How to work out how many people to invite to interviews
A six step method for sizing an interview recruitment email
A six step method for founders, product managers and researchers who need a set number of interviews from an email list. It works backwards from the interviews you need to the number of invitations, using a planning rate for the list, then replaces that assumption with real numbers from a small first batch. Koji shows each step of the funnel per person, so the re-planning step uses your own data.
Where this appears
What's in this process
- Set the number of interviews: Decide how many completed interviews you need before you pick a list.
- Pick the list: Active users, recent signups, churned customers or cold contacts.
- Use a planning rate: The share of that list likely to finish an interview after one reminder.
- Divide and round up: Interviews needed divided by the planning rate is how many to invite.
- Send a small first batch: Email part of the list, add one reminder, and wait a few days.
- Re-plan from your own funnel: Find the step where people drop out, fix it, then size the next batch.
