What is SMTP?
SMTP (Simple Mail Transfer Protocol) is the standard used to send emails between systems. It allows your application to send messages—such as confirmations or notifications—through an external server instead of handling delivery itself.
How Does it Work?
- Your system sends the message
- It connects to an SMTP server using credentials
- The message is sent securely (TLS)
- The server delivers it to the recipient
This means you can send emails without managing your own delivery infrastructure.
Key benefits of Cyberimpact SMTP

Use standard SMTP credentials to connect your website, CRM, or application—no API or custom integration required.
Reduce delivery issues with proper authentication
Emails are authenticated using SPF, DKIM, and return-path configuration, helping receiving servers verify your messages.
Support consistent delivery
Messages are signed and sent through managed infrastructure designed for stable delivery. Results still depend on your sending practices and recipient engagement.
Track delivery outcomes
See whether emails are delivered, deferred, or bounced so you can identify and resolve issues quickly.
