Summary
After clicking Validate inside a Journey, users have the option to test the journey. When choosing the Send Type, you can choose to send Test Messages to your email address rather than live messages to your audience. In doing so, a test contact is created in the Hidden Triggered Send Managed List with your test subscriber's Contact Key but with your email address. If you use the Triggered Send Managed List in triggered sends outside of Journey Builder you may see subscribers with your email address on this list. If you don't use the Triggered Send Managed List, you may only notice contacts in your All Contacts that were created from this process with a Type of 3.

This process does not impact Journey Builder sends. The correct All Subscriber's contact and its associated information will be sent to and all personalization will resolve as normal.
