The 30-day strip
Above the campaign list, PULSE shows the last 30 days of campaign mail: bounces, complaints, and unsubscribes, each as a rate judged against Gmail's guidance and against your own breaker limits. With too few messages to judge, it says so rather than showing a misleading percentage. These rates are worked out from PULSE's own logs — an inference, not the provider's view.
Gmail's own view: Postmaster Tools
Google Postmaster Tools is the one place Gmail states its own verdict on a domain. Connecting it needs three things only a person can do, and the order matters.
- At postmaster.google.com, add each domain you send from (the exact domain in the From address — acme.com and mail.acme.com are separate entries) and complete Google's DNS verification.
- In the Google Cloud project behind your Google integration, enable the Gmail Postmaster Tools API, and make sure the OAuth client's authorized redirect URIs include the address shown on Settings → Integrations → Google (the Postmaster callback is one of three).
- Settings → Email → Gmail's view of your domains → Connect Google Postmaster Tools, signing in as the same Google account that verified the domains. The API has no service accounts; access follows that person.
Once connected, each sending domain shows Gmail's sender-requirements verdict — met, or needs work on specific items such as a DMARC policy or one-click unsubscribe — and, once the domain sends enough mail to Gmail, its daily spam rate and SPF / DKIM / DMARC pass rates. Google publishes a day only above a volume threshold and one to two days late, so "no data published yet" means Gmail has not judged the domain, not that there are no problems. Pull now refreshes on demand; a nightly pull runs anyway.
If the card says the connection needs different permissions, Google has changed its API since you connected: Disconnect, then Connect again.
Test inbox placement before a real send
On any campaign draft, Test inbox placement sends the real message — real subject, real headers, real footer — to the workspace's own connected mailboxes and then looks in each one to report where it was filed: Inbox, Promotions, or Spam. A few seeds are a sample, not a promise, and a mailbox that reads your mail daily is friendlier than a stranger's — but a seed in spam is a warning worth taking before the send. Seeds are any Gmail or Outlook mailbox connected under Settings → Integrations (the shared inbox) or Settings → Personal → Email (your own).
