Open Google apps (gmail) or Zoho Mail by clicking a link in Zoho Creator

If I have a list of several customers, including their email address, would it be possible to set it up so just by clicking the email adress, so would I automatically open up Gmail or Zoho Mail directly with the list of all the communication with this customer?

Any suggestions how this is done?

Thanks
