Email and direct mail can both play a part in a marketing plan. The useful question is which reaches your audience at a cost your business can justify.
Email is quick to send. A physical note can be kept or shared. Compare the channels on replies, appointments or purchases, using the same measurement period.
This guide covers the research, costs and practical differences to consider before testing the channels together.
What to compare
Industry averages need context. The ANA’s 2023 Response Rate Report is a published benchmark source, but the full findings require a login. Do not assume figures from different reports describe comparable campaigns.
For each channel, record the number of people reached, qualified responses, purchases and total cost. Keep the definition of a response the same.
Choose a channel based on the cost of reaching your audience and the value of the resulting business. Higher response rates alone do not establish better ROI.
Why test physical mail?
A physical note gives you a different way to reach someone. These are reasons to test it, not a promise that it will outperform email:
1. Physical Mail Has Less Competition
Mail and email arrive in different contexts. Do not compare a workplace email count with a household mail count as if they measure the same audience or attention. Further reading: Lob.
2. A Physical Message Has a Different Format
In USPS and Temple University research, physical advertisements left stronger memories than digital ads. The study does not establish an open rate for handwritten cards.
3. A note can be kept
A card can stay on a desk or a shelf after it has been read. You still need a relevant message and a reason for the recipient to reply.
For a sales mailing, write to a defined group and make the next step clear. Count qualified replies and appointments before increasing your spend.
ROI Breakdown: The Real Cost of Each Channel
Email can have a low marginal delivery cost, while physical mail adds production and postage. Build both budgets at the same audience size and include software, creative work, preparation and any offer cost.
But ROI isn't about cost — it's about return relative to cost. And here's where the math gets interesting:
Email Marketing ROI
Email revenue per dollar of spend: use the source’s exact definition and survey population. Revenue/spend is not profit-based ROI. Further reading: litmus.com reference.
Best for: nurture sequences, newsletters, transactional messages, re-engagement
Works at scale with minimal incremental cost
Weakness: declining open rates, spam filters, inbox fatigue
Direct Mail ROI
Calculate your return from the sales you can attribute to the campaign, after subtracting the mailing and fulfillment costs.
Best for: high-value prospecting, account-based marketing, customer retention, win-back campaigns
Higher cost per piece, but higher conversion value
Weakness: slower delivery, higher upfront investment, harder to A/B test at scale
A larger deal value can justify a higher acquisition cost, but it does not make every mailing profitable. Work out how many incremental sales you need to cover the cost before sending.
When to Use Email Marketing
Email isn't going anywhere — and it shouldn't. It's the backbone of most marketing stacks for good reason:
Lead nurturing: Automated drip sequences that educate prospects over weeks or months
Transactional communication: Order confirmations, shipping updates, account notifications
Content distribution: Newsletters, blog roundups, product updates
Re-engagement: Win-back sequences for dormant contacts
Scale: When you need to reach 50,000+ contacts affordably
Email excels at maintaining relationships at scale. It's fast to deploy, easy to automate, and the data feedback loop (opens, clicks, conversions) is immediate.
When to Use Direct Mail
Direct mail shines in scenarios where standing out matters more than reaching everyone:
Account-based marketing (ABM): Targeting high-value accounts with personalized outreach
Sales prospecting: Breaking through to decision-makers who ignore emails
Customer retention: Thank-you notes, anniversary cards, loyalty touchpoints
Event invitations: A physical invitation is an option when the event and recipient justify production and postal lead time; measure registrations instead of assuming an attendance lift
Win-back campaigns: Re-engaging lapsed customers who've unsubscribed from email
A handwritten service can prepare cards for a business mailing. The trigger, wording and audience still need review, and automation does not establish that the mailing will earn a return. Further reading: handwritten card services.
The Multichannel Advantage: Using Both Together
Here's the real answer to "direct mail vs email marketing": don't choose. The data overwhelmingly supports using both.
Combining channels is a testable choice, not a guaranteed 118% lift. Hold other activity comparable and measure what adding mail changes. A general publisher homepage does not establish that percentage. Further reading: Merkle. Further reading: lettrlabs.com reference.
Here is an illustrative sequence to adapt and test, allowing for actual production and postal estimates:
Day 1: Send a handwritten note introducing yourself and your value proposition
After the estimated arrival window: send a relevant email mentioning that you sent a card, without claiming it was received
Later, if appropriate: connect on LinkedIn with a brief message
For a subsequent follow-up: share a useful case study or resource if it is relevant
For a final planned contact: call if appropriate, respect a request to stop, and do not assume the person saw earlier messages
This approach works because it leverages the mere exposure effect: people develop preferences for things they encounter repeatedly. Direct mail creates the initial memorable touchpoint, and digital channels reinforce it.
