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!

  • 6/16/18 Massive flooding in Japan Open or Close

    The designated operator of Japan, Japan Post, asks us to inform the designated operators of UPU member countries that Gifu, Kyoto, Osaka, Hyogo, Okayama, Hiroshima, Tokushima, Ehime and Kochi prefectures in western Japan are experiencing typhoons, heavy rains and massive flooding, as a result of which many post offices, domestic sorting centres and mail processing facilities have been closed. Some roads and highways in these areas are also inaccessible to traffic, which is delaying the delivery of mail and parcels.

    The affected districts and areas are in the following postcodes (as of 11 July 2018):

    Gifu: 5000000-5099999;

    Kyoto: 6000000-6299999;

    Hyogo: 6500000-6799999;

    Okayama: 7000000-7199999;

    Hiroshima: 7200000-7399999;

    Tokushima: 7600000-7699999;

    Ehime: 7900000-7999999; and

    Kochi: 7800000-7899999.

    Japan Post apologizes for these unavoidable delays. It will keep designated operators informed of the situation and thanks them for their understanding and cooperation.

  • 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.
