A JMC cold email is four jobs in under 90 words: a verbatim public signal, the pain that signal implies, a 22-word EVP, and a binary ask.

Grade B

Minor issues only, no Medium or High. Worth a quick look at the findings below before installing.

Graded by PlugVetRubric v2

Not a guarantee. A hygiene check of the source at the commit shown, not a security audit.

SECRETS_PATH_DOTENV PERMISSION_SHELL_DECLARED

Why this grade

  • SECRETS_PATH_DOTENV Low

    Mentions a .env file.

    .gitignore, line 6 .env

  • PERMISSION_SHELL_DECLARED Note

    Runs shell commands, and the manifest or description says so.

    scripts/check_deliverability.py, line 94 result = subprocess.run(

Any High, or two or more Medium findings, give D. One Medium gives C. Low findings or a security Note give B. Each code names a finding behind the letter.

Grades are a hygiene check of the source at the commit shown, on the date checked, not a security audit or a guarantee. The free directory grades are automated. Before release, a PlugVet engineer reviews every paid report and any grade we hold back, including all F grades, against the source code and the evidence we quote.
