How to Mail Merge with Attachments, Custom Subject & CC / BCC – using Word, Excel, & Outlook?

It is not possible to attach files to Microsoft Word mail merge. The easiest way to do this is by using third-party add-ins such as the “Outlook Mail Merge Attachment (OMMA),” “Merge Tools Add-In,” and “Mail Merge Toolkit.”

Doug Robbins Microsoft Valuable Microsoft valuable professional designed this Add-in which allows users to Attachments, Custom subjects & CC / BCC while mail merge.

Download/Setup Mail Merge Tool in Microsoft Word

In the above explanation, you can only send the email to a different recipient with related information, but in case to attach the file individually, with the help of ADD IN.

Let’s download the file Click Here, before using it, a few customizations are required:

Once your file is downloaded it consists of some PDF files and a Macro Enable Template file, you need to update the file in the internal setting of Microsoft Word, which will enable to Merge Merge Tab.

Open Microsoft Word, click on the Blank Document >> Click on the File tab from the left corner of the screen, then click on Options.

Within the options menu, click on advanced from the left navigation panel, now scroll down to the section general, under general you have something called file location, click on it.

File location dialog box pops up, select the last option startup, and hit modify.

That will show you the location where we want to put the Macro Enable Template file downloaded above. [C:\Users\XXXXX\AppData\Roaming\Microsoft\Word\STARTUP], copy that location and paste it to the file explorer.

Now you have two folders above and the folder consists of the “Macro Enable Template file”, arrange both sides of the folder by side and simply drop and drop the macro file into the Microsoft Word startup folder.

You can also copy and paste the file into the startup folder. Basically, what it does when you open the macro file the next time you open Microsoft Word.

Close all folders and Word, Now Reopen Microsoft Word, and you will see the Mail Merge tab appears in the navigation section.

Step to Mail Merge with Attachments using Merge Tool

Everything is set, Now let’s dive in and understand “How it works”. This method consists of all three platforms Microsoft Word, Excel, and Outlook to perform this.

The role of All three is important, first, you have to prepare the speed sheet, which consists of all the information such as (Name, Last name, email address, file location, email address for carbon copy and Blind carbon copy, amount, due date, etc.)

Microsoft Word with the help of the Mail merge tab connects the data from the speed sheet. I created a sample Excel spread which looks like that:

Open Microsoft Word, click the Mailing tab, click select recipients, and select Use an Existing List from the drop-down list.

Now What I have to do is navigate the speed sheet saved in my system which consists of all the required information.

Keep the check box selected if your First row of data contains column headers, and click OK, that’s why, I have connected my Word Sheet to my spreadsheet.

You can cross-check by clicking on the Insert merge sheet navigation tab and check out all the headers shown there.

You can simply create your draft email message and use this header where you need the name, address, amount is any other related details to be changed for every recipient.

Lets start with creating your email message:

Type Dear, hit the space bar then go to Insert merge filed select First_Name, hit the space bar, and again go to Insert merge filed and select Last_Name.

I have created my own custom email message, which will be like this, you can create your own spreadsheet and email message according to your requirement.

Finally, the email is ready to go, it’s time to add the common attachment and attachments relevant to individual persons using Doug Robbins Addin. It is very important to save the Word file before proceeding.

Click on the Merge tool from the word navigation tab >> Click Merge with attachments.

Mail Merge with attachment tool dialog box pops up, that contains “Select the merge field that contains the path and filename of Attachment.

Now I have to select the unique Invoice for every recipient, so I going to scroll down and select the invoice location (This is the location where I have added a separate attachment for every person and added the location in the speed sheet) from the left selection pane and hit add.

I also want to attach a PDF file that every recipient will get in common, for that click “Browse for attachment to be included with all messages.” select the file from the location you saved, and the location is added.

Next is the merge destination, there are three options Merge to Email Message, Merge to email as Word attachment, and Merge to email as a PDF attachment.

Select Merge to the Email message, and some more options appear:

  • Select the field containing the Email Addresses: Select the Email address from the drop-down list, because you want to send the email to their respective email address.
  • Select the field containing the CC Addresses: Enter the email address and specify in the CC section manually or if your speed sheet consists of the email address of the CC, you can select from the drop-down list.
  • Select the field containing the BCC Addresses: Enter the email address and specify in the BCC section manually or if your speed sheet consists of the email address of the BCC, you can select from the drop-down list.
  • Send using Account: Here you can select the email address already added in Outlook.
  • Send on behalf of: You can enter the email in case you need to send it on behalf of someone else.
  • Reply to Address: Enter the Email address in case you need to reply to a different email account.

Click the Checkbox if you need Request Delivery Receipt or Request Read Receipt, Type the Subject manually in Text for Subject of Email, that subject will be common for every email.

You can also customize your Subject line, every person you mail will get different subject information. Select the checkbox “Data Source contains a Subject Field”.

  • Text before Subject Field
  • Select: that brings a dropdown list, I select policy number because it changes for everyone.
  • Add Space Text after Subject Field.

Now the subject would be “Reminder of Payment of <<Policy_No.>> is due soon“. The policy number will change with every email message.

Click continue, Merge record dialog box appears, you need to specify whether you need to send the email to all or you need to send it to a specific person only.

That will take a second and all the emails are sent to their specific destinations, Mail merging a document with attachments and customized information is easy.

It is very similar to the process for a single document, except that it takes longer.

Mail merge allows you to make multiple copies of a single document with different information to make things easier.

That way you can Mail Merge with Attachments, Custom Subject & CC / BCC – using Word, Excel, & Outlook.

Final Words

In conclusion, mail merge with attachments Outlook 365 is a powerful tool, however, many small businesses don’t use the feature because they don’t know how it works.

Mail Merge can come in handy, especially if you need to mail out hundreds of copies of the same email. Before using Mail Merge, you should first set up a template using Word.

Then, when you’re ready to run the Mail Merge, select the template file you set up in Outlook, and tap Open.
