If your clients aren’t receiving your emails, one common reason could be the use of a free email address (e.g., myname@gmail.com or myname@yahoo.com). Here’s why this can affect deliverability—and how to fix it.

1. Avoid Using Free Email Addresses

  • Free email addresses are considered private and are more likely to be flagged as spam by email service providers.

  • Using a private address for professional communications may also violate CNIL (or broader European Data Protection Board) guidelines.

Solution:
We strongly recommend using a professional email address from a domain hosting provider (e.g., OVH, IONOS, or Gandi).
For example: contact@mycompany.com


This improves deliverability and gives you access to advanced authentication options.

2. Update Your Sender Address

▸ For Transactional Emails

To update the email address used for system notifications (e.g., order confirmations):

  • Access your account Settings, then open the Emails tab.

  • Set your sender name and email address.

  • Add your custom sending domain and follow the configuration steps:

    • Log in to your DNS hosting provider.

    • Create the required TXT records to configure validation codes, DKIM, and DMARC.

    • Update your SPF record to include the following mechanism:
      include:learnybox.com

Once everything is correctly configured, Learnybox will display the message:
Perfect! Your sender email address is properly configured

▸ For Marketing Emails (LearnyMail)

To update the address used for your normal emails, newsletters, broadcasts, or email sequences:

  • Navigate to Marketing → Emails → Settings tab

  • Set your default sender name and email address.

  • Tick the checkbox to apply this information to all existing emails, ensuring outdated sender details are overwritten.

By using a professional email address and properly configuring your domain’s DNS records, you greatly improve the chances of your emails being successfully delivered to your clients.
