What is an outgoing mail server?

An outgoing mail server is like a digital post office that sends your emails from Odoo to the recipients. It ensures that all emails that you want to send from Odoo actually reach the recipient.

Why do I need an outgoing mail server in Odoo?

The outgoing mail server is required if you:

• Want to send automatic emails to customers (e.g. invoices, quotations)
• Want to send order confirmations
• Want to send reminders automatically
• Want to communicate with your customers directly from Odoo
• Want to send employee notifications

What happens if I do not set up an outgoing mail server?

Without a mail server set up:

• No emails can be sent from Odoo
• Automatic notifications do not work
• Important business processes may come to a standstill
• Your customers will not receive automatic updates

What information do I need for the setup?

You will need

• SMTP server address (e.g. smtp.gmail.com)
• Port number (usually 587 or 465)
• Your e-mail address
• The password or app-specific password
• Encryption type (usually SSL/TLS or STARTTLS)

What are the advantages of a correctly set up mail server?

With a functioning mail server:

• Your communication runs automatically
• Save time by sending emails automatically

• You have centralised communication
• Can you use email templates
