MailCull is built to do one job clearly: help you find the addresses in a list that look safe, risky, clearly bad, or uncertain before you send.
The basic workflow
1. Create an account
Start with a free MailCull account so you can access the workspace.
2. Upload a CSV in Verify List
Upload the file you want to review. MailCull scans the CSV, finds the email column, and processes the addresses it detects.
3. Review the status breakdown
Each address is grouped into one of four statuses:
- Deliverable
- Risky
- Undeliverable
- Unknown
4. Filter and export
Use the results to decide what to keep, what to review, and what to remove before the next send.
5. Use Verify Email when needed
If you only need to check one address, use Verify Email instead of uploading a full file.
What MailCull checks
MailCull focuses on practical list-quality signals such as:
- syntax
- typo patterns
- disposable-domain signals
- domain and MX availability
It does not try to be an everything platform. The goal is to help you make better list decisions quickly.
