About SMTP2GO
SMTP2GO leans into deliverability craft and 24/7 human support against transactional-email rivals.
Steady weekly cadence with a mix of deliverability-craft content (warmup ramps, send-frequency effects, attachment limits, authentication), compliance education (GDPR/CAN-SPAM/CASL), and brand differentiators (24/7 human support). The cPanel plugin post is the only direct product release note, shipping an update with bug fixes and an authentication-issue resolution.
