What SMTP2GO is
SMTP2GO provides SMTP and API email delivery for businesses and individual senders, with real-time reporting on deliveries, bounces, opens, clicks, unsubscribes and spam reports. SPF and DKIM authentication are supported for sender domains. Its API can send standard or MIME emails, retrieve activity and statistics, manage domains and users, and configure webhooks. Paid plans can send SMS to as many as 100 destination addresses at once through the API. The Email Testing tool previews messages in more than 50 email clients; spam-filter testing is available on Professional-level plans. Listed integrations include WordPress, cPanel/WHM, Slack and open-source libraries for several programming languages and Django. Data centers are in the United States, European Union and Australia, with storage location selected by account location. Email is encrypted at rest and deleted after 35 days by default; paid accounts can extend activity storage or archive for three months to five years. The free plan allows 1,000 emails monthly. Starter costs $10/mo.
