Yes, GlockApps supports smart tests that allow to test messages via a single dedicated email address.
To use smart tests, you need to connect your mailbox with GlockApps, generate a proxy email address, and send the message to the proxy address. GlockApps will do the rest for you: create a test and re-send the message to the seed list via your email account. The test will be created under Reports > Smart Tests in the Inbox Insight tool. This mode eliminates the need to create a test manually and copy-paste the id in the message.
