What it does

Shopify Admin Email Deliverability Audit is an agent skill from 40RTY-ai/shopify-admin-skills. Read-only: scans the customer database for malformed emails, role accounts, disposable domains, and bounce-suspect patterns to protect sender reputation.

Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts. Compatibility notes: Claude Code, Cursor, Codex, Gemini CLI

It sits in Backend & APIs, covering Transactional email. It works with Shopify. The repository describes itself as: Community-maintained AI agent skills for operating Shopify stores — workflows, optimization, reports and more. The licence is MIT.

When your agent uses it

  • Tasks that involve Transactional email

Example prompts

  • “/shopify-admin-email-deliverability-audit”

Requirements

  • Compatibility (from SKILL.md): Claude Code, Cursor, Codex, Gemini CLI

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

  1. invalid_syntax — fails RFC 5322 local-part / domain validation, missing @, contains whitespace, double dots, leading/trailing dot
  2. role_account — local part exactly matches a role_localparts entry (case-insensitive)
  3. disposable_domain — domain matches the disposable-domain list (mailinator, guerrillamail, tempmail-style domains, etc.)
  4. plus_alias — contains + in local part (informational; not a deliverability problem on its own, but useful for de-duplication)
  5. bounce_suspect — heuristics: numeric-only local part, length > 64 chars, ALL-CAPS, repeated characters (aaaaa), keyboard rolls (asdfghjk)
  6. duplicate — same normalized email already seen in the customer set

What it can do on your machine

Read from SKILL.md and the folder at commit 6765cb4. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • shopify

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

  • Compatibility

    Claude Code, Cursor, Codex, Gemini CLI

    From compatibility in the SKILL.md frontmatter.

Context cost

Shopify Admin Email Deliverability Audit loads about 1.7k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 538 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.7k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Purpose

Scans the entire customer list and flags addresses that will hurt email deliverability if included in marketing sends: syntactically invalid addresses, role accounts (info@, admin@, sales@), known disposable / temporary domains, and suspected hard-bounce patterns. Output is a suppression list ready to import into your email platform. Read-only — no mutations.

Prerequisites

  • Authenticated Shopify CLI session: shopify store auth --store <domain> --scopes read_customers
  • API scopes: read_customers

Parameters

ParameterTypeRequiredDefaultDescription
storestringyes—Store domain (e.g., mystore.myshopify.com)
marketing_consent_onlyboolnotrueOnly scan customers who currently accept marketing — those are the ones at risk of being mailed
disposable_domainsarraynobuilt-in listOverride built-in disposable-domain list
role_localpartsarrayno["info","admin","sales","support","contact","noreply","help","webmaster","postmaster"]Local-part prefixes to flag as role accounts
formatstringnohumanOutput format: human or json

Safety

ℹ️ Read-only skill — no mutations are executed. Safe to run at any time. No emails are sent, no marketing consent is changed.

Detection Rules

For each customer email, run these checks in order and assign one or more flags:

  1. invalid_syntax — fails RFC 5322 local-part / domain validation, missing @, contains whitespace, double dots, leading/trailing dot
  2. role_account — local part exactly matches a role_localparts entry (case-insensitive)
  3. disposable_domain — domain matches the disposable-domain list (mailinator, guerrillamail, tempmail-style domains, etc.)
  4. plus_alias — contains + in local part (informational; not a deliverability problem on its own, but useful for de-duplication)
  5. bounce_suspect — heuristics: numeric-only local part, length > 64 chars, ALL-CAPS, repeated characters (aaaaa), keyboard rolls (asdfghjk)
  6. duplicate — same normalized email already seen in the customer set

A customer can carry multiple flags; the most severe (invalid_syntax > bounce_suspect > disposable_domain > role_account > plus_alias) drives the recommended action.

Workflow Steps

  1. OPERATION: customers — query Inputs: first: 250, select id, defaultEmailAddress { emailAddress, marketingState }, numberOfOrders, tags, pagination cursor. If marketing_consent_only: true, filter query: "email_marketing_state:subscribed" Expected output: All targeted customers with email; paginate until hasNextPage: false

  2. Run detection rules over each email; collect flags

  3. Aggregate counts per flag, build suppression list

Error Handling

ErrorCauseRecovery
THROTTLEDAPI rate limit exceededWait 2 seconds, retry up to 3 times
Customer with no emailPhone-only / POS accountSkip, do not include in suppression list
Disposable list out of dateNew temp-mail domain not in built-in listCaller can override via disposable_domains parameter
Unicode local partsInternationalized email addressesNormalize via NFC; do not flag valid IDN domains

Best Practices

  • Run before every large promotional send — high invalid / bounce rates above 2% put your sending domain reputation at risk.
  • Treat role_account flags as soft-suppression: those addresses rarely consent to marketing meaningfully and frequently mark mail as spam.
  • Re-audit quarterly even if the customer list is static — domain reputation lists change, and disposable-email providers add new domains.
  • Pair with marketing-consent-report to confirm consent state aligns with what your email service provider has on file.
  • Hand the resulting suppression CSV to your email service provider's import-suppression-list feature; do not silently delete customers from Shopify based on this audit.
