Click on the Compose toolbar icon opens the message compose screen. Depending on your settings it opens in the current browser tab or in a new window.
Enter at least one recipient address or select them from the address book, type in a subject and the message text and click the Send button in the toolbar when you’re ready to send the message.
Save it as Draft (toolbar icon) if the message is not yet complete and you’d like to finish and send it at a later time. The email will be stored in the Drafts folder and can be double-clicked there in order to resume composition.
If you want to respond on a received message, click the Reply or the Reply all button in the toolbar or the equivalent buttons in the Preview Pane. This will also open the compose screen but with a quote of the message you’re replying to and with the recipient(s) pre-filled.
While Reply will copy the sender address into To field, Reply all will add all recipients of the original message to the To and Cc fields.
Messages can also be forwarded to somebody by clicking the Forward button in the toolbar. The compose screen will contain the message text and all attachments already added. You can still add more attachments or remove some you don’t want to forward.
The Forward toolbar button offers the following options:
The recipients of the composed message can be freely entered into the To or Cc fields in the header section of the compose screen. Separate multiple addresses with a coma (,). Make sure you enter full and valid email addresses.
While typing a recipient address, the app continuously searched your address book and suggests matching entries right below the input field. Use the cursor keys (up/down) on the keyboard to select one and then hit <Enter> or <Tab> to copy the highlighted address into the recipient field.
If you prefer to select recipients from a list of contacts, use the address book widget on the left side to look them up. First, select the address book to browse on the upper part of the widget and see the contacts listed below. Only a limited number of contacts is displayed at a time so use the arrow buttons in the widget header to jump to the next page of contacts.
Select one or more contacts in the list and then click either one of the buttons below (To+, Cc+, Bcc+) in order to copy the selected contacts to the according recipient field. Double-click a contact in the list to have it added to the To field immediately.
In order to attach files to the message, click the Attach button in the toolbar and then select the file on your computer using the file picker dialog that opens. Attachments to be sent with the message are listed on the right and can be removed again by clicking the Delete icon of the according file.
If your browser supports HTML5, you’ll see the file-drop icon at the bottom of the attachment list. That means you can drag a file from your computer’s file explorer with the mouse onto that icon in order to attach it to the message.
Depending on your settings, the compose screen shows a simple text field to enter the message or a rich text editor with a toolbar that enables text formatting, bullet lists, image embedding and more.
You can toggle the composition mode between plain and rich text (HTML) with the Editor Type selector which is hidden in the sending options bar. Expand the Sending Options by clicking the down-arrow on the left border of the message headers block.
When in HTML editor mode, you can embed images right into the message text. And here’s how to do that:
The message sending options are hidden by default and first need to be expanded by clicking the down-arrow on the left border of the message headers block.
There you can switch the editor type to compose html messages and adjust other settings concerning the message delivery.
