# Email reminders: Delivery Statuses

> Track whether your email and letter reminders are sent, delivered, opened or refused from the customer timeline in Upflow, and learn what each status means.

When sending reminders to your customers through Upflow, you can view the status of your outgoing actions from the customer timeline. Whether it's an email or a letter, track their status to see if your customers have received, opened, or refused them.

In your customer's timeline, you can see whether your email has been opened, received, or ignored, as long as your Deliverability is configured ([learn more](/en-us/collection-and-collaboration/emails/sending-emails-configure-your-domain)). Regarding your letters, you can find out if they have been delivered or are still being dispatched.
