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 mailing services that are 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.

Ship to over 200 countries worldwide.


Our mailing services allow us to mix mail from many customers to create one large mailing (per service) per day which we sort/sack by country. Because of the consolidation process, there are no minimums and the pieces can be different sizes and weights – including cards, letters, flats, and M-Bags.  Printed matter pieces can weigh up to 66 pounds (over 4 lbs via M-Bag rate).  Mail is required to have a USA return address and indicia.

International Priority Airmail (IPA)

  • Delivery in 3 to 7 days from entry at Chicago
  • Savings up to 50% on cards, letters, and flats
  • Tracking and insurance are not available for this service

International Surface Air Lift (ISAL)

  • Note that while IMS does offer the ISAL service, the pricing has eclipsed that of the above IPA service where delivery is faster – so that’s basically eliminated the ISAL service.
  • Delivery in 7 to 14 days from entry at Chicago
  • Savings up to 40% on cards, letters, and flats
  • Tracking and insurance are not available for this service

Note: To ship packages containing dutiable merchandise, see our “Parcel Services” page.

All-inclusive pricing through Canada Post.


International Mail Service offers a full menu of services direct through Canada Post. Our all-inclusive pricing includes border clearance and entry at Windsor, ON. Canadian mail sent through these services must have a Canadian return address and indicia. This “local” identity can improve responses from Canadians.

Increase responses for mailers.


A great tool for direct marketers trying to make a mailer look like it came from “across the street,” direct injection mailing services are proven for 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, swft delivery UK mailing service.


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 option for international mail.


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 mailing 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.
