Reach rate by inbox provider

Definition

Reach rate is the share of an inbox provider's unique recipients (Gmail, Outlook, Yahoo…) who opened at least one message: unique opens divided by unique recipients, for that provider. It is used to spot a deliverability drop at a single provider.

How it is computed, where to read it

The overall open rate drowns that signal: an account can show a decent average while Gmail sends its messages to spam.

Numerator and denominator are both unique: mixing deduplicated opens with non-deduplicated sends means nothing.

KlaviBoard computes this rate per provider from the Inbox Provider properties on Klaviyo events and alerts when it drops more than 5 points versus the previous period, with at least 500 recipients in each period.

The threshold

A drop of more than 5 percentage points at one provider, on at least 500 unique recipients: KlaviBoard alert rule (Studio plans and above).

Spam complaint

A spam complaint is a recipient clicking "report as spam" in their inbox. The complaint rate is complaints divided by sends; it is the lowest and most serious deliverability threshold.

Bounce rate

Bounce rate is the share of sent emails the recipient's server refused: non-existent address (hard bounce) or full inbox and temporary incidents (soft bounce). It is bounces divided by sends.

Bot click

A bot click is an automated click on an email or SMS link, performed by a security system checking the link, not by the recipient. Klaviyo flags it with the Bot Click property on the click event.
