What it does

Email Sequence is an agent skill from indranilbanerjee/digital-marketing-pro. Design an ESP-ready email sequence: subjects, copy, timing, branching, deliverability. "build a welcome sequence"

Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `sequence-blueprint.md`).

It sits in Marketing & SEO, covering Email marketing and Transactional email. The repository describes itself as: An open-source AI marketing operating system for strategy, SEO, AEO/GEO, paid media, content, CRM, and analytics - grounded in brand context, human approval, and verifiable… The licence is MIT.

When your agent uses it

  • Tasks that involve Email marketing
  • Tasks that involve Transactional email

Example prompts

  • “build a welcome sequence”
  • “/email-sequence”

Workflow steps

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

  1. Load brand context: Read ~/.claude-marketing/brands/_active-brand.json for the active slug, then load…
  2. Map the sequence to the customer journey stage and define the narrative arc
  3. Determine optimal email count and send cadence based on sequence type
  4. Write each email: subject line (2-3 options), preview text, body copy with clear CTA
  5. Define segmentation and branching logic (open/click triggers, conditional paths)
  6. Apply deliverability checks: spam trigger words, link density, image-to-text ratio, authentication reminders, and the bulk-sender…
  7. Add personalization tokens and dynamic content recommendations
  8. Review full sequence for brand voice consistency and regulatory compliance (CAN-SPAM, GDPR)

What it can do on your machine

Read from SKILL.md and the folder at commit 9e949f3. 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

Email Sequence loads about 1.2k tokens when it runs. Until then it costs about 32 tokens; SKILL.md has 540 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~32
When it runs · the whole SKILL.md, loaded when a task matches
~1.2k

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.

Design an ESP-ready email sequence: subjects, copy, timing, branching, deliverability. "build a welcome sequence"
argument-hint
[sequence-type]

/digital-marketing-pro:email-sequence

Purpose

Design a full email sequence ready for implementation in any ESP. Includes subject lines, preview text, body copy, send timing, segmentation rules, and deliverability best practices.

Input Required

The user must provide (or will be prompted for):

  • Sequence type: Welcome, nurture, onboarding, re-engagement, cart abandonment, post-purchase, event, promotional
  • Goal: What the sequence should achieve (activate, convert, retain, upsell, educate)
  • Audience segment: Who receives this sequence and entry trigger
  • Number of emails: Desired count or let the system recommend
  • Key messages/offers: Core value props, promotions, or content to include
  • Existing ESP: Platform in use (Klaviyo, Mailchimp, HubSpot, etc.) for format guidance

Process

  1. Load brand context: Read ~/.claude-marketing/brands/_active-brand.json for the active slug, then load ~/.claude-marketing/brands/{slug}/profile.json. Apply brand voice, compliance rules for target markets (skills/context-engine/compliance-rules.md), and industry context. Also check for guidelines at ~/.claude-marketing/brands/{slug}/guidelines/_manifest.json — if present, load restrictions and relevant category files. Check for custom templates at ~/.claude-marketing/brands/{slug}/templates/. Check for agency SOPs at ~/.claude-marketing/sops/. If no brand exists, ask: "Set up a brand first (/digital-marketing-pro:brand-setup)?" — or proceed with defaults.
  2. Map the sequence to the customer journey stage and define the narrative arc
  3. Determine optimal email count and send cadence based on sequence type
  4. Write each email: subject line (2-3 options), preview text, body copy with clear CTA
  5. Define segmentation and branching logic (open/click triggers, conditional paths)
  6. Apply deliverability checks: spam trigger words, link density, image-to-text ratio, authentication reminders, and the bulk-sender checklist below
  7. Add personalization tokens and dynamic content recommendations
  8. Review full sequence for brand voice consistency and regulatory compliance (CAN-SPAM, GDPR)

Bulk-sender deliverability checklist (Gmail / Yahoo / Outlook)

Any brand sending at bulk volume (~5,000+ messages/day to a mailbox provider) must meet the mailbox-provider sender requirements or mail is throttled or rejected. Bake these into the sequence's implementation notes (ported from /digital-marketing-pro:send-email-campaign, with Outlook 2025 added):

  • Authenticate the sending domain: SPF and DKIM and a published DMARC policy (at least p=none, aligned) — required by Gmail & Yahoo (Feb 2024) and Microsoft Outlook / Outlook.com (rolling out through 2025 for senders ≥5,000/day).
  • One-click unsubscribe: include the List-Unsubscribe header with one-click support (RFC 8058), and honour opt-outs within 2 days. A visible unsubscribe link in the body is still required in addition.
  • Keep the spam-complaint rate under 0.3% (measured in Google Postmaster Tools / Yahoo / Microsoft SNDS) — ideally under 0.1%.
  • Send from a consistent, PTR/reverse-DNS-valid IP over TLS, with a warmed-up sending domain and consistent from-address.
  • Physical mailing address + accurate From/Reply-To identity in every message (CAN-SPAM), and documented opt-in consent per jurisdiction (GDPR / CASL).
  • List hygiene: suppress hard bounces and inactive addresses; never send to purchased lists.

For per-type email counts and cadence, the per-email blueprint, branching/exit/suppression rules, the per-email deliverability checklist, the deliverable layout, and the after-sequence follow-up menu, read sequence-blueprint.md beside this file.

Output

A complete email sequence containing:

  • Sequence overview with goals, audience, and trigger conditions
  • Per-email breakdown: subject lines, preview text, body copy, CTA, send timing
  • Segmentation and branching logic diagram
  • Deliverability checklist per email
  • Personalization and dynamic content recommendations
  • Compliance checklist (unsubscribe, physical address, consent)
  • Performance benchmarks to measure against

Agents Used

  • content-creator — Email copy, subject lines, narrative arc, CTA strategy
  • brand-guardian — Voice consistency, compliance review, regulatory checks
  • email-specialist — Deliverability optimization, send timing strategy, subject line scoring, spam risk analysis, A/B test design
