Alerts
Which alerts fire today, how exactly-once delivery works, and why a rank-drop rule can be configured before it can deliver.
Alerts
Alert rules are configured per site and deliver by email, Slack incoming webhook, or an HMAC-signed generic webhook. Deliveries are not metered.
<!-- docs-truth: metric=none; unit=none-deliveries-not-metered; cache-hits=not-applicable; refund=not-applicable; cadence=on-observed-transition; estimates=provider-observation -->What fires today
New and lost referring-domain alerts fire from two consecutive completed link reviews. The alert carries the frozen before-and-after evidence pair that produced it.
Rank-drop rules can be configured and saved, but they deliver from confirmed rank-drop observations that the shipped rank pipeline does not yet produce. Backlink change alerts are the channel that fires today.
One alert per transition
Delivery is exactly-once, keyed to the observed transition rather than to each domain. A review that adds 300 links sends one alert containing a bounded sample of up to 50 domains alongside the honest full count.
A first link review has no baseline to diff against and therefore produces no alert. The delivery log records every attempt as sent, failed, or suppressed.
Channels
Email is available on every paid tier. Slack and the generic webhook are Pro and above. Structural limits allow 0, 2, 10, and 50 alert rules on Free, Starter, Pro, and Agency.
Slack is a user-pasted incoming-webhook URL — there is no RankMeFast Slack app and no bot. Generic webhooks are signed so your receiver can verify the payload came from RankMeFast.
Honest limits
An alert reports an observed change between two stored snapshots. It is not a judgement about link quality and not a prediction of a ranking effect.
If a transport fails, the delivery is recorded as failed rather than retried indefinitely, and the observed transition is never re-sent as a second alert.
