View emails in our inbox

As soon as we access Roundcube, the screen shows us the Inbox of our email. It will mark in bold the emails that have not been read, and to the right, where all the folders are broken down, it will indicate a number in case any of the emails containing that folder are also unread.

If we click on an email, a window will open, allowing us to see the content of the message. If we click on the Update button, it will update the received emails. Normally, we do not have to do this, since when an email is received, it updates automatically within seconds.

To compose an email, we just have to click on the Compose button. As soon as we click, it will take us to a screen to compose the email, indicate recipients, ...

When we click on the button, the following window will open, where we can indicate recipients, add hidden recipients, add attachments, ... When we finish composing the message, we can send it with the Send button.

If we have received an email that we want to reply to, we enter the Inbox, click on the email we want to reply to, and click on the Reply button. When we click on the button, the screen for replying to that email will appear.

The same data will appear as if we were composing a new email, however, the Recipient is already indicated, the subject indicates Re: and the original subject, and the Message body shows the thread of the entire conversation held.
When we have everything confirmed, we click on Send to reply to the email.

Roundcube allows us to add signatures to our emails, to add some predetermined message at the end of the email. We can manage this by entering Settings, at the top right.

When accessing Settings, in the right-hand side menu, we click on Identities. Inside, the account will appear, we click on it. When we click, a window opens where we have a section called Signature.

Inside this, we can add our signature, even create an HTML signature if we click on the HTML Signature option. When we finish, we click on the Save button, and we will have our signature in the email.
