How To Create Bulk Certified Mail - Step by Step Guide.

Print Multiple Certified Mail Labels at Once

Certified Mail batch processing is designed for organizations that routinely send large numbers of important letters, legal notices, compliance communications, collection notices, property notices, and other documents that require proof of USPS acceptance, tracking and proof of delivery events.

With Certified Mail Labels, you can:

Upload hundreds of addresses from Excel or CSV
Create up to 1,000 Certified Mail labels per batch
Import recipient information instead of typing addresses individually
Review and correct mailing data before processing
Print USPS Certified Mail labels from your office
Track every Certified Mail piece individually
Obtain Electronic Delivery Confirmation
Add USPS Return Receipt Electronic when a recipient signature is required
Maintain searchable mailing and delivery records for 10 years
Process additional batches whenever needed
Pay as you mail with no monthly subscription

We currently support CSV, XLS, and XLSX data formats, subject to the required batch-file formatting.

How Does Certified Mail Excel Batch Processing Work?

Creating bulk Certified Mail labels takes five basic steps.

1. Download the Certified Mail Excel Template

Start with the Certified Mail Labels Excel Batch Template. The template provides the proper columns and formatting needed to import your mailing list.

Required address information includes:

Recipient name
Address Line 1
City
State
ZIP Code

Additional fields can be used for other mailing or internal reference information.

2. Add Your Recipient Addresses

Copy or enter your mailing list into the spreadsheet.

Instead of entering each Certified Mail recipient individually through a web form, the spreadsheet lets your organization prepare an entire mailing list at once.

This is especially valuable when mailing:

Legal notices
Collection letters
Tax notices
Property management notices
HOA and condominium notices
Government correspondence
Regulatory notices
Insurance communications
Healthcare notices
Employee and HR notices
Default or delinquency notices

Before uploading a large mailing, review your data carefully for missing or incorrectly formatted addresses.

3. Upload Your Excel or CSV File

Address Letters → Excel Batch Label Processing

Choose the mailing options for your batch, including your return address, USPS mailing service, envelope type, letter weight, and applicable mailing date.

Upload your completed spreadsheet and map the spreadsheet columns to the appropriate mailing fields.

The system then displays your imported records so they can be reviewed before the batch is processed.

4. Validate and Review Your Batch

Review the recipient information and mailing options before purchasing the labels.

Correct any records identified as needing attention and verify the total batch cost.

For large mailings, we recommend processing a small test batch first before approving hundreds of records. This helps identify spreadsheet formatting or data problems before the entire mailing is processed. The site's batch-file specifications similarly recommend testing a few labels before a major mailing.

5. Process, Download and Print Your Certified Mail Labels

Once the data is confirmed, process the batch and download your completed Certified Mail labels.

Print the labels from your office and attach them to the corresponding mailpieces for USPS mailing.

Every Certified Mail piece receives its own unique USPS tracking number, allowing individual letters within a large batch to be tracked separately.

Bulk Certified Mail - No IT or Programming Skills Required

The primary advantage of Excel batch processing is simple: you enter the mailing data once.

For example, if your engineering firm needs to mail 400 notices, you do not need to create 400 Certified Mail labels manually.

Prepare the 400 recipients in your spreadsheet, upload the file, review the records, and process them as a single batch.

For organizations sending Certified Mail regularly, this can eliminate hours of repetitive data entry while helping standardize mailing procedures.

Create Up to 1,000 Certified Mail Labels Per Batch

Certified Mail Labels supports batches of up to 1,000 Certified Mail labels at one time.

Need to send more?

You can process additional batches as required.

This makes Excel Batch Processing suitable for both occasional bulk mailings and organizations that regularly send hundreds or thousands of compliance-related communications.

Every Certified Mail Letter Gets Its Own USPS Tracking Number

Bulk processing does not mean giving up individual tracking.

Each Certified Mail label receives a unique USPS tracking number. Your organization can monitor the status of individual mailpieces from acceptance through USPS delivery events.

Rather than searching through paper receipts, authorized users can access Certified Mail tracking and mailing records through their account.

Maintain Certified Mail Records for 10 Years

For legal and compliance mail, printing the label is only the beginning.

Certified Mail Labels maintains a searchable 10-year tracking archive that can retain mailing and delivery information associated with your Certified Mail transactions. The service also makes delivery confirmation and Return Receipt records available through the customer's account when applicable.

This can be particularly useful for organizations that need to research a mailing months or years later.

Your historical Certified Mail records can help document:

When the letter was mailed
The USPS Certified Mail tracking number
The delivery address
USPS tracking activity
Delivery or attempted-delivery information
Electronic Delivery Confirmation
Return Receipt records when purchased
