About SMTP2GO
A blog-heavy feed masks the real signal: API upgrades for high-volume senders
SMTP2GO's tracked feed is dominated by marketing and educational blog posts — provider listicles, deliverability guides, and explainers — which makes actual product direction hard to read from this source. The one concrete product move in the recent window is a batch of API enhancements: scheduled sends, higher throughput, and more efficient large-batch sending. The company is investing heavily in deliverability content marketing around its core relay product.
