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!

  • Commercial ePacket, tracking for half the cost of USPS First Class Package International (updated 7/20/18) Open or Close

    What is Commercial ePacket (CeP)? It’s a relatively new service from the United States Postal Service that provides door to door tracking to 36 countries (as of 2/11/18) with more being added.  The service is only available for small packages containing merchandise and weighing 4.4 lbs or less.

    HUGE SAVINGS! Compared to First Class Package International (FCPI), our all-inclusive rate for CeP will save you 50% or more.  Your savings will vary by piece weight and destination country.  This is a mere fraction of what you’d pay for other trackable services like PMEI and PMI.

    Countries served (effective 2/11/18):

    Australia, Austria, Belgium, Brazil, Canada, Croatia, Denmark, Estonia, Finland, France, Germany, Gibraltar, Great Britain, Greece, Hong Kong, Hungary, Ireland, Israel, Italy, Japan, Latvia, Lithuania, Luxembourg, Malaysia, Malta, Netherlands, New Zealand, Norway, Poland, Portugal, Russia, Singapore, South Korea, Spain, Sweden, Switzerland

    How do customers use the service?  IMS can integrate with the most popular types of shipping software to print the unique CeP labels and facilitate the package data transfer.  Once enabled (usually takes a week or less), you can begin using the service immediately.  For most integrations, there's no cost or revenue obligation to the customer.  IMS will sort your packages by country and apply our permit imprint to pay for postage.

    What can you send? You can send packages weighing up to 4.4 lbs with a value of $400 or less. The packages must be rectangular in shape and the total of length, height, and thickness cannot exceed 36″ (not greater than 24″ in length alone).  Minimum size is 6″ x 3″ x 1/4″.

    Tracking packages: The USPS tracking number sequences are preassigned.  When you generate an order or package label, the “LX” prefixed number appears on your manifest and shipping label so you can pass this on to your customers immediately.  Packages can be tracked direct from USPS.com.

    What is the cost? You get tracking and 5-6 day delivery (worldwide average) with savings of 50% or more off the cost of First Class Pkg Intl postage alone.   Your savings will vary by destination country, weight, and overall volume.

    How to get more information: We would be happy to provide a quick analysis of your costs if you can provide a profile of your package weights, quantities, destinations, etc.  Call our office at 800-466-6245 or email Mark Bouman.  You can also browse our web site to get more information about CeP or any of the other mail and parcel services we offer.  Thank you!

  • 3/2/18 Snowfall in the UK causing major disruptions Open or Close

    Royal Mail (GB) wishes to share the following :

    The designated operator of the United Kingdom, Royal Mail Group, asks us to inform the designated operators of other UPU member countries that significant snowfall has caused major disruptions to transport services across much of the United Kingdom. There is a red weather warning for heavy snow showers and drifting of lying snow along the central belt of Scotland. As a result, Royal Mail Group has had to close its Edinburgh, Glasgow and Perth depots overnight, with no parcels leaving or arriving on the morning of 1 March 2018.

    Red weather warnings are also in place for Storm Emma, which is expected to cause heavy snow and drifting with strong winds across South West England and South Wales later in the day on 1 March 2018.

    Amber weather warnings are in place for frequent and heavy snow showers across much of Scotland, North East and North West England, the East Midlands, East Anglia, South East England, Southern England and the West Midlands.

    Where it is safe to do so, Royal Mail Group is delivering and collecting as normal, but there is likely to be significant disruption to services across most of the United Kingdom, with the result that same-day ad-hoc collections and delivery service guarantees nationwide have been suspended on 1 March 2018.

    Furthermore, congestion at the Channel crossings is still causing delays for all Royal Mail export services to mainland Europe, and Parcelforce Worldwide guarantees on export services are suspended on Euro Priority and Global Priority services to all mainland Europe, the Channel Islands and the Republic of Ireland on 1 March 2018.

    Royal Mail Group thanks designated operators for their understanding and cooperation and will inform them as soon as the situation returns to normal.

  • 2/20/18 Guatemala shut down indefinately Open or Close

As a result, international letter-post, parcel-post and EMS services (inbound and outbound) will continue to be disrupted for at least another four months (end of June 2018).

    Correos y Telégrafos asks operators to continue to hold items to be sent to Guatemala until services have been re-established.
