Overview

Mailgun and SMTP2GO both handle transactional email delivery but with different focuses. Mailgun is a comprehensive developer platform with API-first design. SMTP2GO specializes in reliable SMTP relay with simpler setup. See our Mailgun comparison for more alternatives.

API-First vs SMTP Specialist

Mailgun is built API-first. While they offer SMTP, their REST API is the primary interface with SDKs in 8+ languages, detailed webhooks, and comprehensive documentation.

SMTP2GO specializes in SMTP relay. Their API exists but SMTP is their strength. If your systems already use SMTP, SMTP2GO offers a smooth path.

Developer Tools

Mailgun provides more developer features: built-in email validation, detailed analytics, sophisticated webhooks, and broad SDK support. It is a complete developer toolkit for email.

SMTP2GO is simpler with fewer developer features. The dashboard is clean, the SMTP works reliably, and support is good. But you will not find the same depth of tools.

Setup Experience

SMTP2GO is often faster to set up, especially for SMTP relay. Configure your SMTP settings, verify your domain, and start sending. Many teams are up and running in minutes.

Mailgun has more to configure but offers more power. The tradeoff is complexity for capability.

Pricing Comparison

At 100,000 emails monthly, both cost about $75. Pricing is similar at most volumes. The choice is about features and approach, not cost.

For unified email marketing and transactional at simpler pricing, consider Sequenzy.

Making the Decision

Choose Mailgun for comprehensive developer tools, API-first integration, and advanced features like email validation. Choose SMTP2GO for simple, reliable SMTP relay with straightforward setup. For SaaS with Stripe integration, Sequenzy offers a unified approach.

The Sequenzy Alternative

For SaaS companies, Sequenzy combines transactional and marketing email with native Stripe integration, smart segmentation, and per-subscriber pricing instead of per-email costs.
