Inbox-Placement Testing
Send a real test to your own seed inboxes across providers and track delivery and opens per address. Catch a deliverability problem on a seed list — not on your whole audience.
The worst time to discover a deliverability problem is after you've sent to 50,000 people. Inbox-placement testing moves that discovery earlier: you keep a small list of seed inboxes across the providers your audience uses (Gmail, Outlook, Apple and more), and before a big campaign you send the real email to them. The platform tracks delivery and opens per address, so you see whether your message is landing.
One honest note on scope: fully automated inbox-vs-spam folder detection needs IMAP access to those seed inboxes (an ops integration). Until that's wired for your account, delivery and open tracking are fully automatic and folder placement is recorded manually — you still get the early-warning signal that matters most: is it getting through at all, and are opens healthy per provider. Pair it with the DNS checker and domain warm-up and you send big campaigns with evidence, not hope.
