Extension Features

Advanced newsletter settings

Get plenty of adjustment opportunities. The Magento SMTP extension adds an advanced set of setting fields to the Mail Sending Settings tab in your admin panel to configure the SMTP server in a more flexible way. Authentication and connection parameters can be set up according to your needs.

Trusted email provider support

Entrust your emails to reliable and secure email servers like Gmail, Outlook, and Yahoo. Integrate the SMTP server of your preferred email provider into your Mail Sending Settings and work with it no problem. Instead of PHP Sendmail, with our custom Magento module, your emails will be channeled through the system of your choice.

2-layer security for connection

Add extra security to your email channel. Our Magento 2 SMTP module secures the information on your server for it not to be lost or disclosed to third parties. A few more settings to the standard Magento settings set ensures the protection of your emails and their content. The 2-layer security for the connection reduces the chances of email phishing and other types of fraud.

Improved email reliability

Custom SMTP Magento 2 extension is not an email marketing tool and does not send any emails. SMTP advanced settings make your emails more reliable so that your emails were not marked as spam or rejected by the email system of the recipient.

I’m running several stores, shall I buy a separate extension for each of them or it is possible to use one extension?

You can use one extension per one live Magento installation. It means that if you run multiple stores on same one Magento installation, you just buy our extension once and then use it for all your stores.
In case your stores run on separate live Magento installations, you need to buy an extension for each of them.
