# SMTP

### SMTP Integrations

Integration via SMTP (Simple Mail Transfer Protocol) is a process that enables various applications, systems, or programs to communicate in order to transfer email messages from one mail server to another. Connecting to EmailLabs via the SMTP protocol offers a wide range of benefits and possibilities related to effective email sending and improved deliverability.

### General Configuration Instructions

If you were unable to find dedicated instructions for your software, we encourage you to use the general description provided below:

To configure email sending via EmailLabs, you need to assign the following data to the outgoing mail server settings in your system:

* **Server name:** smtp.emaillabs.net.pl 
* **Username and password:**
  * Data needed for integration via SMTP can be found in the EmailLabs panel in the section: **Email API -> Settings -> SMTP Accounts**.<br>

  * Remember to enter the login in the format `1.accountname.smtp`
* **Encryption:**&#x20;
  * option 1: TLS/STARTTLS; ports: 587, 2525, 25
  * option 2: SSL; port: 465

{% hint style="info" %}
NOTE:&#x20;

* After each update of the integration data, wait about **15 minutes** for the changes to propagate correctly in the system.&#x20;
* If you have problems sending despite correctly filled data, **try changing the port and/or encryption type** to match the requirements of your system.
  {% endhint %}

### Configuration and Security

To ensure effective and secure SMTP communication, please remember a few key aspects:&#x20;

* **Sender Authorization** – enables domain authorization, which protects the account against unauthorized sending and reduces the risk of phishing attacks. More information: [Senders Authorization](/en/email/sender-security/senders-authorization.md)
* **Authorization and authentication** – requires the use of SMTP credentials in the form of a login and password or authentication with an API key. The login format is 1.accountname.smtp, and the password can be set independently in the panel in the Email API > SMTP Accounts > SMTP Account Settings. More information: [SMTP Server Password](/en/first-steps/smtp-server-password.md)
* **TLS encryption** – ensures the confidentiality of data transmission, minimizing the risk of message interception. Our servers support TLS encryption by default.
* **IP Authorization** – allows you to restrict access to the SMTP server to specific IP addresses only. More information: [IP Authorization](/en/first-steps/security/ip-authorization.md)
