Direct mail is a breeze with C&C Mailing Service.  As your source for professional mailing services, we ensure that your product is processed in a timely manner and meets all postal regulations.  Better still, we do it at prices you can afford!  Below is a general overview of the work we do in order to obtain postage discounts for our client’s direct mail, beginning with the mailing list and ending at the post office.


Lists are sent to us electronically in many formats, including excel, text files, and CSV.  When we receive a list, we download it into our software, convert your compatible files to our system format, add additional data fields that are required for processing and, if needed, make minor adjustments in the database structure.

All lists are sent to NCOA and are CASS Certified to clean the list, verify the accuracy of the addresses, and prepare for postal sorting. A bad mailing list can greatly increase the cost of direct mail. The costs of printing, processing, and postage increase if there are address errors which are not eliminated. If addresses are not verified for accuracy, many pieces may not be delivered at all. That is why it’s important to use an accurate, up-to-date mailing list.

National Change of Address is an address correction service used to match submitted mailing list information against change of address information for the entire country. If a match is detected, NCOAlink can correct the address before it is printed on a mailpiece. In order to obtain presorted postage rates for any mailing, a mailhouse such as C&C Mailing Service must be able to provide proof that they have updated the mailing list through NCOA within the last 90 days prior to the mailing date.

CASS Certification
Our software will standardize your delivery addresses and add the zip +4 codes for potential postage savings. The barcode is added at this step in the process. The Postal Service has implemented a new barcode called the IMb. Effective 1/28/13 the old POSTNET barcode will be discontinued and all bulk mailings must carry the IMb barcode to qualify for the greatest postal discounts. C&C is currently equipped with the technology to print this barcode and we encourage all customers to complete the necessary paperwork with the postal service in order to be ready for this change.

Remove Duplicate Addresses
As requested, we perform a hard duplication removal on mailing lists that are given to us for processing. Multiple records that have identical name fields will be removed, leaving only one to be mailed.

Computer Presorting
The mailing list data will be sorted according to specific USPS regulations. We do not simply sort your list into zip code order, we sort to a detailed system of delivery paths and entry points. We are able to sort all the way down to walk sequence order for the postal delivery. This means the mail is actually in order for the carrier’s route as he goes from house to house.


We tailor our services to your specific needs for the current job. For each mailing that comes in the door we evaluate the mailpiece and determine what services must be performed in order to deliver each piece to the mailing list provided while meeting postal regulations.

All mail must be properly addressed and meet USPS standards of readability. Whenever possible, we use our high speed inkjet equipment to print the barcode and address directly onto your piece. Addressing directly onto a mailpiece adds a professional appearance to your mail. In certain cases, we print the addresses onto labels first then apply the labels to the mailpieces.

Laser Lettering
We can print your letters with variable data in black and white or full color. When you send us your form letter electronically, we can insert names and addresses or other variable data as we print the letters. We can also generate a gift string to be printed on each letter at the customer’s request. After the letters are printed, we fold, insert, and mail them.

Direct Mail folding, although it seems simple, is an important part of the mail preparation process. If a piece is not folded properly, it will cause problems in the next part of the automated process. Usually, after your direct mail piece is folded, it will be sent to a different machine, typically the inserter. For letters which will be inserted into window envelopes, we spot check the visibility of the address often during the folding process to be certain that the entire address and barcode show through the window.

Machine Inserting
We machine insert different materials, including letters, multiple page brochures, gift slips, and reply envelopes. Our trained professionals will insert up to 5 different pieces into an envelope and seal the envelope all in the same pass. If you have a mailing which will be a match (the letter and the outer envelope are both addressed to a recipient), after the letters and envelopes are printed, we fold and insert with extreme care to be certain that every letter is in the correct envelope. Our machines run at approximately 5,000 completed envelopes per hour. The result is a professional looking mailing without the manual labor.

Hand Work
Product which needs inserted into larger or non-machinable envelopes is inserted by hand. All mailings inserted into envelopes which are 9X12 or larger are hand inserted. Some smaller envelopes, such as those with a square flap, are not compatible with inserting machines, so this work is also done by hand. Other hand work services we provide include collating, hand stamping, inserting into folders or binders, glue dotting, and affixing calendar pages to their backing. Our hand work specialists are a creative bunch, so if there is something you need done, they will figure out a way to make it work.

The post office refers to unenveloped letter sized direct mail pieces as Folded Self-mailers. Standards for construction and mailing of these pieces changed as of January 5, 2013. The goals of these changes are to prevent open edges from jamming the post office’s high-speed processing equipment and reduce the amount of damaged mail. The final fold must be on the bottom of the piece, or on the leading edge of an oblong piece. Pieces must be held closed with wafer seals, which are also known as tabs. The number and size of the tabs used vary, but, beginning in January, we will be required to use a minimum number of two tabs on each piece. The standards for pieces which are stitched (stapled) remain the same, with three tabs required. Any pieces not meeting postal requirements will be required to pay higher machinable rates. The post office has made a complicated matrix of piece size and weight, number of folds, and orientation to determine the number of tabs needed and the placement of the tabs. It’s our job to stay on top of these postal requirements, so be sure to let us handle the processing of these pieces for you.

This is an essential step in preparing standard class mail. At this time we use the information generated in the computer presort. We sort the mail into packages and put it in trays, sacks, or pallets. Each tray, sack, or pallet consists of mail that is going to a specific sorting facility and must be labeled according to strict postal regulations. This is a process which is done at the post office for first class mail. By doing this work in our mailhouse, we are in essence, doing some of the postal service’s work for them. It is this physical sort which enables us to use the discounted standard mail rates on your mailings.


Postage can be applied to your piece in a variety of manners, including indicias, metering, or stamps.

Many standard class mailings are printed with an indicia. This is a small block of text in the upper right corner containing vital postal information. To use an indicia, a permit account must be designated. A permit is an authorization from the USPS for specific types of mail preparation or postage payment. Specifically, it is an authorization to mail without postage affixed by using an indicia. Payment is made against an advance deposit account that is established with the UPSP for postage. C&C holds first class and standard permit accounts with two post offices in the region, and customers without their own account are welcome to use our account for their mailings.

We also have a meter machine which can affix postage. This is used mostly for bulky envelopes that are not preprinted with an indicia. We meter all mail going to foreign countries.

If you want to add a personal touch to your mass mailings, stamps are great way to do that. We have machines that apply stamps directly to your mailpiece. We use coils of stamps sold by the post office in quantities of 3,000 or 10,000 to machine stamp your pieces. For mailings of smaller quantites, we can apply stamps by hand.

Approximate postage per piece is listed below for automated standard class mail:
Letter .22 - .301
Non-Profit Letter .10 - .185


We offer delivery to a number of area post offices. Much of our mail goes to the General Mail Facility (GMF) on the North Side of Pittsburgh. This facility is a Sectional Facility and, for many mailings, we can obtain the deepest discounts here.
