About SMTP2GO
SMTP2GO pairs heavy deliverability education with batch and scheduling API work for high-volume senders.
SMTP2GO's recent feed is dominated by long-form deliverability and compliance education: spam avoidance, transactional email and SMS explainers, unsubscribe rules, and GDPR/CAN-SPAM/CASL guidance. The one genuine product release is a set of API enhancements for scheduled sending, higher throughput, and more efficient large-batch sending. A cPanel automation plugin fix and a 24/7 human-support note round out the operational items.
