Sending Data Files

When sending us a list, we prefer to receive it in the following formats:

Microsoft Excel – .xls or .xlsx

Commas Separated Values – .csv

Tab Delimited – .tab

Database Format – .dbf 

If you can not get your database to export into one of these formats, there are many other formats and database programs we can work with it, but it may take additional time to complete the data conversion process.


The fastest way to get files to us is by emailing them directly to us as an email attachment. If the file is larger than 10mb in size, you should compress the file using a file compression utility such as Zip or WinRar.


We can also accept files directly at our office or via mail on a CD, DVD, USB flash drive, or most other portable media formats.

Permit Information

A permit imprint or indicia is simply an easy way to apply and pay for postage that doesn’t involve stamps or metering. The postage due for a permit imprint mailing is not actually paid for until the mailing is submitted for processing at a USPS BMEU facility.


If you do not already have your own mailing permit, you can use our permit free of charge when we process your mailing. This is a $235 annual savings for your company.


If you are designing your own mail piece, or are working with a printer to have it designed, you can have our permit indicia put directly onto your mail piece. Click below to download and view our Permit samples in a printable or mailable PDF format.

Frequently Asked Questions

How many pieces of mail are needed to do a bulk mailing?

Presorted Standard and NonProfit mailings require a minimum of 200 pieces or a minimum weight of 50 pounds. Presorted First Class mailings require a minimum of 500 pieces.

How much space is needed on my mail piece for the address to be imprinted?

The clear area needed for the address block should be at least 2″ high x 4″ wide to ensure all of the address components that are required will fit. It is best to work directly with us or the printer when designing your mail piece due to the number of postal regulations that must be strictly followed to ensure that your mail piece qualifies for automation rates. 

How many tabs are required for a folded mailer or newsletter?

Tabbing regulations are constantly changing, so it is best to always check with us for the latest tabbing automation requirements. In general, a folded newsletter or mailer should have two tabs placed on it, usually within one inch of either side. Some types of mailers however can get by with just one tab, and some types are now even required to use the larger 1.5″ tabs on up to 3 sides for full closure of the mail piece.
