Mail merge with attachments in Outlook

If you work in Microsoft Office and sometimes need to send out large, personalized mailings, you probably know that the basic package provides the essential means to achieve this task. The Mail Merge feature, introduced in Word 2002, has proven to be an invaluable tool for performing this type of business correspondence for a stupendous number of people.

If you send out massive staff notification mailings or business offers to your clients, if you manage a recruitment agency with a massive database, or even if you just find that personalized newsletters are a necessity – nothing else available in Office really comes close.

Mail Merge in Word

Mail Merge has the ability to produce a virtually infinite number of copies of the same text document with any given user-defined personal variables. For instance, if you intend to send basically the same document as an email message to a number of recipients but include the personal information such as first and last name, home and business addresses, etc., you can do it as professional and accurate as possible using Mail Merge’s personalization tools. These tools allow to keep both the anonymity of other recipients from each other, and to greet each one of them using their own names and titles in the message body.

Mail Merge in Word

This is scenario is done by conveniently placing the user-friendly macros beside the greeting lines and other critical points of the message during its composition in Word. Later, during the actual mail generation, Word accesses the designated contacts base – either the regular Outlook Contacts storage (thanks to the seamless integration between these Microsoft Office components) or an external data-source file (it could be any database-enabled file format – a Microsoft Access file or an Excel table, to name a few) and inserts the actual individual data of the recipient instead of the macro. As the result, each recipient will receive your intended message as if it were designed exclusively for him or her, with only their email address visible in the “TO:” field of the message and their own names and other individual data instead of the placeholders.

We at MAPILab have been working to improve the Mail Merge tool and its personalization possibilities even further, and are introducing the Mail Merge Toolkit: a feature-rich add-in (a software upgrade which uses Microsoft Office as the main platform, while only including the necessary software library files as an addition to the primary pool) that aims to extend the list of available features with its own unique mass mail personalization and productivity functions.

Mail Merge in Excel

One of the most important and welcome additions has been the inclusion of the individual attachments in Mail Merge. Mail Merge with attachments opens even more possibilities to conduct business correspondence precisely and competently. The know-how is simple: to perform a mail merge with attachment, a file location is included beside the intended recipient in the data-source file, and after that – a special macro is specified within the extended Mail Merge finalization window’s “Attachment” field. A Mail Merge attachment will be sent and delivered to the unique recipient as seamlessly and conveniently as a regular file attached to an email message would. If there is no more than one unique recipient per attached file, you can even name your Mail Merge attachments according to the person who is going to receive it (multiple recipients who are going to receive the same file, or even split bunches of recipients and different bunch-dependent files are possible with the Mail Merge with attachments feature as well).

  1. This looks pretty good, and after one or two false starts I managed to get it to work, but ahead of sending each e-mail it asked me to confirm that I wanted to send it, and there was no “yes to all” button, so I had to confirm them individually, which rather put a damper on the bulk mail idea – any suggestions?

    1. Hello Peter,
      Thank you for your question.
      Do you mean a dialogue which requests you to select your Outlook Contacts folder for every message ?
      This issue is known in some email account configurations if Outlook Contacts are used as the recipient data source, and an external file (e.g. an image) is used in the document/message body as well: Word connects to the image, and looses connection with the Outlook data source…
      We know some tricks allowing to solve that issue with Microsoft Office components: the easiest one is to use the regular Word option “Embed image” instead of inserting/linking to the image file.


  2. I’m trying to use the attachment feature, whereby I can put in the file path into the excel spreadsheet, but it is not working for me. How do I put in the file path, so it will email it!

    1. Hello Nikki,
      Thank you for your message.

      In order to let our add-in attach your file to your messages, you will need to type full file name in your Excel data source, which includes Path+ filename.extension, e.g.:


      Please make sure your data source contains full file name – with the file extension.

  3. I have tried the above path+filename extension but no attachment is sent.
    Email is sent to address as are all the field merges in the email but no attachment is sent with the email.
    please assist.

    1. Hello,

      Please consider creating a trouble ticket in our dedicated Support module:

      In the meantime, please identify the stage at which does the issue occur. Temporarily disable the “Send immediately when connected” Outlook option via ‘File -> Options -> Advanced’, and check the Outbox folder. Does the attachment appear to be present?

      Please forward your reply to the Support area.

      Thank you.

  4. But it seem that only one attachment could be attached on each email.
    It seems there is no methods to attached more than one file for one email.

  5. Hello Remiko,
    Thank you for your question.

    You can attach as many files as you wish to your individual messages: please click on the “…” button next to the “Attach” field.
    New dialogue window will open – for managing all your files in the list: attach static files, add your data source field with the path to your file, and remove your previously added files from the list.
    Please see the screenshot:

    1. Hello Vinodkumar,
      Thank you for your question.
      Mail Merge Toolkit generates messages with attachments from within Word and Publisher and delivers them to Outlook.
      If your files are password protected, you can attach them to your messages as well.

      But if you need a tool to protect your files with passwords upon sending them – you will need a tool for Outlook.
      We offer such option with another our Outlook add-in – Attachments Processor:
      you can configure add-in rule to zip files in outgoing messages (filters can be set as well), and the add-in is able to archive outgoing attachments to password-protected zip-files. You can configure the password in the rule settings:
