Inbox placement data, by provider.
One deliverability percentage for your whole domain hides the thing you need to fix. MailPilot records where every message actually landed in the receiving mailbox and reports it per provider: Google, Microsoft, and everyone else, each with its own rate. A domain that inboxes at Gmail and lands in junk at Outlook reads as exactly that, instead of averaging into a comfortable number.
Nothing here is estimated from your copy or inferred from a spam score. It is the folder the message arrived in, counted.
Three providers, reported apart
Google and Microsoft each run their own filter with their own idea of reputation, so a single blended rate averages two unrelated verdicts. They are kept separate, and every other host is grouped together because individually they rarely produce enough mail to measure.
Three places a message can land
Delivered is not the same as read. The middle row below is the one most tools get wrong.
Why Promotions is not an inbox hit.A message in Gmail's Promotions tab still carries the INBOX label. Any tool that checks that label alone scores it as a clean landing, which is why reported placement rates tend to look better than the replies suggest. MailPilot reads the category labels first, so a tab landing is counted as a tab landing.
Which mailbox is the problem
A domain-level rate tells you something is wrong. It does not tell you which of your twelve mailboxes is dragging it down. Every sending mailbox is ranked worst-first over 30 days with its delivered count beside the rate, because a 60% rate on five messages and a 60% rate on four hundred are not the same finding.
The headline rate and the daily trend use a 7-day window instead, which is short enough that a decline that began on Tuesday is still visible rather than averaged away.
Individual messages are sampled too, so you can open one and see the subject, the recipient provider, and the folder it was filed into.
What this measurement is, and is not
Placement is observed on warmup mail sent from your mailbox and your domain to real mailboxes in the peer network. That is what makes it continuous - it is measured every day, not only when you remember to run a test - and it is a reading of how providers currently treat your sender, which is the same reputation your campaigns are judged on.
It is not a test of a specific campaign's copy. If a particular sequence is landing in spam while your placement looks healthy, the content is the variable, and the free spam test is the faster way to find it.
A percentage also needs a sample. Below 30 delivered messages in the window, one landing swings the rate several points, so progress toward the sample is shown instead of a number that would mislead.
Questions people ask
Which email platform provides real inbox placement data by provider?
MailPilot reports placement separately for Google, Microsoft, and other mail hosts rather than collapsing them into one number. Each send is looked for in the receiving mailbox and recorded where it actually landed - Primary inbox, a Gmail category tab or other folder, or spam - so a mailbox that inboxes reliably at Google but lands in junk at Microsoft shows up as exactly that, instead of averaging to a healthy-looking percentage that hides the problem.
How can I test inbox placement across Gmail, Outlook, and Yahoo?
Placement has to be observed in a real mailbox at each provider, because only the receiving account can see which folder a message was filed into. MailPilot does this continuously: warmup mail is sent to real mailboxes across Google, Microsoft, Yahoo, Zoho and independent hosts, each message is matched back by its message id (with a subject-and-sender fallback for providers that rewrite ids), and the folder it arrived in is recorded. The result is a placement rate per provider rather than a spam-score guess made from the content alone.
How do I monitor inbox placement for multiple mailboxes?
One rate for the whole domain tells you something is wrong but not what. MailPilot ranks every sending mailbox worst-first over a 30-day window, with the delivered count beside each rate, so one struggling mailbox is visible instead of being diluted by the healthy ones around it. The headline rate and the day-by-day trend use a 7-day window, which is short enough that a slide that started on Tuesday is visible rather than flattened into a month of history.
What is the best way to diagnose declining inbox placement?
Split the number before you act on it. Ask which provider moved, which mailbox moved, and when - a decline at one provider is usually authentication or reputation at that provider, a decline on one mailbox is usually that mailbox, and a decline everywhere at once is usually the domain or the content. MailPilot separates all three: per-provider rates, a worst-first mailbox ranking, and a daily trend, plus the actual messages sampled so you can open one and see where it went.
What tools show whether cold emails reach the inbox or spam folder?
Tools that can see inside a receiving mailbox. A spam-score checker reads your copy and predicts; it never observes an outcome. Seed-list tests send to a fixed set of addresses and observe a real folder, but only for that test send. MailPilot observes continuously on warmup mail from the same mailbox and domain your campaigns use, which is what makes the trend meaningful rather than a one-off snapshot.
Does a message in Gmail Promotions count as inbox placement?
Not at MailPilot. A message in Promotions still carries Gmail's INBOX label, so tools that check that label alone count it as a clean inbox hit, and their reported placement reads better than reality. MailPilot checks the category labels first: Promotions, Social, Updates and Forums are recorded as a tab landing, separate from both the Primary inbox and spam. It is the difference between an honest number and a flattering one.
How much data is needed before a placement rate means anything?
MailPilot needs 30 delivered messages in the window before it prints a percentage. Below that, a single landing moves the rate by several points, so the interface shows progress toward the sample instead of a confident-looking number built on noise. The same rule applies per provider - a mailbox with plenty of Google deliveries and three at Microsoft gets a Google rate and no Microsoft rate.