Use a campaign plan that explains the role of each channel. Do not assume an extra contact automatically increases spending; account for cost and overlapping attribution. Further reading: Lob.
Cost Comparison: Real Numbers for 2026
Let's get specific about what each channel actually costs to run:
Email Marketing Costs
Platform fees: obtain a current quote for the list size, features and sending volume you need.
Delivery cost per email: distinguish the marginal send cost from the full campaign cost.
Design and copywriting: include staff time or a current outside quote.
Total for a 1,000-person email campaign: add the actual software, creative and preparation costs. No universal total applies.
Direct Mail Costs
Printed postcards and letters: request a quote for the format, quantity and preparation required.
Handwritten cards: see current credit prices. One standard card credit includes the card, handwritten message, addressed envelope and US postage.
Postage: as checked September 16, 2026, USPS lists $0.82 for a standard one-ounce letter stamp and $0.65 for a standard postcard. Other sizes, shapes and commercial services have different rates. Do not add postage twice when it is included in a card price. USPS First-Class Mail prices.
Total for a 1,000-person physical mailing: combine current production, preparation and postage quotes. For Scribble, compare the credit purchase needed with the number of cards you will use.
Compare total cost per qualified response and per sale. Include preparation time and follow-up costs for both channels. A cheap send can still be expensive if it produces little useful business.
How Handwritten Direct Mail Changes the Equation
Not all direct mail is created equal. A glossy printed postcard and a handwritten note are both "direct mail," but they perform very differently.
A handwritten card lets you make a message personal through the words, the writing and the choice of design. Test the response with your audience instead of assuming a fixed advantage over printed mail.
Modern handwritten card services like Scribble use real pens (not printed fonts that mimic handwriting) to create genuinely handwritten cards at scale. Key features that make this practical for B2B teams:
Real pen-on-paper: 30 current customer-selectable handwriting styles, with a preview of your message
Scalable: From single cards to 10,000+ campaigns
Order status: see card progress and arrival windows. Scribble confirms when a card is mailed; response and conversion measurement belongs in your own CRM or analytics tools.
CRM workflows: documented API and inbound hooks; check named connector availability and review each trigger. No general 1,000-unit minimum
No subscription: Pay only for the cards you send
Handwriting gives you another way to reach someone. Keep your own records of who received a mailing and how they responded, then compare the results with your other outreach.
5 Industries Where a Mailing May Fit
While both channels work across industries, direct mail has a particularly strong edge in these sectors (Postalytics, Modern Postcard):
Real estate: Neighborhood farming with handwritten "just listed" notes outperforms email drips for listing leads
Financial services: match the communication to the client relationship and the firm’s compliance process; do not assume a sector-wide response rate.
SaaS/B2B tech: Account-based marketing with handwritten outreach cuts through crowded inboxes of decision-makers
Healthcare: review privacy and communication requirements before sending patient-related mail. Avoid sensitive details on exposed surfaces.
Luxury goods: check whether the product margin and customer relationship support the cost of a physical mailing.
In each case, compare the cost of a mailing with the value of the relationships you are trying to build. Use actual replies, sales and repeat purchases to decide whether the investment makes sense.
Measuring Success: KPIs for Each Channel
One advantage email has over traditional direct mail is measurability. But that gap is closing fast with tools like QR tracking and personalized landing pages.
For email, distinguish replies, link clicks and purchases. Open counts can include automated loading. Tracking tags identify visits but do not prove causation; test scope and cost also depend on the platform and audience.
For direct mail, campaign URLs, promo codes and response records can help connect activity to a mailing. Matchback analysis identifies recipients who later converted; it does not establish that the mailing caused each conversion. Use a comparison group when estimating incremental impact.
Use consistent outcome definitions and observation windows. Campaign links help identify some activity, while a comparable holdout group can help estimate the effect of adding the mailing. Neither channel has perfect attribution.

The Bottom Line: Which Should You Choose?
If you're looking at the latest direct mail statistics, the answer is clear: both channels have a place in your marketing mix, but they serve different purposes.
Choose email when: You need speed, scale, and affordability. Email is unbeatable for nurture sequences, content distribution, and maintaining relationships with large audiences at minimal cost.
Choose direct mail when: You need to stand out, build trust, and drive high-value conversions. Direct mail is the better choice for ABM, sales prospecting, customer appreciation, and any campaign where the cost per piece is justified by the deal value.
Choose both when you have a clear role for each channel and a budget to test the added contact. Measure the incremental result before making it an ongoing expense.
Give each channel a specific role and decide how you will judge the result before sending. Compare the additional contribution with the added cost before making the sequence routine.
