What is Invite Acceptance Rate?

Short answer: The percentage of sent invitations that result in the recipient creating an account.

Definition

The percentage of sent invitations that result in the recipient creating an account.

Formula

Invites accepted / Invites sent x 100

How to measure

Track every invite sent through the in-product invite mechanic and divide accepted invites by total invites sent.

Why track it

This rate isolates the quality of the invite mechanic and messaging itself, separate from how many invites get sent in the first place.

Example

A collaboration tool improves invite acceptance from 20% to 38% by redesigning the invite email's preview and call to action.
