AI Email Automation for Agencies
AI drafts, code checks, you approve in Slack, then it sends and follows up automatically.
⚡ Instant delivery after payment · 🔒 Cashfree UPI, cards & netbanking
Agency outbound has a quality-versus-volume conflict. Manual personalization does not scale, and autonomous AI sending risks hallucinated claims, damaged domains, and accidental sends. AI Email Automation for Agencies resolves it by keeping AI in the drafting seat and a human in the send seat. A lead arrives by webhook, the workflow normalizes it, writes a subject, preview, body, and two follow-ups, then enforces hard guardrails: no links, no calendar links, no spam phrases, strict length limits. You approve in Slack with a scoped token, Gmail sends, and follow-ups fire on day 4 and day 9. Every failure goes to Slack and a Postgres dead-letter table.
A three-workflow n8n system that drafts personalized agency outbound, enforces deterministic guardrails, and sends only after a human clicks a scoped Slack approval link.
Agency founders, growth leads, and operations teams running founder-led outbound on Gmail or Google Workspace, Slack, and Postgres.
AI drafting plus code-level guardrails, 7-day Slack approval tokens, day-4 and day-9 follow-ups, and Postgres dead-letter recovery with error alerts.
3 production workflows, zero autonomous sends, 10 enforced guardrail rules, and every failure logged and surfaced in Slack.

|---|---|
| ✕ A junior spending 34 minutes per lead on research, writing, QA, and tracking. | ✓ AI drafts in seconds, code checks every rule, and the human only makes the judgment call. |
| ✕ An autonomous AI tool sending a hallucinated claim before anyone reads it. | ✓ A mandatory Slack approval token and a status check that blocks unapproved sends. |
| ✕ Follow-ups living in a spreadsheet and failures disappearing into a silent void. | ✓ Scheduled day-4 and day-9 follow-ups with Slack alerts and Postgres dead-letter recovery. |

How to use this skill (Step-by-step)
Run offline in your local workspace, orchestrate through any agent (Claude Code, Cursor, Antigravity, Cline), or plug directly into CI/CD pipelines.
Start the Self-Hosted Stack
Launch Postgres, Redis, and n8n with the included Docker Compose file.
cp .env.example .env && docker compose up -dCreate the Database Tables
Apply the included schema for drafts and dead letters.
docker compose exec -T postgres psql -U "$POSTGRES_USER" -d "$POSTGRES_DB" < schema.sqlImport and Bind Workflows
Import the three workflow JSON files and bind OpenAI, Gmail, Slack, and Postgres credentials.
open http://localhost:5678Run the Sample Lead
Fire the included test payload and verify drafting, approval, and follow-up scheduling end to end.

Questions
Does it send email automatically?
No. It sends only after a human clicks Approve in Slack with a valid, unexpired token. Without that approval, nothing leaves the system.
Do I need an n8n subscription?
No. The included Docker Compose stack runs n8n, Postgres, and Redis locally or on your own server with zero platform fees. A cloud n8n instance also works.
Can I use this for client deployments?
Yes. The commercial license permits client implementations and managed-service deployments. Reselling the raw package is prohibited.
What happens when a workflow fails?
The error workflow posts a Slack alert and writes a dead-letter row to Postgres so no lead disappears silently.
Is the ₹2,999 price GST inclusive?
Yes. The displayed price is GST-inclusive for Indian buyers, with UPI, cards, RuPay, and netbanking available at checkout.
