Importing contacts into Mailpro takes under 5 minutes. Here's the step-by-step from source file to ready-to-send list.
1. Prepare your file
- Format: CSV UTF-8, XLSX, ODS or VCF
- First row = headers (Email, First name, Last name, …)
- One email per row, no whitespace
2. Start the import
- Log in to Mailpro
- Open Contacts → Import
- Select your file (drag-and-drop supported)
- Choose a destination list or create a new one
3. Map the columns
Mailpro auto-detects the matches. Adjust if needed:
- Email column → Email field (required)
- First name column → First name field
- Custom fields are created on the fly
4. Validate
Mailpro shows a summary: contacts added, duplicates skipped, rows rejected. Full detail in the import report.
Best practices
- Import in batches of 50,000 max
- Use double opt-in for new sign-ups
- Never reuse purchased lists — blacklist risk
- Include a GDPR notice on your collection form
