Definition
A pre-send checklist is a systematic verification process that email teams follow before sending a campaign. It ensures that every element of the email — content, design, links, tracking, compliance, and technical configuration — has been checked and approved.
A pre-send checklist prevents the most common email errors: broken links, missing personalisation, compliance violations, and rendering issues. A team that consistently uses a pre-send checklist catches 90%+ of potential issues before they reach subscribers.
Essential Pre-Send Checks
| Category | Check | Tool / Method |
|---|---|---|
| Content | Subject line, preview text, body copy proofread | Manual review |
| Links | All links work and go to correct destinations | Link checker |
| Personalisation | Merge tags render correctly, test with dummy data | Test send to self |
| Design | Mobile + desktop rendering, image loading | Litmus / Email on Acid |
| Compliance | Unsubscribe link works, physical address present | Manual check |
| Tracking | UTM parameters, pixel, click tracking active | ESP preview |
| Segment | Correct audience selected, exclusion rules applied | Segment preview |

Pre-Send Best Practices
- Make it a team process: Have a second team member review the checklist. Fresh eyes catch issues the creator missed.
- Automate what you can: Link checkers, spam testers, and preview tools automate parts of the checklist. Use them.
- Build checklists into your ESP: Many ESPs support pre-send validation rules that flag common issues automatically.
- Review and update quarterly: Common errors change as email clients and regulations evolve. Update your checklist accordingly.
