Superhuman
Superhuman rebuilt its mobile apps and wired every inbox into AI assistants — the email client is becoming a suite.
A side-by-side editorial comparison of SMTP2GO and Zoho Cliq — release velocity, themes, recent moves, and the top alternatives to consider.
Deliverability blogging with one real API release buried in the run
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.
Zoho Cliq 7.0 bets on AI conversation summaries and Neat hardware to close the gap with enterprise messaging platforms
Zoho Cliq is mid-cycle on its most substantial release in years. Cliq 7.0 (August 2026) introduced AI-powered thread summaries, automatic task extraction from conversations, voice transcription with AI notes, and a redesigned developer platform. The guest user feature was overhauled for external collaboration, and the product now runs natively on Neat conferencing hardware — moving from software into physical meeting rooms.

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.
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.

Cliq is running a dual-layer play: embed Zia AI deeply enough in conversations that task tracking happens inside the messaging layer rather than alongside it, while simultaneously opening to the agentic ecosystem through MCP integration and a more accessible developer platform. The Neat hardware integration points toward a longer-term push for enterprise room-system budgets, typically owned by IT rather than team leads.
Expect deeper Zia integration within the Cliq developer platform — bots triggered by conversation context rather than scheduled tasks. The MCP path suggests Cliq is positioning itself as a target for external AI agents, not just a source of data for them.
