Mailchimp + Xero

Xero and Mailchimp integrate effortlessly so that you never need to worry about having to update contact information between the two systems. Using Mailchimp in combination with Xero contacts help ensure you keep in touch with your customers by creating engaging, brand building messages through email, ecommerce and social interactions.

What does this integration do?

It keeps your contacts updated. Any change to your contacts in Xero are reflected in your mailing lists within Mailchimp automatically, including the primary contact phone number. A set of default mappings ensures that the information contained within your Contacts in Xero is set to the correct merge fields in Mailchimp. All you need to do is create the Mailing List within Mailchimp and set it correctly in the installation steps, this integration will handle the rest.

Email can now be sent automatically based on your Xero data. For example, as soon as a customer is 7 days overdue with an invoice, Xero can send a signal (called an event) to Mailchimp which automatically sends an email to the customer reminding them to pay the invoice.

Premium use only

Like the other reviews I am not happy about this as I use Xero and MailChimp in two separate businesses.

Only on premium plans? Seriously
Paul Winstanley
Disappointed that I need to upgrade my account for this integration to work. I have several businesses on Xero and think I spend enough. There is no reason to charge an extra fee for this integration when I have other integrations working for free.
