About International Mail Service

On October 22, 2015, International Mail Service Inc (IMS) celebrated 25 years in the business of processing foreign mail and packages.  Over that time we’ve maintained the same ownership group and philosophy – provide customers cost effective services and ease of use.

Our customer base has grown to include large printers/publishers, fulfillment houses, universities, domestic mailers, associations, religious organizations, and E-Commerce ventures of all sizes.  You can find IMS customers in almost every state and some foreign countries.

While our parcel business has grown quickly over the last few years, we’ll always be able to process your post cards, letters, and flats too.  Our close relationship with the United States Postal Service (USPS) allows us to offer unique services at highly discounted rates.  Utilizing the USPS means you’re going to get consistent delivery to every country in the world – not just a few industrialized areas.

The attention to detail and customer service IMS provides is unparalleled in this industry.  We make a strong effort to insure that your mail and parcels leave our building with a complete address and your invoice is comprehensive and accurate.  If there is an issue with your mail or packages, we’ll either fix it or contact you to make it right.  We take the “Gatekeeper” responsibility very serious.

If you call our office with a question or quote request, you’ll have a response normally within an hour or two.  Our Sales/Service Representatives can consult on design and service recommendations to insure the best possible value.

Our employees remain a very important part of IMS and we’re very proud of all of them.  They create and employ efficiencies that may go unnoticed to most but allow us to keep costs to a minimum while enabling quick turnaround for your mail and parcels. 

Hopefully this site will educate and serve as a valuable reference tool.  Please let us know how you like it and if you ever pass through Kalamazoo, well, you better stop!

  • USPS Improved Inquiry & Claims Process Open or Close

    The Postal Service has updated its international inquiries online application to better serve customers.

    U.S. customers who are registered usps.com users may now file an international inquiry regarding their lost or damaged packages. If the result of the inquiry is claim-eligible, an international claim will be initiated automatically.

    The update changed the international inquiries online application on usps.com so it requires users to upload their “evidence of mailing” and “evidence of value” documentation during the inquiry process.

    This improves the process for customers because they won’t have to wait to receive an international claims packet via mail, to be completed and returned with supporting documentation.

    Additionally, customers may check the status of their inquiries and claims online 24 hours a day, seven days a week.

  • 5/7/19 Unrest in Israel causing delays Open or Close

    The designated operator of Israel, Israel Postal Company, asks us to inform other Union member countries and their designated operators that, due to the security situation, there have been interruptions and delays in the distribution and collection of mail (letter post, parcels and EMS) in the south of Israel since Saturday, 4 May 2019.

    Israel Postal Company thanks all member countries and their designated operators for their understanding. It will update them via EmIS once the situation has returned to normal.

  • 1/21/19 The difference between IPA and ePacket Open or Close

    What's the difference between IPA and ePacket?

    We often have this conversation with prospective customers - how are these services different?  International Priority Airmail (IPA) and Commercial ePacket (CeP) are both services of the United States Postal Service (USPS) and are best utilized by consolidators like IMS.  By creating large volumes and having the processing expertise, we can provide the best possible rates and delivery of your packages.

    There are both similarities and differences ......

    • ePacket offers door to door tracking, IPA packages only get an acceptance scan upon entry in Chicago (Endicia users).
    • IPA offers options for Letters, Flats, Packages, and M-Bags (printed matter over 4.4 lbs).
    • ePacket is for Packages only.
    • IPA offers service worldwide, ePacket goes to 36 of the most popular countries (and adding more).
    • Both services travel the exact same paths to ultimate delivery in an average of 3-7 days.
    • Both have maximum piece weights of 4.4 lbs.
    • At basic published pricing, IPA is up to about $1.00/pkg cheaper than ePacket for lightweight packages.  But when you get over about 1 lb to most countries, ePacket is actually cheaper and provides full tracking!
    • Most of our customers will use ePacket for all qualifying countries, and IPA for the ROW.
    • We can integrate with the most popular software vendors (including the whole Stamps.com family) to make these services available on YOUR work stations.
  • 1/21/19 Key advantages to using IMS Open or Close

    We all know that price in this industry is paramount to choosing a vendor partner.  But we also think that it's the other things that set IMS apart from our competitors!  We like to think that we take "good service" to a completely different level.  Here's some unique advantages we provide our customers .....

    • Unparalleled Customer Service.  Only our customers truly know the experience, but I can guarantee that you can talk to a real person any time (normal business hours).  We go to great lengths to have a quote or answer to a question within an hour or two - if not immediately.  You'll also get my cell phone number for those evenings or weekends when business owners or managers are often still working.
    • Daily pickups nationwide and all-inclusive pricing available to customers of ALL sizes.
    • Expertise.  We've done nothing but process international mail and parcels - for 28 years.  We've built this business from the ground up and include many innovations that are very unique to our industry.
    • Accurate and timely invoicing.  Through the development of a highly customized ERP system, invoices and mailing statements are 100% accurate and literally available at our fingertips.  This allows us to invoice the same day as received if our wholesale customers are waiting to invoice their customers.  We can also provide line item detail for packages showing the exact weight and cost (even including a comparison to USPS Retail rates for comparable services).
    • We track a lot of packages so we can help set customer expectations.  We can also provide data on YOUR packages when requested (we provide this for all new customers).  We can also provide country specific information on both delivery and delivery scan rates which average about 95% via our ePacket service.
    • There are also many things we do to insure timely entry and delivery that go unseen.  We go to great lengths to fix bad addresses - not even a single package gets by us if it's missing an address component or if routing "issues".  Trust me, we've seen and handled it all!

    If ever in the area of Kalamazoo (SW Michigan) and it's not "blizzarding", stop and see us - we love company!

  • 1/14/19 (Updated 1/18) Snowfall in Switzerland affecting deliveries Open or Close

    Sent: Monday, January 14, 2019 8:55 AM
    Subject: Switzerland – Partial disruption of postal services
    Importance: High

    The designated operator of Switzerland, Swiss Post, asks us to inform other Union member countries and their designated operators that heavy snowfall is affecting delivery in the Alpine region of the Canton of Graubünden, in the eastern part of Switzerland. Closed roads and strong avalanche warnings are making it difficult or even impossible to deliver postal items in postcode areas 72xx, 73xx, 75xx, 76xx and 77xx. It is currently not possible to predict when normal postal operations will resume as the snowfall is expected to continue over the next few days.

    Swiss Post thanks all Union member countries and their designated operators for their understanding. It will inform them via EmIS once the situation has returned to normal.


    Update 1/18/19:  Further to EmIS 7/2019, the designated operator of Switzerland, Swiss Post, asks us to inform other Union member countries and their designated operators that the weather in the eastern part of Switzerland has stabilized. Postal operations resumed on Thursday, 17 January 2019, with the exception of a few homes that remain isolated.

    Swiss Post thanks all Union member countries and their designated operators for their understanding.
