Mailing Services

Even though about one-third of the mail handled by International Mail Service goes to Canada, we do offer a full range of services available to every country in the world. While international postage can be confusing and expensive, we can blend multiple services to ensure that you receive a great international postal rate. With the ability to provide you with consolidation services through the United States Postal Service (USPS) and direct injection to most countries, we offer something to fit every deadline and budget.

No minimum mailing of printed matter and merchandise to every country in the world.

Available to every country in the world, these services allow us to mix mail from many customers to create one large mailing (per service) per day. Because of the consolidation process, there are no minimums and the pieces can be different sizes and weights. Printed matter pieces can weigh up to 66 pounds. Merchandise items are limited to a maximum piece weight of 4 pounds. Mail is required to have a USA return address and indicia. Note that dutiable items are required to have proper customs documentation.

Increase responses by making it look like your mailer was sent locally.

A great tool for direct marketers trying to make a mailer look like it came from “across the street,” direct injection is a proven method of improving response rates. We currently offer services to more than 25 countries. Delivery and potential savings will vary by country and service. There may also be minimums depending on service and destination country.

A convenient UK mailing service that promises entry within 48 hours and swift delivery.

With same day linehauls to London from our entry at Chicago O’Hare, we can access the UK domestic mail stream within 24 to 48 hours of entry. We offer 1st and 2nd Class mail, parcels (PacketPost), and publication services.

An affordable remailing option for international mail that uses foreign administrations.

Remail from International Mail Services utilizes foreign postal administrations that are able to offer cheaper international rates to other countries, hence the “remail” name. These services have inherent issues with consistency but provide inexpensive alternatives to some of the higher cost options.

International Business Reply Service is available through the USPS and is very simple to use. Customers can use their domestic BR account with a unique envelope or card. International Mail Service can assist with the design contacts within the USPS. We can also set up a business reply program for Canada. We’ll get you artwork for the reply mechanism, a return address, mailbox rental, and can provide regular sweeps as needed.
