This module validates and normalizes the field email in the model res.partner.

As part of the normalization, email addresses are converted to lowercase.

Optionally, multiple partners can not be allowed to have the same address. This will not work with multiple comma-separated email addresses in the field, although validation and normalization are still supported in such cases.

Table of contents


Install python package email-validator: sudo pip install email-validator.

To not allow multiple partners to have the same email address, use the "Filter duplicate email addresses"/partner_email_check_filter_duplicates setting.

To validate that email addresses are deliverable (that the hostname exists), use the "Check deliverability of email addresses"/partner_email_check_check_deliverability setting.


This module integrate automatically in all of the view res.partner
