Email signatures are generally used to display the sender's name and contact information at the end of an email. Sometimes they are used to give website links or even memorable anecdotes. Regardless of what you wish to make your signature say, it is much easier if this content is automatically added to the end of every email instead of having to add it manually for each email. Below are instructions that teach you how to add your own custom email signature within your RoundCube email client.


Creating an Email Signature in RoundCube

  1. Log into your Webmail dashboard and choose the RoundCube option.
  2. From the RoundCube dashboard, click on the Settings option in the upper right corner of the screen.
    webmail preferences
  3. This brings you to the RoundCube Settings screen. Locate and click on the Identities tab.
    webmail identity setting
  4. You are now on the Identities list screen. Find and click on the desired identity in the left hand panel. In this example, there is only one. Clicking on the identity brings up two tabs in the right hand panel. Click on the Signatures tab.

    Standard Signature Box:
    create a signature in Roundcube Webmail

    If you wish to use HTML in your signature, simply click the HTML Signature checkbox. This will cause the Signature field to display as shown below, allowing for special formatting.

    HTML Signature Box:
    Formatting a signature in webmail

  5. Enter your desired custom signature in the Signature field. Once entered, click on the Save button located underneath the tabs.
    Record your new webmail signature

    You have now created your new email signature! Below is a screenshot of how the signature automatically appears when you create an email.

Congratulations, now you know how to create an email signature in Roundcube!

How can i add an image to it

Hello Emperor Bethel,

You would need to store your image in something like Google Drive or your web server and then use the HTML signature option listed in the instructions above. You could then add an image tag in HTML in your signature. Anyone using an HTML editor to view your email will be able to view the image. Here's an example of an html image reference:

Storm Trooper cats

There are many ways to store an image online. You can store it through your account by doing the following:

  1. Open the cPanel for your hosting account with us

  2. Open the file manager and then upload the file you want to use to your public_html folder. Remember that the graphic should be tiny because it's going at the end of an email

  3. When you have finished uploading the file, make sure to take note of WHERE you placed it. If you put it in the PUBLIC_HTML folder, then the file can be referenced with your domain name directly. For example: Write down the path so that you can use it as for you image link.

  4. Go back to your Round cube editor and add the image link in html as per above.

That will complete adding the image to your email. For further assistance using File manager in cpanel, please go to cPanel File Manager.

I hope that helps to provide the information you need!

After following exactly the procedure i do see my company logo in my signature but IN THE SETTINGS. So I "save" and send a test email to make sure but the logo is missing in the email I get.....! 

Can anyone explain this...? 

Thanks for your help

It sounds like it is not either sending or receiving proper HTML within the email. Do you have both the checkbox to enable HTML signatures enabled as well as are you using a mail client that has HTML emails enabled? Some mail clients will also block individual parts of the message as well so you will want to ensure that the image is not being removed within the mail client.

I am having two issues trying to set-up my email signature:

1. The format sets up as double spacing and I cannot adjust it to single.

2. When I have completed my entery and hit save, it tells me to enter a correct email address??? In the content of my signature is my email address.

Thank you for your assistance,

By default, the editor will indeed double space the signature. If you want to add a single space, hold down the Shift key while pressing Enter and it will create a single space. The reason you may be getting the error stating that you have an incorrect email address could be due to the Email field that is also on this page. Be sure that within that field, your correct email address is defined.

RoundCube unfortunately doesn't support the <iframe> HTML tag. You can use inline CSS within your RoundCube signature, such as this example:

<p style="color: white; background-color: blue;">- Jacob</p>

Which would result in your signature looking like:

- Jacob

Please let us know if you have any other questions at all.

I'm just using a basic text sig. When I go to compose an email, Roundcube inserts two or three dashes just above the signature. Kind of annoying to have to delete these and it seems to random if it is two or three. 

There is nothing in the code to put them there:

<p>Chris Lastname<br />Office Assistant<br />Brothers Mfg.<br />(XXX) XXX-XXXX</p>


Any ideas on getting them disappear? Thank you!

Hello Dirtworship,

Thank you for your question. There is no "built-in" option for removing this from Roundcube, at this time.

There is a ticket open for this option, in the official Roundcube "Feature Request" system.

If you have any further questions, feel free to post them below.
Thank you,

Thanks for the link, John-Paul. Too bad I can't experiment with the patch or workaround since I use webmail to access Roundcube. I know from a development sense, it's small potatoes, but from a user standpoint it means irritation every time an email is composed, which--in a regular work day--is a lot.

Hello Dirtworship,

Sorry for the headache with the Roundcube webmail client. As per John Paul's reply above, the actual author(s) of the software has a support ticket request regarding the issue already. We are a web hosting company and not the actual developer of the software, but the issue has been brought to the attention of the developer and we hope to see a modification made to accommodate you in the new feature.

I'd like my signature image to be an attachement to the mail, not some outsourced file. How do i do that?

At the moment the code for embedding the picture is like this:

<p><img id="_x0000_i1025" src="/support/./?_task=mail&amp;_id=207042581653747d59416e4&amp;_action=display-attachment&amp;_file=rcmfile4041400143193047095300" alt="" width="259" height="100" /></p>

It is copied from another signature within our company, but it doesn't work with my mails - the image doesn't add itself to new e-mails. How do i make it happen?

I have set up an email signature but it doesn't show with images and links when I am writing. It shows properly on the signature settings page with my logo and links, and the HTML option is cliked. I used an online HTML signature creator, then copied and pasted the code generated as prompted. What am I missing?

Hello Omolara,

To place a hyperlink in the HTML signature for Roundcube, first simply enter the text you want to turn into the link. Next, highlight that text and you will see two buttons highlight in the toolbar. The leftmost is to create a link while the rightmost is to remove a link. Click the left. A box will pop up and you can enter the URL that the link will point to. Be sure to start it off with http:// or https:// so it will know it is a link. Click the Insert button and that will do it.

Kindest Regards,
Scott M

To do so, you would simply use HTML. The code would look something like the following:

Hello Tammy,

To do that you would perform the following starting at Step 4.

  1. Click on the HTML icon which is for editing HTML source code.

  2. In the pop-up HTML Source Editor window, enter in the following code replacing this image path with your own:
    <img src="">

  3. Click on Update to be dropped back to the signature editing page.

  4. Then click on Save to save the signature.

  5. Now once this has been done you'll want to click on Settings up at the top-right.

  6. From the left-hand menu click on Composing Messages.

  7. Then on the Compose HTML messages drop-down menu, select Always, and then click on Save.

Kindest Regards,
Scott M

Hi there,

Also how to link roundcube with my google email so I don't have to shift around


Many thanks.

Hello Jenny,

Color is only doable if you are using HTMl formatted emails, so be sure they are set to compose in HTML.
As Roundcube is a server side client, it only connects to your email addresses on the server. While you can set Gmail up to pull from the server, it does not work in reverse.

Scott M

I'm having trouble adding an image to my signature. I've uploaded the image I'd like to be a part of my signature under the public_html folder. I don't know how to add the code into the html source code, however.

Would it be <image>

Thanks for responding so quickly. I have inputed the code into the HTML source, but no image appeared. I've also turned on, "always" for compose html messages.

I'm not sure what I'm doing wrong still.

Hello Steve,

I tried it with my own RoundCube with the exact format you provided (using my own image on my own domain name) and it worked without any issue. Do you have your account set to prevent hotlinking by chance? If you are one of our customers, we can look into your specific account to see what the issue may be, but it should be working as described. We would simply need to know the domain name. You can comment below with the domain name if that is the case (we can remove the domain name before it is public if desired.)

Kindest Regards,
Scott M
