-Calling `beginSend` on the sync client returns a `SyncPoller` object, which can be used to check on the status of the operation and retrieve the result once it's finished. Note that the initial request to send an email will be sent as soon as the `beginSend` method is called. Sending an email is a long running operation, so calling `getFinalResult` on the poller returned by `beginSend` could potentially block the application for a long time. The recommended method is to do manual polling at an interval that's appropriate for your application needs as demonstrated in the sample below.

-Calling `beginSend` on the async client returns a `PollerFlux` object to which you can subscribe. You will want to set up the subscriber in a seperate process to take advantage of the asynchronous functionality.
