# Sequencing Toolkit

## Overview

Sequencing platforms send your cold emails — but only if configured correctly.
The mistake: importing a list, writing one template, hitting send, and
wondering why deliverability is 40%. This skill is the **cross-platform router**:
platform selection, sequence architecture, and shared best practices.

For platform-specific setup, load the sibling skills under `tools/`:
`instantly-sequences`, `smartlead-workflows`, `lemlist-setup`, `salesloft-cadences`,
`outreach-sequences`, `hubspot-sequences`.

## Authoritative Foundations

- **Smartlead — Unlimited mailboxes, auto-rotation, AI reply categorization** — Unlimited mailboxes, master inbox, and agency-scale cold email ops.
- **Instantly — Warmup pool, campaign optimization, unified inbox** — Mailbox rotation, campaign caps, and deliverability-first sending setup.
- **Salesloft — Rhythm cadences, Conversations, multi-channel orchestration** — Cadence + coaching rhythm; rhythm-based pipeline management.
- **Outreach — Enterprise sequencing, triggers, analytics** — Sequence governance, task-based selling, and CRM-locked cadences.
- **Lemlist — Personalized images/video, multi-channel sequences** — Multichannel sequences — email, LinkedIn, calls in one enrollment.

## When to Use

Trigger phrases: "sequencing platform setup", "Smartlead configuration",
"Instantly optimization", "Salesloft cadences", "Outreach setup",
"Lemlist sequences", "sequence optimization"

Comparison: `references/platform-comparison.md` · Sequence template: `templates/sequence-architecture.md`

## Platform Selection

| Platform | Best For | Key Features | Cost |
|---|---|---|---|
| **Smartlead** | High-volume, multi-mailbox | Unlimited mailboxes, auto-rotation, master inbox | $89-249/mo |
| **Instantly** | Warmup-first, agencies | Largest warmup pool, campaign optimization | $37-97/mo |
| **Salesloft** | Enterprise, multi-channel | Rhythm cadences, Conversation intelligence | $125-165/seat |
| **Outreach** | Enterprise, complex workflows | Sequencing engine, triggers, analytics | $100-160/seat |
| **Lemlist** | Personalized outreach, SMB | AI images/video, multi-channel | $59-99/mo |

## Artifacts

### Standard Sequence Architecture (All Platforms)
```
Email 1 (Day 0): Introduction — problem-focused, 50-75 words
Email 2 (Day 3): Value add — case study or insight, 75-100 words
Email 3 (Day 7): Social proof — customer result, 50-75 words
Email 4 (Day 12): "Breaking up" — last attempt, direct ask
LinkedIn touch (Day 2): Connect request or DM
Call (Day 5): Short voicemail if no answer

Total: 4 emails + 2 multi-channel touches over 14 days
```

### Mailbox Configuration (Smartlead/Instantly)
```
Per domain: 3 mailboxes max. 30 emails/day per mailbox.
3 domains × 3 mailboxes = 9 mailboxes. 9 × 30 = 270 emails/day capacity.
Warmup: 2 weeks minimum before full volume. Start at 5/day. Increment 5/day.
Rotation: Auto-rotate between mailboxes. Randomize send times.
```

## Implementation Checklist

- [ ] Mailboxes warmed up (2+ weeks) before full volume
- [ ] SPF/DKIM/DMARC configured for all sending domains
- [ ] Custom tracking domain set up (not shared)
- [ ] A/B test running (subject lines + copy variants)
- [ ] Reply handling: AI auto-categorization + human escalation rules
- [ ] Bounce rate under 3% (investigate if higher)
- [ ] Daily send limits per mailbox respected

## Common Pitfalls

1. **No warmup.** New mailbox sends 50 emails/day day 1. Spam folder. Burned domain.
   Fix: 2-week warmup. Start at 5/day. Increment slowly.
2. **One mailbox doing everything.** 200 emails/day from one mailbox. Instant spam.
   Fix: Multiple mailboxes per domain. 30/day per mailbox max.
3. **No A/B testing.** Same copy forever. Ignorance about what works. Fix: Always
   run at least one A/B test per sequence.


## Output Format

The agent delivers a sequencing platform setup and optimization plan matched to the user's volume, persona, and budget:

- **Platform Recommendation** (when selection is requested): side-by-side comparison of Smartlead, Instantly, Salesloft, Outreach, and Lemlist on mailbox limits, warmup capability, multi-channel support, and price per seat/mailbox
- **Mailbox Configuration Plan:** domain count, mailboxes-per-domain (max 3), daily send cap per mailbox (30), warmup timeline (2-week minimum with daily increment schedule), and auto-rotation setup
- **Sequence Architecture:** 4-email + 2 multi-channel touchpoint plan with day-gap, word-count target, and stated objective per step (intro → value → social proof → break-up + LinkedIn connect + call)
- **A/B Test Setup:** subject line and copy variants, split percentage (50/50 or 33/33/33), winning metric (positive-reply rate), and minimum sample size before declaring winner
- **Deliverability Checklist:** SPF/DKIM/DMARC status per sending domain, custom tracking domain confirmation, warmup progress gate, bounce rate threshold (< 3%), and spam-trap monitoring setup

## Quality Check

Before delivering, verify:
- [ ] All required sections complete
- [ ] Output matches the user's stated need
- [ ] No vague or unsupported claims
- [ ] Frameworks cited where applicable

## Execution Artifacts

- `references/framework-notes.md` — named frameworks, citation anchors, and operating assumptions
- `templates/output-template.md` — copy-paste deliverable structure for the user
- `scripts/check-output.py` — local checklist validator for required sections
This skill includes lightweight artifacts the agent can load on demand:
- `references/platform-comparison.md` — Smartlead, Instantly, Salesloft, Outreach, Lemlist
- `templates/sequence-architecture.md` — 14-day multi-channel cadence
Use the artifacts when the user asks for an implementation-ready deliverable, a repeatable workflow, or a quality check rather than generic advice.
