You can test message delivery by sending a proof to a previously created seed address.
Sending a proof involves the same process as for a regular delivery (for more on this, refer to this section). However, to send a proof within Message Center you need to carry out the following operations beforehand:
To send the proof:
Click the Send a proof button in the delivery window.
Analyze the delivery.
Correct any errors and confirm the delivery.
Check that the message was delivered to the seed address and that its content complies with your configuration.
Proofs can be accessed in each template via the Audit tab.
