SMTP2GO is an SMTP relay for personal and transactional emails with analytics and deliverability tools, but no email forwarding1.
ImprovMX provides advanced email forwarding and optional SMTP sending, without SMTP2GO’s full sending features.
Choose SMTP2GO if you need free-tier SMTP sending, or advanced send tracking. Choose ImprovMX if you need email forwarding and are willing to use a paid plan for SMTP sending.
