Step 1 — Gather context

If the user's request already provides most of this context, skip directly to the relevant step. Lead with your best-effort answer using reasonable assumptions (stated explicitly), then ask only the most critical 1-2 clarifying questions at the end — don't gate your response behind gathering complete context.

Step 2 — Sequence setup in Apollo

Read references/platform-guide.md for detailed module documentation, pricing, integrations, and data model.

Key settings — configure these for every sequence (non-negotiable):

• Stop on reply: Always enable. Auto-pause the sequence when a prospect replies. There is zero reason to keep emailing someone who responded — it damages trust and wastes sends.
• Stop on meeting booked: Always enable. Once the goal is achieved, stop the sequence.
• Business hours sending: Always enable. Send during the recipient's business hours (typically 8am-6pm in their timezone). Emails arriving at 2am look automated and get buried.
• Daily send limits: Start conservative — 50-100 emails/day per mailbox for warm, established mailboxes. For new mailboxes, start at 20-30/day and ramp up over 2-3 weeks. Exceeding safe limits tanks sender reputation fast.
• Delay between steps: Use 2-3 business days between email steps. Shorter gaps feel aggressive; longer gaps lose momentum. Increase to 4-5 days after 3+ unreplied emails to avoid fatigue.
• Sequence type: Use Automatic for email-only sequences (hands-off, sends on schedule). Use Manual for multi-channel sequences that include calls or LinkedIn steps — Auto mode skips non-email steps entirely.

For full cadence strategy — including messaging arc, multi-channel touch patterns, and email copy — use /sales-cadence.

You no longer need the platform guide details — focus on the user's specific situation.

Gotchas

• Don't launch sequences without verifying domain authentication. Claude often generates sequence setup guides without checking SPF/DKIM/DMARC. Missing domain auth is the #1 cause of emails landing in spam. Check it before anything else.

• Don't set high daily sending limits on new mailboxes. New mailboxes must be ramped up gradually (20-30/day → 50-75/day over 2-3 weeks). Claude defaults to recommending 100+ sends/day, which will tank deliverability on a fresh mailbox.

• Don't use Apollo's "Auto" sequence type for multi-channel cadences. Auto sequences only work for email steps. If the cadence includes calls or LinkedIn touches, use "Manual" sequence type — otherwise those steps are skipped entirely.

• Don't evaluate A/B tests too early. Claude will analyze test results after 30-40 sends. You need at least 100 sends per variant for statistically meaningful results. Premature conclusions lead to wrong optimizations.

• Don't ignore the Deliverability Command Center. Apollo has a built-in deliverability monitoring dashboard that most users never check. It shows domain health, bounce rates, spam complaints, and sending patterns. Review it weekly.

• Self-improving: If you discover something not covered here, append it to references/learnings.md with today's date.

Related skills

• /sales-cadence — Handoff: for email copy strategy, A/B testing frameworks, and multi-channel cadence design beyond Apollo. Once your Apollo sequence is configured, use /sales-cadence to write the actual email copy, design the messaging arc across steps, plan multi-channel touch patterns, and build A/B testing strategies for content. This skill handles Apollo execution; /sales-cadence handles the content and strategy layer.

Examples

Example 1: Setting up a new sequence

User says: "I need to set up a 5-step email sequence in Apollo for cold outbound to VP Marketing" Skill does:

1. Configures sequence settings (auto type, business hours, stop on reply)
2. Sets up 5 steps with recommended timing gaps
3. Configures mailbox rotation across 3 connected email accounts
4. Walks through the deliverability checklist Result: Sequence configured and ready for contacts — user runs /sales-cadence to write the actual email copy

Example 2: Fixing deliverability

User says: "My Apollo sequence open rate dropped from 55% to 25% over the past month" Skill does:

1. Checks domain authentication (SPF/DKIM/DMARC) status
2. Reviews sending volume and mailbox health in Deliverability Command Center
3. Identifies likely cause (sending volume spike, domain reputation issue, or content triggering spam filters)
4. Recommends remediation steps (reduce volume, warm up new mailbox, adjust content) Result: Deliverability diagnosis with a recovery plan

Example 3: A/B test setup

User says: "I want to A/B test my first email's subject line in Apollo" Skill does:

1. Verifies the user is on Professional+ plan (A/B testing not available on Basic)
2. Walks through creating Variant B in the sequence editor
3. Sets 50/50 split and defines success metric (open rate for subject line tests)
4. Recommends waiting for 100+ sends per variant before evaluating Result: A/B test configured with clear evaluation criteria

Troubleshooting

Sequence not sending

Symptom: Contacts added to sequence but no emails going out Cause: Mailbox not connected, sequence paused, contact missing email, or daily limit reached Solution: Check sequence status (active?), verify mailbox connection in Settings > Email, confirm contacts have email addresses, review daily send limits.

Emails going to spam

Symptom: Open rates below 20%, recipients reporting spam Cause: Missing domain auth, volume too high, spammy content, or domain reputation damage Solution: Verify SPF/DKIM/DMARC. Reduce volume to 20-30/day per mailbox. Remove spam trigger words. Check domain reputation via Google Postmaster Tools.

High bounce rate

Symptom: Bounce rate above 3% Cause: Stale email data, unverified addresses, or catch-all domain issues Solution: Stop the sequence immediately. Verify remaining contacts via /sales-enrich. Remove bounced contacts. Clean your list before resuming.
