What it does

Deliverability Ops is an agent skill from gtmagents/gtm-agents. Use when investigating inbox placement, reputation, and compliance signals across senders.

Its SKILL.md is about 390 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Backend & APIs, covering Transactional email and Email management. The repository describes itself as: Production-ready collection of GTM agents and specialized skills for claude code. Covers sales, marketing, customer success, and revenue operations workflows. The licence is Apache-2.0.

When your agent uses it

  • Investigating inbox placement
  • Compliance signals across senders

Example prompts

  • “/deliverability-ops”

Workflow steps

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

  1. Engagement – opens, clicks, unsubscribes, spam complaints by ISP.
  2. Reputation – Google Postmaster, Microsoft SNDS, Talos/Barracuda, Spamhaus, Validity.
  3. Infrastructure – SPF/DKIM/DMARC alignment, BIMI, TLS, reverse DNS, dedicated vs shared IP.
  4. List Health – bounce types, spam traps, opt-in provenance, inactivity thresholds.

What it can do on your machine

Read from SKILL.md and the folder at commit 78e0419. 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

    No scripts in the folder and no shell commands in SKILL.md.

    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.

Context cost

Deliverability Ops loads about 385 tokens when it runs. Until then it costs about 27 tokens; SKILL.md has 166 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~27
When it runs · the whole SKILL.md, loaded when a task matches
~385

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.

Deliverability Operations Skill

When to Use

  • Inbox placement drops or spam-folder complaints.
  • Preparing for IP/domain warmups or volume ramps.
  • Auditing authentication, feedback loops, or compliance settings.

Framework

Signals to Monitor
  1. Engagement – opens, clicks, unsubscribes, spam complaints by ISP.
  2. Reputation – Google Postmaster, Microsoft SNDS, Talos/Barracuda, Spamhaus, Validity.
  3. Infrastructure – SPF/DKIM/DMARC alignment, BIMI, TLS, reverse DNS, dedicated vs shared IP.
  4. List Health – bounce types, spam traps, opt-in provenance, inactivity thresholds.
Playbook Steps
  1. Snapshot key metrics over last 7/30 days.
  2. Identify affected mailbox providers (Gmail, Outlook, Yahoo, etc.).
  3. Validate authentication + sending domains.
  4. Segment audiences by engagement tier; limit sends to VIP/high intent.
  5. Recommend remediation actions (warmup plan, content refresh, list cleaning, cadence adjustment).

Templates

  • Deliverability diagnostic worksheet (reputation + infrastructure + content).
  • IP/domain warmup tracker (volume ramp table).
  • Compliance checklist (CAN-SPAM, CASL, GDPR/CCPA, unsubscribe handling).

Tips

  • Pair with segmentation skill to isolate healthy cohorts.
  • Document every remediation change to correlate with future reputation shifts.
  • Align marketing, security, and legal teams on consent language.
