In your Account Information, you’ll see an area where you can customize some contact details. One of these is the “Invoice email address.” This is the email to which we send your account’s invoices.
By default, this address is the one you signed up with. But emails change, so you may need to update it. You might also want it to be something specific, like firstname.lastname@example.org.
To let us know exactly where to send your invoices, just change— and then confirm— the “Invoice email address” email in these settings.
If you don’t add a custom address or leave the field empty, invoices will go to the email address you signed up with when you created your Customer.io account.
