The Ultimate Klaviyo Email Marketing Checklist: 30 Things to Review Before Every Campaign
Sending an email campaign takes only a few minutes.
Building one that generates opens, clicks, conversions, and revenue requires much more preparation.
Successful businesses don't simply write an email and press Send.
They follow a structured process that minimizes mistakes and maximizes performance.
Use this checklist before every campaign to improve your results.
Strategy
1. Define Your Campaign Goal
Know exactly what success looks like.
Examples:
• Sales
• Leads
• Product Launch
• Webinar Registration
• Customer Education
2. Know Your Audience
Identify who should receive the email.
Avoid sending every campaign to your entire list.
3. Segment Your Audience
Use Klaviyo segmentation to target:
• New subscribers
• Existing customers
• VIP customers
• Repeat buyers
• Inactive subscribers
4. Review Previous Campaign Results
Learn from previous campaigns.
Check:
• Open Rate
• Click Rate
• Conversion Rate
• Revenue
5. Send Valuable Content
Ask yourself:
"Does this email genuinely help the reader?"
Value always comes before promotion.
Subject Line
6. Write a Clear Subject Line
Keep it:
• Short
• Relevant
• Easy to understand
7. Test Subject Line Variations
Use A/B testing whenever possible.
Small changes can produce meaningful improvements.
8. Optimize Preview Text
Your preview text should complement—not repeat—the subject line.
Design
9. Use Consistent Branding
Maintain:
• Logo
• Colors
• Typography
• Tone
Consistency builds trust.
10. Optimize for Mobile
Most subscribers read emails on their phones.
Ensure:
• Readable text
• Large buttons
• Responsive layouts
11. Use High-Quality Images
Compress images to improve loading speed.
Avoid oversized graphics.
12. Balance Images and Text
Too many images may reduce deliverability.
Keep a healthy balance.
Content
13. Focus on One Primary Message
Avoid trying to communicate too many ideas in one email.
One clear objective performs better.
14. Include One Strong Call-to-Action
Examples:
• Shop Now
• Book a Call
• Download Guide
• Learn More
Make your CTA obvious.
15. Personalize the Email
Use customer information such as:
• First name
• Purchase history
• Product recommendations
16. Proofread Everything
Check:
• Grammar
• Spelling
• Formatting
Small mistakes reduce professionalism.
17. Test Every Link
Verify every button and hyperlink.
Broken links cost conversions.
Deliverability
18. Verify Sender Information
Ensure your sender name and email address are recognizable.
Subscribers trust familiar brands.
19. Avoid Spam Triggers
Avoid excessive:

Natural language performs better.
20. Authenticate Your Domain
Proper authentication improves deliverability.
Use:

Healthy lists improve deliverability.
Automation
22. Verify Automation Triggers
If using a flow, confirm:

Broken personalization reduces trust.
24. Check Product Recommendations
If using dynamic product blocks, verify they load properly.
Performance
25. Schedule at the Right Time
Review previous campaign data to determine when your audience is most active.
26. Monitor Live Performance
After sending, monitor:
• Opens
• Clicks
