⚙️ Pause risky Instantly sending accounts with Slack alerts and Google Sheets logs
⚡ 0 views · ⚙️ DevOps & CI/CD
Description
Quick overview
This workflow runs every morning to check Instantly sending accounts for deliverability risk using warmup analytics, DNS vitals, and recent bounce stats, then auto-pauses risky accounts and posts alerts and a daily digest to Slack while logging account health history to Google Sheets.
How it works
- Runs every morning on a schedule.
- Retrieves all sending accounts from the Instantly API and batches them for bulk checks.
- Pulls warmup health analytics, DNS vitals (MX/SPF/DKIM/DMARC), and daily sent/bounced stats from Instantly for the configured lookback window.
- Scores each account against the configured thresholds to label it healthy, watch, pause recommended, or already paused.
- Pauses active accounts in Instantly when auto-pause is enabled and the account crosses a pause threshold, then sends a Slack alert with the reason.
- Sends a daily Slack digest summarizing overall account health and appends one row per account to a Google Sheets “Health log” tab for trend tracking.
Setup
- Create an Instantly API key with API v2 access and add it to n8n as an HTTP Bearer Auth credential used by the Instantly HTTP Request steps.
- Add a Slack credential and set the target channel name in the thresholds (for example, #deliverability).
- Add a Google Sheets credential, create a spreadsheet with a sheet tab named “Health log”, and replace the tracker Google Sheets URL with your document URL.
- Review and adjust the thresholds (bounce rate limits, lookback days, warmup score limits, batch size, and autoPause/pauseOnDnsFailure toggles) before activating the workflow.
Requirements
- Instantly account with an API v2 key (accounts read and update scopes)
- Bearer Auth credential in n8n for the Instantly API key
- Slack workspace
- Google Sheets with a tab named Health log (optional)
Customization
- Change maxBounceRatePct (default 3%) or minSentForBounceCheck in Set Bounce Alert Thresholds
- Adjust warnBelowWarmupScore and pauseBelowWarmupScore to fit your warmup standards
- Set pauseOnDnsFailure to true to pause accounts whose domain fails SPF, DKIM or DMARC
- Set notifyWhenAllHealthy to false to only get Slack messages when something is wrong
- Change the schedule to run before each sending window
- Delete the Google Sheets nodes if you don’t need a history log
Additional info
Run it once with autoPause set to false to review the verdicts before letting it pause anything. Paused accounts are never resumed automatically: fix the cause, then resume them in Instantly. The Instantly API is called through HTTP Request nodes with a Bearer Auth credential, so no API key is stored in the workflow.
