Is Streak Mail Merge for Gmail safe?

Clean risk

Streak Mail Merge for Gmail identifies signed-in Gmail users to Userflow with profile and plan attributes.

When Gmail loads and a Streak user is signed in, the extension initializes Userflow and calls identify with the user's key, name, email, signup date, active experiments, trial eligibility, plan details, and client version. The stored claim identifies Userflow's event endpoint as e.userflow.com.

Shared hosts - 2 hostnames

Hostnames hardcoded in this extension that few other listings call. That can mean one operator behind both, and it can equally mean a small shared vendor, so it is context rather than a conclusion. Hosts that many listings call are left out: they are services, not connections.
