How to Do Bulk Mailing
Posted on March 20, 2026So you’ve weighed the pros and cons of bulk mailing, examined how it can work for your business, and scrutinized the costs of bulk mailing postage. If you’ve made it this far, you must be ready for the nitty-gritty:
How to send bulk mail.
Here’s a helpful guide we’ve put together based on our experience helping 129,865 mail over 1 billion postcards:
Step 1: Define Your Target Audience
Before you print anything, answer this:
Who is most likely to buy from you?
You can mail to:
- Your existing customers (reactivation or upsell)
- A purchased mailing list (targeted by income, home value, age, industry, etc.)
- A geographic area (saturation mail)
Step 2: Choose Your Mail Type
Most businesses use:
- Postcards (fast, visible, affordable)
- Letters in envelopes (more formal, longer message)
- Oversized postcards (stand out more in the mailbox)
Step 3: Ensure your design is eye-catching
If you want your mail piece to stand out in the mailbox, then it needs to have the following elements of a good design:
- One strong headline and a sub-headline
- List of clear benefits
- One main call to action
- Business information, like a phone number or QR code
- Clean layout (not cluttered)
- Colorful eye-catching photos
If they can’t understand who you are and what you are selling in seconds, your mailer is too complicated.
Also make sure you include one or more offers.
Examples:
- Free consultation
- Limited-time discount
- Free gift

Step 4: Print and Prepare Correctly
For bulk rates, the mail must:
- Be formatted to USPS size guidelines
- Have proper addressing
- Include an indicia (bulk postage mark)
- Be sorted and bundled correctly
Mistakes here can cost you money in postage adjustments. While you could do this yourself, it would take a lot of time. Working with a professional mail house like PostcardMania ensures that everything is done according to USPS standards, and you also save yourself time and the headache of the whole process.
Step 6: Mail Consistently
Here’s what most marketers and business owners sending mail in bulk do:
They mail once.
They wait.
They judge the entire strategy off one drop.
That’s not how it works.
Bulk mail success comes from repetition. Familiarity builds trust. Trust drives response.
When we mail at PostcardMania, it’s not about one campaign. It’s about sustained visibility. Consistency beats intensity.
You don’t have to take our word for it just because we mail over 4 million postcards a week. We’ve collected over 1,000 direct mail case studies you can browse to see exactly what worked for other businesses.
Step 7: Track Everything
You must track:
- Calls (use call tracking numbers)
- Website visits (custom landing page or URL)
- Leads
- Sales
- Lifetime value
If you don’t track, you can’t measure ROI. If you can’t measure ROI, you’ll panic too early and quit. With PostcardMania, you have access to an easy-to-use dashboard called MyPostcardMania that shows you exactly when mailers arrived, how many times people scanned your QR code, and how many phone calls came in as a result of your campaign.
What Bulk Mailing Actually Costs
Costs vary by:
- Quantity mailed
- Postcard size
- Postage class
- Targeting data
The more you mail, the lower your cost per piece becomes. So the decision to launch bulk mailing is a no-brainer. You not only save money, but you also create a steady stream of leads for a long period of time.
The Big Picture
Bulk mailing is not about sending a “lot of stuff.” It’s about building a lead engine and trust with the community. When you show the local area you are a credible business that has a lot to offer, you become a presence that can’t be ignored.
