THE SMTP (Simple Mail Transfer Protocol) is a standard communication protocol that allows emails to be sent over the Internet.

THE SMTP is used for:

• Sending bulk emails in marketing campaigns.
• Manage email transfer between mail servers.
• Ensure secure communications with authentication and encryption protocols such as SSL/TLS.

1. Creating the email

When you compose an email, whether through an email client or an email marketing platform, you send the email to an SMTP server.

2. Transmission to SMTP server

The SMTP server takes care of routing the message to the destination server. The SMTP server verifies that the recipient's address is valid and provides authentication to prevent the email from being classified as spam.

3. Transfer to the receiving server

The email is then forwarded to the recipient's receiving server, which can be configured in IMAP Or POP3, before being placed in the user's inbox.

4. Deliverability and Receipt

When the email arrives at its destination, its deliverability depends on the sender's reputation, authentication configurations, and spam filters. If everything is configured correctly, the message arrives in the recipient's inbox.

Email authentication is crucial to ensure its legitimacy. Use the protocols SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) to prove that the email is from you and prevent it from being marked as spam.

3. Use SSL/TLS security

To secure email sending, configure your SMTP server to use SSL Or TLS in order to encrypt the data sent. This ensures that your emails are not intercepted or altered during transfer.

4. Monitor campaign performance

Once your SMTP server is set up, it is essential to track the performance of the emails sent. Use analytics tools to measure the open rate, click rate, bounce rate, and adjust your campaigns based on the data obtained.
