Doing an Email Merge on a Mac with Outlook, Excel, and Word

Software-as-a-Service Alternatives

If you’re an organization doing a lot of targeted mailings and campaigns, you may want to consider uploading your email lists to an online service that will track campaigns and templates for you as well as give your users an easy way to unsubscribe. Here are some examples of those SaaS solutions:

Google Add-ons

There are also some third-party add-on solutions. If you don’t mind the developers having access to your Google information, then you may want to explore these options:

Some other funky workarounds…

This Apple support communities discussion has some interesting other workarounds in Mac OS X for doing an email merge, including using the Mail Merge add-on for Thunderbird.

Microsoft Office (Excel, Word, Outlook) Email Merge

This blog post is really about how to do an email merge using Microsoft Office on a Mac, so here are the steps and considerations. I’m using Gmail as an example, but you can do an email merge with any kind of email account, as long as it can be put into Outlook (Exchange, POP, IMAP, etc.).

Also, please be mindful, since you don’t really have an unsubscribe button in Outlook email merges, that you should still be complying with the CAN-SPAM Act guide.

macemailmerge01 So, with Gmail as an example, go to Settings.

macemailmerge02 Under Forwarding and POP/IMAP, make sure Enable IMAP is selected (you may have to scroll down a bit to see the option).

macemailmerge03 For some reason, Google doesn’t consider Outlook to be secure, so in order to access Google from Outlook, you’ll have to go to and select Turn on.

macemailmerge04 Launch up Outlook and select Outlook > Preferences.

macemailmerge05 Click on Accounts

macemailmerge06 Add whatever account you plan on emailing from. Since we’re using a Gmail account as an example, you would click Other Email.

macemailmerge07 Enter the appropriate information, and then click Add Account.

macemailmerge08 Then click on Outlook and select Work Offline. This step isn’t necessary, but I highly recommend it, because it gives you a chance to spotcheck the merged emails before they go out.

macemailmerge09 Now, launch up /Applications/ and go to Mail and select Preferences.

Unfortunately, Apple has made it so you can’t select the preferences until you have set up at least one account, so you may have to set up your email account in Mail as well, even though we won’t be using it.

macemailmerge10 Under Default email reader, select Microsoft

If you find that Mail keeps reverting the default email client to be Mail instead of Outlook, you may have to run this command:

/System/Library/Frameworks/CoreServices.framework/Versions/A/Frameworks/LaunchServices.framework/Versions/A/Support/lsregister -kill -r -all local,system,user
(Don’t run it prefaced with sudo—just run it as is). Thanks to Max108 for the tip.

macemailmerge11 Make sure your Excel worksheet has at least an email column and another column (e.g., First Name). Save the Excel file some place where you can find it easily later.

macemailmerge12 Launch up Word and under Mailings, select the type to be Letters.

macemailmerge13 Then, select Use an Existing List and find the Excel file you saved earlier.

macemailmerge14 If you created the Excel sheet, you know it’s not malicious. Click OK.

macemailmerge15 Click OK again, unless you’re using another worksheet and have to select that.

macemailmerge16 You can insert values from different columns in the spreadsheet to be dynamic parts of your email (for example, Dear «First_Name» so the person’s actual first name fills in).

macemailmerge17 When you’re happy with how your “letter” (email) looks, select Merge to E-Mail.

If Merge to E-Mail is grayed out, it means Word doesn’t think that Outlook is the default email client. I’ve seen two situations for this—one is addressed with that command in case Mail stubbornly keeps itself as the default email client, and the other is the corresponding Outlook version not being installed. In other words, you can mix and match and use Word 2011 with Outlook 2016 as long as Outlook 2011 is installed.

macemailmerge18 Select the email address header for the To, put in the email subject you want recipients to see for Subject, and then select the message format type (probably HTML Message if you have any kind of bold/italics/color in your message).

Then click Mail Merge to Outbox.

macemailmerge19 This is where the setting-Outlook-to-offline-mode approach pays off, because you’ll see your Outbox populate with the merged emails that won’t send immediately.

macemailmerge20 So it means you can go into several of the pending emails and just make sure they look the way you want.

macemailmerge21 When you’re satisfied with the messages, select Outlook > Work Offine to put it back online again, and then your messages should send.
