Practical ways you can use Mailchimp and Microsoft Office 365
Add new Mailchimp subscribers as Office 365 contacts.
Keep your contact lists synced. When a new subscriber is added in Mailchimp, Zapier will automatically create a new contact in Office 365, ensuring all relevant contact information is easily accessible for seamless communication.
When a Mailchimp audience member unsubscribes, Zapier will notify the engineering team via an Office 365 email. This can help with identifying trends or addressing technical issues causing user's opt-out.
Send marketing alerts for Mailchimp campaign email opens.
Track email engagement effortlessly. When a recipient opens an email from a Mailchimp campaign, Zapier will send a notification to your Office 365 email account, helping the marketing team focus on leads that are actively engaging with content.

Frequently Asked Questions about Mailchimp + Microsoft Office 365 integrations
New to automation with Zapier? You're not alone. Here are some answers to common questions about how Zapier works with Mailchimp and Microsoft Office 365
How do I set up an integration between Mailchimp and Office 365?
To set up the integration, you'll use our platform to connect Mailchimp with Microsoft Office 365. Start by selecting triggers such as 'New Subscriber' in Mailchimp, and then choose actions like 'Create Contact' in Office 365. Follow the prompts to authenticate both platforms and map fields accordingly.
Can I automatically update my Office 365 contacts when a new subscriber joins my Mailchimp list?
Yes, you can configure the integration to trigger an action in Office 365 whenever a new subscriber is added in Mailchimp. Set 'New Subscriber' as the trigger event, and 'Update Contact' as the action.
Is it possible to send an email through Office 365 when Mailchimp sends a campaign?
Absolutely. You can set a trigger for when a campaign is sent from Mailchimp so that it initiates an action in Office 365 to send an email or perform other related tasks.
How do I handle bounced emails from Mailchimp with this integration?
Set a trigger for 'Email Bounced' on Mailchimp, which can then initiate actions like updating or labeling contacts in Office 365. This helps in managing your contact lists proactively.
What happens if I remove or update a contact on either platform?
You can choose triggers such as 'Contact Updated' or 'Contact Deleted' from either Mailchimp or Office 365 to ensure changes are reflected across both platforms seamlessly using our tools.
Can we synchronize email list segments between Mailchimp and Microsoft Office 365?
Yes, you can use triggers like 'Segment Created' or 'Updated Segment' in Mailchimp and align these with specific actions such as creating groups or lists within Microsoft Office 365.
Is there support for handling attachments when integrating these services?
Currently, our system supports passing basic text content through triggers and actions but does not fully support the direct transfer of files or attachments within this specific integration setup.
