You've planned your routes, designed your postcard, and executed your Every Door Direct Mail campaign. Now comes the most important question: Did it work?
Measuring ROI ensures your marketing dollars are well spent and helps you refine future campaigns for even better results. Most small businesses skip this step entirely, which means they have no idea whether their next campaign should be bigger, smaller, or scrapped.
In this guide, we'll explain how to measure EDDM ROI, what tools to use, and how to get better results from every campaign after this one.

Why Tracking ROI Matters
Many businesses skip this step and simply hope their mailers work. But without tracking:
- You don't know which campaigns brought real customers
- You can't compare EDDM performance to digital marketing
- You may waste money repeating ineffective strategies
With the right tracking system, you'll know which offers, routes, and designs deliver the best return.
Step 1: Define ROI for Your Campaign
ROI is the money earned compared to money spent.
Formula: ROI = (Revenue Generated - Campaign Cost) / Campaign Cost x 100
Example:
- Campaign Cost = $1,200
- Revenue Generated = $4,800
- ROI = (4,800 - 1,200) / 1,200 x 100 = 300%
Tip: Even if your first campaign breaks even, the long-term brand exposure often pays off in repeat business.
Step 2: Track Responses Effectively
There are multiple ways to track how customers respond to your mailer:
Unique Promo Codes
Include a code like "MAIL20" or "EDDM10" that can only be redeemed from that campaign.
Call Tracking Numbers
Use a unique phone number that forwards to your main line. Services like CallRail let you track which campaign generated the call.
Landing Pages and QR Codes
Send recipients to a dedicated page, such as yourwebsite.com/offer. Add a QR code for mobile-friendly access.
In-Store Tracking
Train staff to ask, "How did you hear about us?" and log responses.
Step 3: Compare Costs vs. Returns
Break your analysis into three parts:
- Cost per Piece Delivered: printing plus postage plus design, divided by total pieces
- Response Rate: responses divided by pieces delivered, multiplied by 100
- Revenue per Response: total revenue divided by total responses
Example:
- 2,500 postcards mailed, total cost approximately $1,000
- 75 responses (3% response rate)
- Average sale $80 = $6,000 revenue
- ROI = (6,000 - 1,000) / 1,000 = 500%

Step 4: Evaluate Campaign Effectiveness
Ask yourself:
- Did you reach the goal you set before the campaign?
- Which offer drove the most responses?
- Were some routes more effective than others?
- Did your timing align with customer demand?
Document results in a simple spreadsheet so you can compare across campaigns.
Step 5: Improve Future Campaigns
Once you have results, refine your approach:
- Test Offers: Try different discounts, bundles, or time-limited deals
- Adjust Routes: Focus on the neighborhoods that responded best
- Improve Design: Highlight your CTA more clearly or simplify text
- Combine Channels: Pair EDDM with Google Ads or Facebook retargeting for multichannel impact
Tip: Businesses often see better ROI after their second or third campaign, as they fine-tune routes and offers.
Common Mistakes to Avoid
- Not tracking responses at all
- Using the same generic offer for every campaign
- Ignoring timing and seasonality
- Dropping mail without testing routes
- Expecting instant ROI without accounting for brand-building effects
