Clean Customer Emails Exported from PrestaShop

✓ Tested Works with CSV, Excel, Google Sheets → JSON-LD Schema

By dataclean.to team · 2026-02-12

PrestaShop is an open-source e-commerce platform popular in Europe and Latin America. Customer email addresses are collected during account registration, checkout, and newsletter signup. Like other self-hosted platforms, PrestaShop's email data quality depends on the store's spam protection configuration. dataclean.to validates your PrestaShop customer export to remove spam registrations, fix international email formatting issues, and ensure your marketing reaches real customers.

The Problem

PrestaShop stores serving international markets face email quality challenges specific to multilingual e-commerce. Customer names and email addresses may contain accented characters (e, u, o) that are valid in email standards but cause encoding issues during CSV export. PrestaShop's default export uses the server's character encoding, which may corrupt non-ASCII characters in email addresses. Guest checkout creates customer records without account verification, and these entries frequently contain typos because the checkout flow prioritizes speed over validation. PrestaShop modules for newsletter signup and customer reviews create additional contact records that may duplicate the main customer table. The platform's multi-shop feature can result in the same customer having separate accounts across different storefronts with inconsistent email data. European customers using country-specific email providers (web.de, orange.fr, libero.it) have domains less commonly targeted by auto-correction tools, so typos in these domains go unfixed.

How to Fix It

Export customers from PrestaShop

In the PrestaShop back office, go to Customers > Customers and use the Export button. Choose UTF-8 encoding to preserve international characters. Include email, name, registration date, orders count, and shop association.

Upload to dataclean.to

Import the PrestaShop CSV. The platform handles UTF-8 encoded international email addresses and validates every entry for syntax, domain health, and deliverability across global email providers.

Fix encoding and character issues

Detect and repair email addresses where accented characters were corrupted during export. Restore proper formatting for international addresses that were mangled by incorrect character encoding settings.

Remove spam and guest checkout errors

Flag fake registrations from automated scripts and correct typos in guest checkout emails. Identify European email provider domain misspellings (wb.de instead of web.de, orage.fr instead of orange.fr).

Export validated customer data

Download the clean customer list with proper encoding preserved. Re-import into PrestaShop or use for email marketing campaigns targeting your international customer base.

Frequently Asked Questions

Why do PrestaShop exports have encoding issues?

PrestaShop's export encoding depends on the server configuration and PHP settings. If the server uses Latin-1 encoding but customer data contains UTF-8 characters, the export produces corrupted email addresses with garbled characters replacing accents and special characters.

Can I clean customers from multiple PrestaShop shops?

Yes. If you run a multi-shop PrestaShop installation, export customers from each shop and upload them to dataclean.to separately. The platform can help identify customers who exist across shops with different email addresses.

How do I handle PrestaShop newsletter subscribers separately?

PrestaShop stores newsletter subscriptions separately from customer accounts. Export newsletter subscribers through the Email Subscription module and upload that list to dataclean.to for independent validation.
