Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 3 of 3 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
The registry does not list a required key, though some servers ask you to sign in on first use.
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.

Add only the URL. Do not add an Authorization header or an API key to the client config: the server signs you in with OAuth, and the login page asks for your Mailshake credentials.
Step-by-step setup, where to find your credentials, and FAQ: https://usefulapi.io/mailshake/
On first connect you provide your Mailshake API key, created in Mailshake under Extensions → API. The server validates it and stores it per user. No keys go in config files.
