Seed inbox tests show where emails land in the addresses tested. They’re a useful signal, not a guarantee for every recipient. And yes—Gmail Promotions is still the inbox.

A FEW GOOD QUESTIONS
Glad you asked.
A little more about the idea
and where we’re headed.
Is InboxSignal ready to use?
InboxSignal is an early-stage concept. This page is an invitation to help shape a pilot; the report and workflow shown here are illustrative. Joining the interest list does not create an account or start inbox testing. We’ll contact you about availability.
How would inbox placement testing work?
The proposed workflow uses controlled test addresses, often called seed inboxes. You would send a representative email through your usual sending setup, and the check would observe where it arrives. We’re validating scheduling, provider coverage, and reporting with pilot participants.
Does a good result guarantee every recipient gets my email?
No. Seed inbox results are directional signals from the addresses tested. Individual inbox placement can vary with recipient engagement, filtering, reputation, and other factors. A seed test cannot guarantee delivery to every real recipient.
Is Gmail’s Promotions tab the same as spam?
No. Promotions is a category inside the Gmail inbox. Our sample report counts Promotions as inbox placement and treats spam separately. That distinction is part of the reporting we want to build.
Which email tools and providers will be supported?
We’re still validating the first set of integrations and providers. Gmail, Outlook, and Yahoo on this page demonstrate the proposed reporting format; they do not indicate that integrations are live. Tell us about your current workflow when you join.
What will it cost?
Pricing has not been set. We’re speaking with marketing teams and agencies to understand the value, expected check frequency, and scope of a useful pilot. Joining the interest list is free, and this page takes no payment.
