To round off our Roundcube series I will look at email signatures, identities and the “responses” feature.


Email signatures in Roundcube are a little counter-intuitive. You create a signature via Settings » Identities. When you select your email address you can then change basic settings such as your “display name” (which is the name shown to people receiving emails from you). At the bottom of the page you can create a signature for the identity.

As with composing emails, Roundcube uses plain, unformatted text by default. If you want to use HTML in your signature then you can click the HTML button. This allows you to for instance add an image to your signature.

The signature is automatically inserted when you compose a new email and when you reply to or forward an email. You can change when the signature is added via Settings » Composing Messages » Signature Options » Automatically add signature.


If you want to be able to use different signatures then you can create multiple identities. Each identity can have its own signature, and you can also tweak other settings, such as the display name. For instance, you might have one informal identity using the display name “An Example” and a more formal identity using the name “Dr A. Examplé”.

When you have multiple identities you can set one of them as the default. To use a different identity you can then click Signature when you write an email and select another signature.


Roundcube also supports “canned responses”. If you find that you regularly write (or copy and paste) the same email then you can safe the text as a “response”. When you reply to an email you can then simply click the Responses button to insert the text.

You can add responses via Settings » Responses. Responses you create are listed in the left hand pane, and you can edit responses in the right-hand pane.
