Swift Requires Chilkat v11.0.0+

Insert Email into GMail Folder

See more GMail REST API Examples

Directly inserts a message into only this user's mailbox similar to IMAP APPEND, bypassing most scanning and classification. Does not send a message.

This example will create a Chilkat Email object and upload/insert it into GMail. Then adds the "INBOX" label to the email to make it appear in INBOX

Swift

func chilkatTest() {
    var success: Bool = false

    //  This example requires the Chilkat API to have been previously unlocked.
    //  See Global Unlock Sample for sample code.

    //  This example chooses to load an email from a file.
    success = email.loadEml(mimePath: "qa_data/eml/testEmail.eml")

    //  Upload to GMail (does not send, but just inserts).

    //  IMPORTANT: After uploading/inserting, you won't see the message in the Inbox.
