# Sender field requirements for Email activities

We fixed a bug in the [Email API](https://developer.close.com/api/resources/activities/emails/list) that previously
allowed creating emails without a sender in cases where a sender is required.

The sender field is required for emails with status `inbox`, `scheduled`,
`outbox`, or `error`. It may be omitted in the following cases:

- For `draft`, since the sender can be specified later before sending.
- For `sent`, where it defaults to the email address of the user associated with
  the email or the owner of the API key.

When updating a draft's status to `scheduled` or `outbox`, the sender field is
now required if the email doesn't have one yet.
