SMTP.com is a transactional email relay and delivery API service. It sends the emails your app or business generates, like confirmations, alerts, and notifications. The company has operated for more than 20 years and is part of the Ziff Davis Martech Division. It serves everyone from small senders to high-volume businesses that need dedicated infrastructure and account management.
SMTP2Go is a hosted email delivery service covering transactional, general, and marketing email. You connect your application or mail client — it supports sending directly from apps as well as from Outlook — point it at your own domains, and the service manages SPF and DKIM authentication for you automatically. It also inserts an unsubscribe link into your sends, which helps with compliance when you send anything beyond pure transactional messages.
