 > [!NOTE]
 > The test suite also uses these environment variables to run some tests:
 >
-> - `MAILSAC_API_KEY`: Used for [Mailsac](https://mailsac.com/) to retrieve email codes and magic links from temporary email addresses.
 > - `VERCEL_PROJECT_ID`: Only required if you plan on running deployment tests locally. This is the Vercel project ID, and it points to an application created via the Vercel dashboard. The easiest way to get access to it is by linking a local app to the Vercel project using the Vercel CLI, and then copying the values from the `.vercel` directory.
 > - `VERCEL_ORG_ID`: The organization that owns the Vercel project. See above for more details.
 > - `VERCEL_TOKEN`: A personal access token. This corresponds to a real user running the deployment command. Attention: Be extra careful with this token as it can't be scoped to a single Vercel project, meaning that the token has access to every project in the account it belongs to.
