Limited user research

When developing new features, the Fastmail product team may perform outreach to collect early feedback from users. Requests from our product team will be sent from an address ending in @fastmailteam.com (a domain exclusively used by Fastmail staff), and will have a green circle with a white check mark displayed next to the sender's name in our web interface and mobile app.

Early feedback testers are generally pulled from customers who have agreed to receive messages from us regarding testing, or customers who have previously contacted us regarding the particular feature being tested. Limited user research may include Zoom screen sharing, sending static images, asking the user to complete surveys via SurveyMonkey, or directing a user to a temporary test interface at fastmail.dev.

How to send feedback

When using Fastmail beta, you can send feedback anytime by clicking the Send beta feedback button, located at the end of your folder list.

If we are testing a new feature on beta, please click Send beta feedback, then select the feature. This will open a survey where you can provide feedback that goes directly to our product team.

If you encounter bugs or strange behaviors while using beta, please click Send beta feedback. (If we are testing a feature, you will also need to select Something else.) This will open a template for you to fill out, which is then filed as a ticket with our support team.
