Tracking Checklist
Post-Launch Checklist

Introduction

Launching a cold email campaign without a checklist is like building a house without a blueprint. Something will be missed, and it will cost you — damaged reputation, wasted time, or missed opportunities.

This checklist covers every step from infrastructure setup to post-launch optimization. Use it before every campaign launch to ensure nothing is overlooked.

Who This Guide Is For

• Founders and sales teams launching their first cold email campaign
• Anyone who wants a systematic pre-launch verification process
• Teams that have had deliverability issues and want to prevent them

Key Takeaways

1. Complete all four categories before launching: infrastructure, content, targeting, tracking
2. Infrastructure is the foundation — do not skip DNS, warmup, or email hosting
3. Content should be personalized and tested before sending to your full list
4. Targeting should be verified — clean lists, right people, right companies
5. Tracking should be set up before the first email is sent
6. Use this checklist before every campaign, not just the first one

Infrastructure Checklist

Infrastructure is the foundation. If anything here is missing or misconfigured, your emails will not reach inboxes regardless of how good your content is.

Domain purchased from a reputable registrar (.com, brand-adjacent)
Email hosting set up (Google Workspace or Microsoft 365)
3–5 mailboxes created with real names (jane@, mike@, etc.)
SPF record configured and verified
DKIM record configured and verified
DMARC record configured and verified
DNS propagated and verified with MXToolbox
Domain warmed up for 2–4 weeks
Sender reputation healthy (check Google Postmaster Tools)
Domain not on any blacklists (check MXToolbox)

⚠️ Warning

Do not skip warmup. A new domain that immediately sends 100+ emails per day will be flagged as spam. Always warm up for 2–4 weeks before launching.

Content Checklist

Your content needs to be written, personalized, and tested before sending to your full list:

Cold email written following the 5-part structure (subject, opener, context, value, CTA)
Subject line under 50 characters, no clickbait
Opening line personalized for each recipient
Value proposition is specific and relevant
CTA is a low-friction question or soft ask
Email is under 150 words
Follow-up sequence has 4–6 emails with unique angles
Test emails sent to yourself — checked on mobile and desktop
No spelling or grammar errors

💡 Tip

Send test emails to yourself first. Check how they look on mobile, in different email clients, and with images on/off. Fix any issues before sending to your list.

Targeting Checklist

Your list needs to be built, verified, and segmented before sending:

Prospect list built targeting decision makers at ICP-matching companies
List verified with a dedicated email verification tool
Invalid addresses, catch-all domains, and role-based emails removed
List segmented by industry, role, or company size
Personalization fields added (first name, company, trigger)
Do Not Contact list updated — no one from previous opt-outs
List size appropriate for your inbox capacity (50–80/day per inbox)

⚠️ Warning

Never send to an unverified list. A single campaign with a 10% bounce rate can damage your sender reputation for weeks. Always verify before sending.

Tracking Checklist

Set up tracking before the first email is sent so you can measure results from day one:

Email tool connected with analytics enabled
Campaign tagged for easy identification
UTM parameters added to any links in emails
Tracking spreadsheet or CRM set up for additional data
Bounce rate alerts configured (pause if >3%)
Reporting cadence defined (daily, weekly, monthly)

💡 Tip

Use the ColdMailCalculator Inbox Readiness Score to verify your entire setup in one place. It checks DNS, warmup, and reputation before you send.

Post-Launch Checklist

After launching, monitor and optimize continuously:

Monitor open rates daily — should be 40–60%
Monitor reply rates daily — should be 5–15%
Monitor bounce rates in real-time — pause if >3%
Respond to replies within 24 hours
Track positive vs. negative replies
Review metrics weekly — adjust targeting or messaging if needed
Re-verify list every 3–6 months
Warm up new inboxes before adding volume

💡 Tip

If reply rate drops below 3% for two consecutive weeks, pause and audit your campaign. Something has changed — find it before continuing.

Summary

Launching a cold email campaign requires completing four categories: infrastructure (DNS, warmup, email hosting), content (writing, personalization, sequences), targeting (list building, verification, segmentation), and tracking (metrics, tools, alerts).

Frequently Asked Questions

How long does the full setup take?

Infrastructure setup (domain, email, DNS) takes 1–2 hours. Warmup takes 2–4 weeks. Content and targeting take 1–2 days depending on list size. Total time from start to first send: 2–5 weeks.

Do I need to complete every item on the checklist?

Yes. Every item exists for a reason. Skipping any item increases the risk of deliverability issues, spam complaints, or wasted outreach. The checklist is the minimum viable launch process.

Should I use this checklist for every campaign?

Yes. Things change between campaigns — domains age, reputation shifts, lists go stale. Run the full checklist before every campaign launch to catch issues early.

What if something on the checklist fails?

Fix it before launching. Do not proceed with known issues. A failed DNS check, unverified list, or missing tracking will cost you more time and reputation than delaying the launch.
