What different types of mailing options are available?
The Post Office offers four different mailing options; First Class Stamps, First Class Bulk, Standard Bulk, and Non-Profit.

First Class Stamps allow your mail to deliver just like a letter mailed from your desk. First Class mail arrives within 1 to 3 business days. This method is available for quantities under 500 pieces.
First Class Bulk mail gives you the same delivery promises as First Class Stamps (1 to 3 day delivery) at the bulk rate. This option is available for quantities of 500 or more pieces.
Standard Bulk mail takes longer to deliver than First Class mail, between 2 and 10 days, but is cheaper. We recommend to use this method if you do not have dated material.
Non-Profit mail is only for Non-Profits registered with the Post Office to produce mailings. Non-Profit mailing is the cheapest mailing option, but can take anywhere from one to three weeks and sometimes longer to deliver.

How should I design the mail panel?
The mailing panel needs to be formatted to U.S. Postal Service specifications. When designing, a good rule of thumb is to leave at 3.5" of white space on the right-hand side of the address panel. If you don't have enough room on to leave 3.5" you can leave 2" if you keep 5/8" across the bottom open.

How can I reduce my mailing costs?
There are many ways to reduce mailing costs. The easiest way to save is to mail via Standard Mail instead of using First Class Mail. Standard Mail may take longer to deliver to your customers, but you can save on postage costs.

If you still want the quicker delivery offered by First Class Mail you can create a smaller card to take advantage of the Post Office's postcard mailing rate. A card that is between 3.5 x 5 and 4.25 x 6 falls under the less expensive postcard rate and introduces a savings that larger cards don't offer.

Questions About Mailing Lists
What if I don't have a mailing list?
You can create a mailing list directly from our site! In the mailing section of our ordering page you can select to create targeted lists for either businesses or consumers to help grow your client base. When creating a list you will choose the geographic location you want to mail to then drill down to the specific type of customer you're looking for using demographic criteria. Demographic criteria will allow you to narrow your list based on everything from income to home ownership to hobbies and interests.

Our lists are generated from information that is provided by recognized industry compilers of directories and other sources. These data sources are constantly being updated so you can rest assured that the list you're creating represents the most recent postal data available. You are guaranteed a 90-93% deliverability rate of the addresses it provides.

What if my list contains a large number of undeliverable addresses?
If we notice that there is a large number of invalid addresses in your list (usually 10% or greater), we will contact you. Often there are minor problems in addresses ("Rd." instead of "Ave.", misspelled city names, etc) that can be easily fixed by the software.
