Over 40,000 companies are building great apps and email programs with Mailjet.
Mailjet’s free SMTP server integrates easily with any system. You can update your configuration using our SMTP server, one of the supported ports, and simply authenticate with your credentials (like an API key or secret key).
Mailjet supports a variety of ports with our SMTP relay, offering you greater flexibility. You can choose the port that is most suitable for you depending on your email client or ISP and have access to either TLS or SSL encryption to ensure your emails are secure.
With our SMTP relay, you will not only increase your chance of landing in the inbox, but your emails will get there faster. Easily set up SPF, DMARC, and DKIM records to authenticate your domain and start sending. Our deliverability support team will be there every step of the way to help get you set up, monitor, and maintain high deliverability rates.
Use your preferred Message Deliverability Agent or Message Transfer Agent (MTA) such as Postfix, Exim, or Exchange to send via Mailjet’s SMTP relay. You can also use PHP, Java, or any other frameworks or languages you prefer, making it easier for you to start sending immediately.
Mailjet’s real-time dashboard makes it easy for you to browse, filter and troubleshoot key performance indicators like opens, clicks, bounces, and unsubscribes, and more. You can also easily integrate in your systems to receive each event notification in real time thanks to webhooks.
