Roundcube vs. Desktop Email Clients
Roundcube is ideal for situations where you need quick access without installing software, but for daily heavy use, consider pairing it with a desktop email client like Outlook or Thunderbird. Using IMAP, your emails stay synchronized between webmail and any connected clients, giving you the flexibility to use whichever method is most convenient at the time.
