BillionVerifyGoogle Search Console
Detect content decay from Google Search Console and alert via Slack and email
Pull contacts, verify each address with BillionVerify, and continue to Google Search Console — only deliverable addresses get through.
Why verify before the send
Sending to invalid, risky, catch-all, or disposable addresses spikes your bounce rate and erodes sender reputation. A verification gate before the Google Search Console step removes that risk automatically — only deliverable addresses continue, the rest are flagged.
The workflow
BillionVerify — verification sits right before the send.
Node by node
- 1Weekly Monday 8AM TriggerTrigger· n8n
Starts the workflow — on a schedule, a webhook, or manually while you test.
- 2Calculate Date RangesSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 3Fetch GSC Recent 7 DaysSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 4Fetch GSC Previous 28 DaysSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 5Compare Periods and Detect DecaySource· n8n
Provides or transforms the contact data flowing through the workflow.
- 6Filter Only Decaying PagesLogic· n8n
Routes items based on the workflow logic.
- 7Log All Results to Decay SheetSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 8Build Weekly Decay ReportSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 9Check If Any Critical PagesLogic· n8n
Routes items based on the workflow logic.
- 10Post Report to SlackSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 11Verify Email (BillionVerify)Verify· billionverify
The BillionVerify node verifies the address — status (valid / invalid / risky / catch-all / role / disposable), is_deliverable, and a confidence score — before anything is sent.
- 12Generate Fix Tasks for Critical PagesSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 13IF deliverableLogic· n8n
Branches on the verification result: only deliverable addresses continue to the send; the rest are skipped and flagged.
- 14Log Fix Tasks to SheetSource· n8n
Provides or transforms the contact data flowing through the workflow.
- 15Email Weekly ReportSend· n8n
Sends only to verified, deliverable addresses. Swap in your own provider node if you send elsewhere.

Set **n8n environment variable** `GSC_SITE_URL` to your site (e.g., `https://yoursite.com`)\n2. Set **n8n environment variable** `DECAY_SHEET_URL` to your Google Sheet URL\n3. Create a Google Sheet with two tabs:\n - `Decay Log` — headers: `date`, `page_path`, `signal`, `clicks_now`, `clicks_before`, `click_change_pct`, `position_now`, `position_before`, `position_change`, `impressions_now`, `impression_change_pct`, `ctr_now`\n - `Fix Tasks` — headers: `created`, `priority`, `page_path`, `page_url`, `signal`, `click_change_pct`, `position_change`, `recommended_action`\n4. Connect **Google Search Console OAuth2** credentials\n5. Connect **Google Sheets OAuth2** credentials\n6. Connect **Slack OAuth2** credentials and set target channel\n7. Configure **SMTP / email** credentials and update recipient address\n\n## Customization\n- Adjust decay thresholds in the \"Compare Periods and Detect Decay\" node\n- Change schedule frequency (daily, bi-weekly, monthly)\n- Add more notification channels (Telegram, Discord, etc.)\n- Extend fix task logic with AI-powered content refresh suggestions"

FAQ
Why verify before sending in Google Search Console?
Verifying first keeps your bounce rate low, which protects your sender reputation and your results.
How do I import this workflow?
Download the JSON, then in n8n go to Workflows → Import from File (or paste it). Install the BillionVerify community node and add your API key credential.
What happens to risky or catch-all addresses?
They are routed to the false branch and excluded from the send. You decide whether to retry, review, or drop them.
