Threema vs SMTP2GO
A side-by-side editorial comparison of Threema and SMTP2GO — release velocity, themes, recent moves, and the top alternatives to consider.
Threema vs SMTP2GO: at a glance
What is Threema?
Threema's feed mixes privacy editorials with a trickle of Work-focused feature releases
Threema's recent feed is dominated by privacy commentary and campaign posts (system-level anonymity, #DeleteWhatsAppDay, a cyberattack analysis), interleaved with a few genuine product updates aimed at its business tier — availability status and a survey feed. Signal-to-noise is low: most entries are editorial, not release notes.
What is 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.

Threema's feed mixes privacy editorials with a trickle of Work-focused feature releases
◆ Current state
Threema's recent feed is dominated by privacy commentary and campaign posts (system-level anonymity, #DeleteWhatsAppDay, a cyberattack analysis), interleaved with a few genuine product updates aimed at its business tier — availability status and a survey feed. Signal-to-noise is low: most entries are editorial, not release notes.
◆ Where it's heading
Where there are real features, they cluster around Threema Work and OnPrem — availability status, screenshot prevention, DualLock — signaling continued focus on the enterprise and B2B segment over consumer feature velocity. The consumer narrative is carried by privacy positioning rather than shipping.
◆ Prediction
Expect more Threema Work and OnPrem enterprise features plus continued privacy-advocacy content; consumer-facing functional releases look infrequent. Several entries are blog posts, which limits confident roadmap reads.

A blog-heavy feed masks the real signal: API upgrades for high-volume senders
◆ Current state
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.
◆ Where it's heading
Stripping out the blog noise, the product itself is trending toward scale — the API work targets high-volume, programmatic senders who need scheduling and throughput headroom. The rest of the feed is positioning and top-of-funnel education, not shipping. Product signal from this source is thin and should be read with caution.
◆ Prediction
Expect continued API and deliverability tooling aimed at high-volume senders; the blog-dominated feed offers little additional product signal to forecast from.
