SMTP2GO

SMTP2GO is a cloud-based email delivery service that helps organisations send transactional and marketing email reliably without depending on the limitations of their own mail servers or hosting providers. It addresses a common problem: messages sent from applications, websites, devices and office systems are frequently delayed, blocked or filtered as spam when they originate from poorly configured or shared infrastructure. SMTP2GO routes outbound mail through a globally distributed network of servers with established sender reputation, handling authentication and delivery optimisation so that messages are more likely to reach the inbox. The service can be used as a simple SMTP relay, configured in almost any application or device, or through a REST API for developers who want tighter integration. Its approach combines dependable infrastructure with detailed reporting, so that senders can see what happened to each message rather than treating email as a black box.

Features include real-time delivery reports, open and click tracking, bounce and spam complaint handling, and searchable activity logs. SPF, DKIM and DMARC support helps authenticate sending domains, while dedicated IP addresses are available for higher-volume senders. The archiving feature stores copies of sent emails for later retrieval, supporting compliance, dispute resolution and record-keeping requirements. Additional tools include email templates, webhooks, subaccounts for agencies and resellers, and SMS sending. SMTP2GO integrates with content management systems, ecommerce platforms, CRMs and many other applications, and supports scanners, printers and other devices that need to send notifications. The service is suitable for small businesses, developers, IT managers, managed service providers and larger enterprises that need predictable deliverability. Data centres in several regions help with performance and data residency considerations, and round-the-clock support is part of the offering. A free version is available for low sending volumes and a free trial is offered, with paid plans starting from around USD 15 per month.
