Comet to unsubscribe from selected Gmail messages
Roger Wong tested whether Perplexity Comet could unsubscribe from newsletters directly inside his existing Gmail session. He selected three messages and asked the browser assistant to unsubscribe from the checked emails. Comet then took control of the page, opened the first message and followed its unsubscribe link before moving through the remaining selections.

Two of three selected subscriptions were removed; the remaining form attempt failed, and the author says manual work would have been quicker.
Reported by Roger WongHow the agent did it
- Select the unwanted messages in the existing Gmail session.
- Ask Comet to follow each unsubscribe route from the selection.
- Check which subscriptions actually succeeded and finish failed forms separately.
Where a person stepped in
Wong watched the approximately two-minute run and could stop it; one email-address form failed.
Roger Wong tested whether Perplexity Comet could unsubscribe from newsletters directly inside his existing Gmail session. He selected three messages and asked the browser assistant to unsubscribe from the checked emails. Comet then took control of the page, opened the first message and followed its unsubscribe link before moving through the remaining selections.
The test encountered a useful state-management problem. Gmail no longer retained the checked-message state after an individual email was opened. Comet remembered the three subject lines and used them to continue the work rather than abandoning the task when the visible selection disappeared.
Two unsubscribe attempts succeeded. The second message led to a form where the agent had difficulty entering the correct email address, so that attempt failed. The account gives no evidence that this third subscription was later removed.
Wong watched the browser work for about two minutes. A teal border indicated agent control, and a stop button was available throughout. He explicitly says doing the three clicks manually would have been quicker in this small test. The concrete lesson is therefore the ability to carry a selection across changing page state, together with a form-filling limit. It is a partly successful browser delegation, with an observed result for each selected message.
