SMTP Integrations

Integration using the SMTP (Simple Mail Transfer Protocol) is a universal and reliable method to connect your application, CRM system, e-commerce platform, or any other tool with the MessageFlow sending infrastructure. This allows you to send emails directly from your systems, leveraging the performance, security, and delivery capabilities of our platform.

Below you will find all the information needed to configure an SMTP connection.

General SMTP Configuration Instructions

If your application or system allows you to configure an external SMTP server for outgoing messages, the following details will enable you to quickly connect with MessageFlow. In the outgoing mail settings of your system, enter the following data:

Server Name (Host): smtp.messageflow.com
Ports and Encryption: 587 (recommended, with TLS/STARTTLS encryption); 465 (with SSL encryption); 2525 (alternative port for TLS/STARTTLS); 25 (standard, use with caution)
Username: In the format 1.your_account_name.smtp (you can find the login in the MessageFlow panel: Email API -> Settings -> SMTP Accounts)
Password: The password set for your SMTP account in the MessageFlow panel

Note:

After any update to your configuration data (e.g., a password change), please wait up to 15 minutes for the changes to fully propagate throughout our system.
If you encounter connection problems, try using an alternative port from the list above, as some hosting providers may block standard ports.

Key Aspects of Configuration and Security

To ensure effective and secure communication via SMTP, remember these key elements that should be configured in the MessageFlow panel:

Sender Authorization: This is an essential step that confirms you have the right to send messages from your domain. Proper configuration of SPF and DKIM records is crucial for protecting your brand against spoofing and for improving deliverability.

Connection Authentication: Every connection to our SMTP servers requires authentication using your unique login and password. This is the primary mechanism protecting your sending account.

Transmission Encryption (TLS): Our servers support and prefer TLS encryption by default, which protects the content of your messages from being intercepted during transmission. Always use ports that support encryption (587, 465, 2525).
IP Address Authorization (Optional, Recommended): For an additional layer of security, you can restrict the ability to send via SMTP to only the trusted IP addresses of your servers.

Benefits of SMTP Integration

Choosing to integrate via SMTP with MessageFlow brings many benefits, combining simplicity of implementation with the advanced capabilities of our platform:

Speed and Performance: You benefit from our optimized infrastructure, designed to handle large volumes of messages in a very short time
High Deliverability: Your messages are sent from servers with a high reputation, which, combined with proper authorization (SPF, DKIM, DMARC), significantly increases the chance of them reaching the recipients' inboxes.
Centralized Monitoring and Analytics: All messages sent via SMTP are recorded in the MessageFlow panel. You have access to detailed logs, statistics on opens, clicks, bounces, and other key metrics.
Scalability: Our infrastructure is ready to handle both small and very large sending volumes, growing along with your needs.
Versatility: The SMTP protocol is a standard supported by a vast number of applications, platforms, and programming languages, which makes this integration extremely versatile.
