Click "Write Email" on the left side of Sina email page to enter the email page. Show your nickname and Sina email address after the sender. Here's a detailed introduction to the method of writing email: fill in the recipient's address in the address input boxes of recipient, CC and BCC, and you can enter the other party's email address (separated by commas or semicolons when there are multiple addresses); You can also click the blue link in front of each input box to open the Address Book window, select the desired contact or contact group, and then click OK to add the selected address to the input box. It should be noted that the recipient can see the address in "Cc", but can't see the address in "[BCC]". Subject and body of the message Enter the subject of the message you sent in the Subject column, which will be displayed in the Subject area of the recipient's inbox, and it will be displayed as "No Subject" when sent without adding a subject. Enter what you want to send in the input field, and then press Enter to wrap. Send Attachments You can also send files from your local hard disk, disk or CD as attachments to each other. There is no limit to the attached file types, and up to five files can be sent at a time. Enter the absolute path and name of the file to be sent in the area to the right of the attachment, or click Browse to find it. The recipient can open the attachment directly or download it to the local computer through the network. Setting the signature file The content of the signature file will be displayed at the end of the email received by the other party, and the setting content can be made in "Settings Area/Signature File Settings". Of course, you can enter something different from the preset content in Signature, but this change is only valid for the currently sent mail, and the system will still default to the preset signature file content next time. Setting the importance of mail and setting the receipt of mail can help you know the receiving status of mail. If you want to get a receipt, please select the check box in front of "Give me a reply when the other party receives the letter". When you check the email receipt, you can automatically send you an email with relevant information such as what the other party has seen. Send Mail Click the "Send Mail" button, and the system will send the mail. If "Prompt for successful sending" option is selected, after successful sending, the system will display a success message; If this option is not selected, please return to the inbox page after successful sending. Click "Rewrite Mail" to clear the current input and rewrite the contents of the mail. If "Keep a copy in the sent folder" is selected, the sent message will be automatically saved in your sent folder for reference at any time. If you have more questions, please contact Sina Customer Service Center.
