Automated Brevo Subscriber List Reconciliation
Every Monday, WebRun opens Brevo, exports the current subscriber and unsubscribe list, reconciles it against the master contact sheet stored in Google Drive, flags any contacts missing from one side or the other, and posts the reconciliation summary to Slack.

WebRun reconciles your Brevo subscriber and unsubscribe list against the master contact sheet in Google Drive every Monday, flags any contact missing from one side or the other, and posts the summary to Slack, so your marketing ops team catches list drift weekly instead of discovering it during a campaign send.

Every action is checked against this policy before it runs.
Questions, answered
Will it delete or add contacts automatically?
No. WebRun only flags mismatches for review. Adding, merging, or deleting a contact is always a decision a human makes.
What counts as a mismatch?
Any contact that appears in Brevo but not on the master sheet, or the other way around, including any Brevo unsubscribe not yet reflected on the sheet.
How often does it run?
Every Monday morning, so mismatches are caught weekly before they pile up into a bigger cleanup job.
