# Outbound Sequencing — Standard Operating Procedure

> Source: https://b2bprocess.com/outbound-sequencing
> Last updated: 2026-07-08. Adapt owners, tools, and thresholds to your organization.

## 1. Purpose

Outbound sequencing is the process of contacting prospects through a structured series of touches across channels — typically email, phone, LinkedIn, and occasionally video or direct mail — spaced over two to four weeks, with defined messaging per step and defined exits when a prospect replies, books, or opts out. The sequence turns prospecting from ad-hoc individual effort into a measurable, improvable system.

## 2. Scope & prerequisites

Implement formal sequencing when you have dedicated outbound capacity (even one SDR or a founder doing systematic outbound) and a defined ICP with a list of at least a few hundred target accounts. Prerequisites: a sending domain separate from your primary corporate domain, SPF/DKIM/DMARC configured, and a CRM in which replies and meetings are logged.

## 3. Roles & responsibilities

| Role | Responsibility |
| --- | --- |
| SDR / BDR | Executes touches, personalizes at tier, handles replies, keeps CRM dispositions clean. |
| SDR Manager | Owns sequence design, messaging quality, weekly performance review, and coaching. |
| Revenue Operations | Owns sequencing tooling, deliverability infrastructure, suppression rules, and reporting. |
| Account Executive | Partners on strategic-account plays; takes meetings and feeds back on lead quality. |
| Marketing | Supplies proof points, case studies, and air cover (ads/content) on target segments. |

## 4. Procedure

### Step 1: Define the target segment and trigger

**Owner:** SDR leadership + Sales leadership

Every sequence targets one segment with one reason to reach out now: a persona × industry × trigger combination (new VP of Sales hired, funding round, tech-stack signal, job postings). Sequences aimed at 'everyone in the ICP' produce generic copy and generic results.

- [ ] Pick one persona and one trigger per sequence
- [ ] Define the problem hypothesis this segment has
- [ ] Set entry criteria precisely enough to automate list pulls

### Step 2: Build and verify the list

**Owner:** SDR (with RevOps support)

Source contacts matching the entry criteria, enrich with direct dials and verified emails, and validate every address before sending — bounce rates above ~3% damage domain reputation for all future sends. Cross-check against CRM: open opportunities, customers, and active sequences are excluded.

- [ ] Enrich and verify emails; discard risky/catch-all addresses at volume
- [ ] Suppress existing customers, open opps, and recently-sequenced contacts
- [ ] Cap list size to what can be personalized at the chosen tier

### Step 3: Design the cadence structure

**Owner:** SDR leadership

Standard structure: 8–14 touches over 15–25 business days, mixing email, calls, and LinkedIn. Front-load effort in week one (email day 1, call day 2, LinkedIn day 3), space later touches wider. Every step has a purpose; 'just bumping this' is not a purpose.

- [ ] Map each step: day, channel, objective
- [ ] Alternate channels — calls answer the emails, emails answer the voicemails
- [ ] Define exits: reply, meeting booked, opt-out, disqualified

### Step 4: Write the messaging

**Owner:** SDR leadership + SDRs

Lead with the prospect's problem, not your product. First email: one observed trigger, one problem hypothesis, one clear low-friction ask, under 100 words. Later steps add proof (peer results, specific numbers) and vary the angle rather than repeating the ask. Write like a person; strip the marketing adjectives.

- [ ] Draft per-step templates with explicit personalization slots
- [ ] Add one proof point with a real number by step 3
- [ ] Prepare call scripts and voicemail lines matching the email narrative

### Step 5: Set up deliverability guardrails

**Owner:** RevOps / Email infrastructure owner

Send from warmed secondary domains, cap volume per mailbox (commonly ≤ 30–50 cold sends/day), throttle ramp-up, use plain-text emails, and monitor spam-rate and blocklist status. Rotate mailboxes before reputation degrades, not after.

