What it is
SMTP2GO is an SMTP and API email delivery service for businesses and everyday senders. It provides real-time reporting for deliveries, bounces, opens, clicks, unsubscribes, and spam reports, with SPF and DKIM support for sender domains. The API sends standard or MIME email, retrieves activity and statistics, manages domains and users, and configures webhooks. Paid plans can send SMS through the API to up to 100 destination addresses at once. Its Email Testing tool previews messages in more than 50 email clients and performs spam-filter tests on Professional-level plans. Official integrations include WordPress, cPanel/WHM, Slack, and open-source libraries for .NET, Go, Node.js, PHP, Python, Ruby, Rust, and Django. Data centers are located in the United States, European Union, and Australia. SMTP2GO says it is GDPR compliant and ISO 27001 and ISO 9001 certified. Email is encrypted at rest and deleted after 35 days by default. Attachments can reach 50MB per email.
