Transactional email delivery API and SMTP relay service for developers.

Deliverability blogging with one real API release buried in the run

transactional-emaildeliverabilityapismtpseo-content
◆Current state
Most of the feed is deliverability education and comparison content: a scan-to-email setup and troubleshooting guide, a third-party ranking from EmailToolTester, a tested top five of transactional email services, a spam-avoidance playbook, and a definitional piece on transactional email. The exception is June's API release, which added scheduled sending, throughput improvements and more efficient large-batch sending.
◆Where it's heading
SMTP2GO's product signal arrives roughly once a quarter and always concerns the sending path — scheduling, throughput, batch efficiency — aimed at high-volume senders rather than at the dashboard. Everything between those releases is search-oriented content built around deliverability anxiety, plus independent ranking results used as proof.
◆Prediction
On the pattern of the June release, further API work on sending at scale is the most likely next product entry; the intervening posts will stay educational.
