Settings About whoosin ↗

Connect your Gmail

whoosin reads the replies to invites you sent and keeps the who’s-in list — in your browser, never storing your messages.

You’ll see a Google “unverified app” screen — expected during beta. Click Advanced → Go to whoosin.app to continue.

You sign in on Google's own page — whoosin never sees your password. Google asks you to approve two permissions:

View your email messages and settings Reads only the replies to events you organize, right in your browser, to build your list.
Manage drafts and send emails Google's label for the drafts permission. whoosin only ever writes a follow-up draft — it never sends, and you always press Send.

whoosin can't delete or change your email. Reply snippets go to our AI for a moment to read yes / no / maybe, then they're discarded — never stored, logged, or used for ads. Disconnect anytime from your Google account.

Outlook support is on the roadmap — leave your email and we'll let you know.

Gmail needs a quick reconnect — your browser may have blocked the popup.

Confirm before tracking

whoosin reads every reply against this question — make sure it’s right. Then set the event date (or the deadline to respond by); blank keeps it 30 days.

What are people answering? Track headcount How are answers labeled? whoosin guesses from your email Event or due date

Create an event

whoosin writes the invite as a draft in your Gmail — you review and send it yourself. Replies build your who’s-in list automatically.

Subject Send to optional — easiest is adding people from your contacts in Gmail before you send What are you asking? goes in the email; replies are read against it Track headcount asks for guest counts, tallies a total How are answers labeled? Event or due date optional — keeps the list through the event

Quick setup

Two things before you start — both prefilled, just confirm.

Time zone required — times your reminder emails; change it in Settings anytime

Reminder emails about your own events are on — every one has a one-click unsubscribe, and you can tune or turn them off in Settings.

Quick question

Thanks — that helps us improve. You can paste the original reply for our review (optional). We store it only to improve accuracy, and it’s deleted with your account.
