Inbox placement in practice
Your sending tool can tell you an email was delivered. It cannot tell you where it landed. Inbox placement tests send to a panel of seed addresses across Gmail, Outlook and other providers, then check which folder each one reached.
Seed tests are a sample, not the truth for your actual recipients, because real placement also depends on how each recipient has engaged with you. Use them to catch a broken domain early, and watch reply rate by mailbox as the real world check.
