenue
Corporate and bulk shippers Send these contacts quarterly reports on your shipping volumes, rate changes, and new services. Monthly offers on flat-rate boxes, priority handling, or volume discounts keep you top-of-mind.
Small business owners Target local retailers, e-commerce sellers, and service providers with semi-monthly tips: optimal packaging to reduce damage claims, postage cost comparisons, and seasonal shipping surge preparation. These contacts typically mail 20–100 packages monthly and respond well to educational content mixed with offers.
Occasional residential customers Email them seasonal reminders (holiday shipping deadlines, tax document mailing windows) and new retail services (passport photos, mailbox rentals, UPS drop-off availability).
Content That Converts
Keep emails short. Postal customers want answers fast—don't write paragraphs when a bulleted list works.
High-performing email topics:
- Rate changes and deadline announcements (compliance-driven, gets opened)
- Holiday shipping cutoff dates (time-sensitive, action-oriented)
- New services or extended hours (solves a customer pain point)
- Bulk discount eligibility and package deal offers (direct ROI conversation)
- Regulatory updates (passport renewals, business documentation requirements)
- Local event sponsorships or community news (builds local brand loyalty)
Subject lines matter. Test "Extended Weekend Hours Starting Next Month" against "Are You Open Saturdays?" The first is specific and news-driven.
Timing and Frequency
Send emails Tuesday through Thursday, 10 a.m. to 2 p.m. Avoid Mondays (overloaded inboxes) and Fridays (people checking out). Most postal service businesses see best results with one email every 10–14 days for active subscribers.
Pre-holiday seasons (October for holiday shipping, March for tax deadlines) warrant weekly outreach. Off-season may drop to bi-weekly.
Measuring Success
Track open rates (aim for 25–35% for this sector), click-through rates (3–8% is solid), and conversions (did they buy flat-rate boxes, rent a mailbox, request a price quote?).
If an email doesn't hit 15% opens after two sends, refresh the subject line or segment. If a service offer converts consistently, build it into your next campaign.
Getting Found and Growing
Beyond email, list your services on platforms like Mercoly to get discovered by businesses actively seeking postal solutions, win qualified leads, and sell products and services online. This synergizes with your email efforts—you're reaching customers through multiple channels.
Frequently Asked Questions
Q: How often should I email my customer list? Send once every 10–14 days for best results; too frequent causes unsubscribes, too infrequent means customers forget your services.
Q: What's a realistic open rate for postal service emails? Aim for 25–35% opens; business-focused emails about services and offers typically perform better than promotional-only blasts.
Q: Should I segment residential and business customers differently? Yes—business customers respond to cost and compliance messaging, while residential customers engage more with convenience and seasonal reminders.
