About SmtpJS

webatla tracks 4,108 live websites using SmtpJS, 0.0% of every site we index. Download the full list of websites that use SmtpJS as a daily JSONL export. Every record includes the domain plus DNS, WHOIS, IP address, hosting country and global rank.

SmtpJS is a lightweight JavaScript library that enables sending emails directly from client-side JavaScript code via SMTP. It works by routing email requests through a relay service, allowing web developers to trigger email sending from browser-based applications without a dedicated server-side backend.

SmtpJS is commonly used for simple contact forms, notification systems, and small web projects where setting up a full email server infrastructure is not practical. While convenient, security-conscious developers note that using SmtpJS with real SMTP credentials in client-side code can expose those credentials, so it is best suited for low-stakes applications or secured environments. The library integrates with services like ElasticEmail to handle the actual email delivery.
