# My recurring invoices aren’t being sent automatically, and it says there are no contact persons associated. Is it mandatory to provide contact person details?

It is not mandatory to associate a contact person with each customer. However, to send an email, you must associate at least one email address with the customer, and the same email must be selected under _Email Communications_ when creating **Recurring Invoices**.

To verify whether the email address is selected under _Email Communications_:

1.  Go to the _Sales_ module and choose **Recurring Invoices**.
2.  Locate the **Recurring Invoice Profile** that needs to be edited and click the **Edit** icon.
3.  Scroll down to _Email Communications_ and check whether an email address is selected.
4.  If not, select the required email address and click **Save**.

**Insight:** Only future child invoices will be sent automatically if the **Recurring Profile** preference is set to **Create, Push, and Send Invoices** or **Create, Charge, Push, and Send Invoices**. For past child invoices, you can edit the invoice and update the _Email Communications_ to send the email manually.