### Step 6: Launch to a test cell first

**Owner:** SDR leadership

Run the sequence on 10–20% of the list for one to two weeks. Check deliverability (open proxies, bounce rate), reply sentiment, and meeting rate before committing the full list. Kill or rewrite sequences with high negative-reply rates immediately.

### Step 7: Execute daily with a task discipline

**Owner:** SDRs

Automated emails send themselves; the sequence lives or dies on the manual steps — calls made, LinkedIn touches sent, personalization done. Reps clear sequence tasks daily; overdue manual tasks are the leading indicator of a decaying outbound motion.

- [ ] Block daily call time aligned to prospect time zones
- [ ] Handle replies within hours: positive → book directly; objection → one thoughtful counter; negative → polite exit
- [ ] Log dispositions so reporting reflects reality

### Step 8: Review, A/B test, and retire

**Owner:** SDR leadership

Weekly: reply and meeting rates by sequence and by step; test one variable at a time (subject line, opener, ask) with enough volume to matter. Retire sequences after they saturate their segment or decay below the team floor — a sequence is an asset with a shelf life, not a monument.

- [ ] Weekly scorecard per sequence: sends, replies, positive replies, meetings
- [ ] One live A/B test per sequence maximum
- [ ] Archive with notes: what worked, for which segment, and why it was retired

## 5. Metrics to monitor

| Metric | Definition | Formula | Target |
| --- | --- | --- | --- |
| Positive reply rate | Replies expressing interest or a referral, as a share of prospects contacted. The quality metric that matters more than raw reply rate. | Positive replies ÷ prospects sequenced | 1–5% cold; higher with strong triggers |
| Meetings booked per 100 prospects | End-to-end sequence yield, normalizing for list size. | Meetings booked ÷ prospects sequenced × 100 | 1–3 for cold outbound |
| Bounce rate | Hard bounces as a share of sends — the deliverability early-warning light. | Hard bounces ÷ delivered attempts | < 2–3% |
| Task completion rate | Share of manual sequence tasks (calls, LinkedIn) completed on time. | Tasks completed on schedule ÷ tasks due | > 90% |
| Meeting hold rate | Booked meetings that actually occur — poor hold rates reveal pressure-booked, low-intent meetings. | Meetings held ÷ meetings booked | > 75% |
| Sequence-to-opportunity conversion | Share of sequenced prospects that become qualified pipeline — connects outbound activity to revenue. | Opportunities created ÷ prospects sequenced | 0.5–2% |

## 6. Known failure modes

| Failure | Symptom | Corrective action |
| --- | --- | --- |
| Volume worship | Thousands of sends, sub-1% replies, domain reputation sliding, ICP burning out. | Cut list size, raise personalization tier, lead with triggers; measure meetings per hour worked, not emails sent. |
| Email-only cadences | Reply rates decay as inboxes saturate; no phone connects because no calls are made. | Enforce multi-channel structure; coach and inspect the manual steps, which are where sequences actually differentiate. |
| Deliverability ignored until it breaks | Open rates collapse overnight; domain lands on blocklists; even warm emails go to spam. | Secondary sending domains, verified lists, volume caps, warm-up, and weekly reputation monitoring as standing infrastructure. |
| Personalization theater | 'I saw you went to [college]' openers that signal automation rather than research. | Personalize on business-relevant signals (trigger, initiative, stack) or don't pretend; segment-level relevance beats fake 1:1. |
| No exit criteria | Prospects who replied 'not now' keep getting step 7; angry replies and spam complaints follow. | Automated exits on any reply; explicit re-approach dates for 'not now'; global suppression honored across all sequences. |
| Sequences never retired | The team runs the same cadence for 18 months; results decay is blamed on 'the market'. | Treat sequences as having a shelf life; review quarterly, refresh messaging, and rebuild around new triggers. |
| Replies rot in inboxes | Positive replies answered days later; hard-won interest cools before the meeting is booked. | Reply SLA in hours; booking link or direct calendar offer in the first response. |
