  1. Hi I use roundcube for my work email. I’ve created a html email signature that is great apart from the following issues;

    my text colour is changing to black

    the social media buttons don’t click on and open automatically, I must right click and open link in new page. ( I did shorten my links using

    any help would be much appreciated.


    1. Hi Jenny,

      That is strange and I don’t believe it should be happening unless there has been a change to Roundcube. Are you able to email us a couple of screenshots of the problem to [email protected] and we will jump onto it and take a look for you? In regards to the social links, a lot of email clients don’t allow you to open links directly by clicking on them. Usually, you have to hold down CTRL + click on the link. Not sure if that will be the problem here, but worth a try.

      Speak soon!

  2. Hi i would like to know how to insert a picture for creating a signature?

    1. Hi Jenny,

      It sounds as if your Roundcube is displaying the HTML signature in plain text format. Did you tick the “HTML Signature” box below the signature when installing it? Also, you will need to go into Settings > Preferences > Compose HTML messages > set to ‘Always’ then ‘Save’. This will make the HTML signature display when composing a new email.

  3. For some reason my logo which was saved in the signature( Roundcube) is not displaying in the sent email, only the company information shows up but not the logo. Any advice on that Regards

    1. Hi Jay,

      It sounds like the email is being sent it plain text format. When you look at the email (sent to yourself) can you see a logo in there? Or is it only in the sent items that you cannot see the logo? Please check this setting: Go into Settings > Preferences > Compose HTML messages > set to ‘Always’ then ‘Save’. This will make the HTML signature display when composing a new email.

  4. Hi, I have setup a signature in roundcube and all good except that the line spacing between the lines of text in the signature are very wide. I can’t seem to see how to adjust it so that it looks like single spacing. Help!

    1. Hi Shelley,

      Feel free to send us an email to [email protected] describing the issue with some screenshots, and we will take a look for you. Also, please let us know your account email address so we can check the signature on our end too.
