Mail Merge Toolkit is a powerful add-in for Microsoft Office extending the mail merging capabilities in Microsoft Outlook, Microsoft Word and Microsoft Publisher. This app allows you to realize really personalized mass mailing easily and efficiently by providing a set of requested and unique features:

	Personalize email subject As soon as you need to personalize part of the message subject or the whole subject line, you need Mail Merge Toolkit. Insert data fields into the message subject, so that not only the contents of a message but also its subject is personalized. The email subject personalization guide is available as a separate article.
	Mail Merge with attachments As soon as Mail Merge Toolkit is installed, you can attach files to the message. Perform the mail merge the same way as you do it usually and click the "Mail Merge Toolkit" option on the last step of the "Step by step wizard" in Microsoft Word to specify the necessary attachments. Read the article about mail merging with attached files for all the details.
	Send personal attachments in mass email Mail Merge Toolkit offers a way to send personal attachments. You just need to specify the path to the file in a separate column in the data source (Excel spreadsheet, CSV, database, etc.) and enter the name of this field instead of the attachments in the Mail Merge Toolkit. See how it works in this short video - Mail Merge with personal attachments.
	Send personalized PDF files Microsoft Word Mail Merge allows you to personalize HTML messages, but what if you need to send it as a PDF? Try Mail Merge Toolkit, the only way to create and send personalized PDF files with a few clicks. You just need a select "PDF attachment" in the message format and fill in the text which will be displayed in the message body. This feature is described in the article Mail Merge with PDF attachments in Outlook.
	Mail Merge with password-protected PDF and DOCX Attachments When sending personalized documents, you can protect secure files with a password. This feature prevents unauthorized users from accessing, copying, editing, and printing sensitive data. Encrypt documents with a single password or different individual ones. See an example in this short video: Password-protected PDF in Mail Merge.
	Change Sender's Email Address Before sending messages, you can change the sender in the From field. When having multiple Outlook accounts, you can choose different emails. Moreover, you mail merge send as someone else if you were granted Send As or Send on Behalf of another Microsoft 365 or Exchange mailbox permissions.
	Multiple recipients per email, add CC, BCC fields When messages need to be sent to more than one email address, you can specify multiple recipients separated with semicolon in your data source or in the TO field directly. Additionally, you add CC and BCC recipients the same way as in regular Outlook messages.
	Track clicks in email campaigns with UTM parameters Measuring email campaign performance is an essential feature for bulk mailing. Mail Merge Toolkit allows adding UTM codes to links and tracking clicks in Google Analytics and similar services. This tells you what emails are driving traffic to your site and helps reach out to people in the most effective way.
	Choose the email format you need Send messages to multiple recipients in PDF, DOCX, HTML, Plain text and RTF formats directly from Microsoft Word.
	Do a Mail Merge by a SharePoint List If the data source with the message recipients data stored in a List on Microsoft SharePoint Server, the Mail Merge Toolkit offers you a way to get data from these lists and use it for mail merging! You do not need to ask your SharePoint Administrator to install something on the server and you do not need to allow the exporting of the list to a Microsoft Excel Spreadsheet. Just use the Mail Merge Toolkit to perform your mailing by getting the data from a known and constant source. This feature is described in the article How to do Mail Merge with SharePoint lists.
	Is it safe to use? How secure is my data? When choosing between email marketing tools, data security is one of the main concerns. With Mail Merge Toolkit your mail lists, message content and attachments are safe and secure. The product is designed as an extension for built-in Microsoft Office features in such a way, that all operations are performed locally within your environment. There are no additional 3rd party servers or services involved, and no data is being transferred to our side in any way.

The Mail Merge Toolkit dialogue looks very similar to the standard Microsoft Office box "Merge to Electronic Mail". In that box, like in the standard one, you can choose the data field containing recipient addresses, set message subject (btw, in Mail Merge Toolkit you can use automatic data field insertion like in a document text), set the format, and choose files to be attached to each message if necessary.

Frequently Asked Questions about mail merging add-in for Microsoft Outlook

Question: Every time I try to send a mail merge with a party CC'd it seems to add an additional CC to my mailmerge. Do you know if there is a way to correct this?

Answer: Our Mail Merge Outlook Toolkit software works as follows: according to the number of e-mail addresses in the "To:" field, Mail Merge Toolkit generates personal messages for every single recipient (as many messages as many recipients in the "To:" field), and then, places all those individual messages into Outlook Outbox. I.e. only "To:" field matters for generating a single personal message. That means, if your original, "source" message contains addresses in the "CC" or "BCC" field - every message generated for a single "To:"-recipient will contain all these addresses in those secondary fields, so, therefore, a (blind) copy of every message sent to a single "To:"-recipient will be also sent to the secondary recipients (specified in "CC" and "BCC"). So, if you add e.g. 100 recipients into the "TO:" field, and a recipient into CC - your CC-recipient will get 100 message copies addressed to your 100 TO-recipients. This behavior is correct. Therefore, we usually strongly recommend our customers to avoid using the "CC" or "BCC" fields if mail merge feature is used.

Question: Does Mail Merge Toolkit enable me to send individualized attachments in the mail merge, so that each email contains a different attachment?

Answer: Yes, Mail Merge Outlook Toolkit will help you attach to your personalized messages unique attachments to unique recipients (or, also static files if needed). With Mail Merge Toolkit add-in, you can merge fields from different data sources, incl. Excel data files: all the opportunities of the native mail merge in Word are supported by our Mail Merge Toolkit since it is the extension of the regular Office Mail Merge feature. Its option appears in the last 6th step in Word, as an alternative towards the regular "Electronic Mail", if you follow Step by Step Mail Merge Wizard, and enables some additional features there. And you can send personalized attachments with this tool - a sample of such use with the Excel base is illustrated in this video tutorial.

Question: Is there a way to send from a non-primary email address? I sent a test email, but there was no option to change the "From" field before sending.

Answer: Our mail merge tool does not provide any possibility to edit the From field. But if you have several accounts in Outlook, or if you have several mail profiles in your system - Mail Merge Toolkit will display profile or account selection dialogue: if you close Outlook before mailing (and do not use Outlook Contacts as a data source) - you will get profile selection before the account selection. You can test with a separate account, or also with a separate mail profile. If you e.g. send through a POP3 account - Outlook will send a message with the address specified as the sender's address in your POP3 account settings. If you send using some specific Exchange feature (delegate access, or "send as", or "send on behalf") - your Exchange Server analyzes data in the From field and processes it according to the sender's permissions to send as the specified user. Please contact your mail server administrator for more details about using these features.
