How SMTP Works

How SMTP Works

Key Features of Magento 2 SMTP

Customizable SMTP server in Magento store

Easily configure and customize Magento 2 SMTP service directly from the admin panel. Mageplaza SMTP extension offers full control over SMTP server settings, including the SMTP host, SMTP port, protocol, authentication, username, password, and return-path email.

Various email service providers supported

Using your own SMTP server is great, but you can save time in configuration for your email business by selecting one of 34 popular email services.

Testing email before going live

Verify if the current email setting is working correctly or not. If the configuration is correct, a success email will be sent. Otherwise, the administrator will receive an error notification.

Track sent-email logs

Thanks to the Mageplaza SMTP module, admins can monitor the list of sent emails at any time with the email log grid. The grid keeps all sent email logs and permits the user to check back who/how they were sent.

Developer mode

This function allows admins to preview and test the emails before sending real emails, ensuring configuration has no errors and complete accuracy.

All features

Customizable SMTP server

In the Magento 2 SMTP configuration, you can select different authentication methods to make sure secure email transmission:
check
Login
When store admins select the Login method to Magento 2, they must provide a valid username and password for the SMTP server. This guarantees that emails are sent securely through the SMTP server, preventing unauthorized access.
check
Plain
Similar to the Login method, plain authentication also uses a username and password. However, it sends the SMTP credentials in readable text without any encryption or coding.
check
CRAM-MD5
CRAM-MD5 (Challenge-Response Authentication Mechanism) is a more secure method that uses a challenge-response mechanism to authenticate the sender. It enhances security by not sending the password in plain text.

34 popular SMTP providers

Store admins can choose a host provider from a dropdown menu in the backend. The selected provider will send emails from the online store. Here are the 34 specific hosting providers:
check
Gmail/GSuite
check
Office365
check
Amazon SES
check

Email testing

In the backend, the Send Test Email field is to check the operation of the extension. This field contains 2 sections:
check
Send from: Select one of the five Magento email senders, including general contact, sales representatives, customer support, custom email 1, and custom email 2.
check
Send to: Enter the email address to which admins want to test the email.
To test the email, you need to follow the steps below:
check
Fill in the email addresses in the Send From and Send To sections.
check
Click the Test Now button.
Keep in mind that the final desire of every sender is for the newsletter to reach the right destination, to their mailbox, not their spam box. Take advantage of running testing; the visual examination can be performed as you can have a general look back at the intended email again.

Track sent-email log grid

With the SMTP authentication, store admins can access a detailed email log grid. This grid will include all email log information, such as ID, subject, status (whether the email was sent successfully or failed), time of creation, and the ability to take action (such as viewing or resending the email). By having this information at their fingertips, store owners can effectively monitor and manage all their emails.
In addition, the self-test email feature is designed to test whether the SMTP configuration is set up correctly. By sending test emails and checking the detailed logs, users can identify potential email sending issues and the cause of email sending errors. This approach makes it easier to find and fix any errors in the email-sending process.

Developer mode

Developer Mode is a useful feature for testing email settings and email debugging. When store admins enable the developer mode, Magento will not actually deliver any emails to the recipients. Instead, the email information is logged. By doing so, admins can preview and test the emails before actually sending them, ensuring everything is configured correctly without sending real emails.
Here are some key points about the Developer Mode:
check
Email Logging
All emails are logged so you can see the content and ensure everything is set up correctly.
check
Testing
It helps in testing the email configurations without worrying about emails being sent to actual customers.
check
Debugging
You can easily detect and fix any issues with your email settings by previewing the logs.

Clean email log automatically

The “Clean Email Log” function allows you to delete all SMTP email logs automatically after a specified number of days. For example, if you set it to 30 days, any email logs older than 30 days will be automatically removed.
Benefits of cleaning email log automatically:
check
Storage management
By automatically deleting old email logs, you can prevent your database from becoming cluttered with outdated information.
check
Time-Saving
Instead of manually sorting and deleting old email logs, you can automate the process. By doing so, you can save time in cleaning old email logs.
check
Security and privacy
Regularly clearing out old email logs helps maintain the security and privacy of your email communications. This way ensures that sensitive information is not stored longer than necessary.

Resend email

With the Mageplaza SMTP solution, you can easily identify failed emails in the email log grid. This grid provides a comprehensive view of all outgoing emails, including those that failed to send.
When you have identified the failed emails, you can resend them directly from the email log with just a few clicks. By resending these emails, you ensure that important communications, like order confirmations or password resets, are successfully delivered to their intended recipients.
This feature is particularly valuable for maintaining customer satisfaction and trust, as it helps prevent critical emails from being overlooked or lost.

Provide multi-store support

This Magento 2 extension supports multiple stores and languages. It optimizes transactional email delivery to ensure that every message reaches your customers reliably, no matter which store or language they use. Therefore, you can efficiently manage your email systems across a multistore and multilingual setup.

Blacklist email pattern

In Magento 2, the Blacklist Email Pattern feature allows store owners to prevent specific customer email patterns from receiving emails generated by your system.
For example, if you want to block all emails going to addresses that end with @example.com, you can set up a pattern to block *@example.com. By doing so, any email generated by your Magento store (like order confirmations, newsletters, etc.) will not be sent to any address that matches this pattern.
Key benefits of using blacklisting email patterns:
check
Spam prevention
By blocking suspicious or non-legitimate email patterns (e.g., fake domains or disposable email services), you can reduce the risk of emails being flagged as spam by external services.
check
Better resource management
Preventing emails from being sent to unwanted addresses can help optimize your server's resources, improving overall system performance and email deliverability rates.
check
Compliance with policies
This feature helps businesses comply with legal or internal policies by restricting email communications with certain users or domains.

Extension compatibility

This extension works well with Magento 2 One Step Checkout, and Magento 2 Ultimate SEO extension
