What is SMTP2GO?

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.

What is Zoho Cliq?

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.

Deliverability blogging with one real API release buried in the run

◆ 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.

Zoho Cliq 7.0 bets on AI conversation summaries and Neat hardware to close the gap with enterprise messaging platforms

◆ Current state

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.

◆ Where it's heading

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.

◆ Prediction

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.
