A side-by-side editorial comparison of SMTP2GO and Zoho Cliq — release velocity, themes, recent moves, and the top alternatives to consider.
SMTP2GO vs Zoho Cliq: at a glance
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 is opening its bot platform to AI coding agents through MCP tools.
Cliq 7.0 shipped in August with AI summarisation, a developer platform refresh and Cliq Mini embedded across Zoho apps. September added reworked guest access, Cliq Rooms on Neat hardware and per-role subscription plans. In October Cliq published MCP tools for its developer platform, so automations can be generated with an AI coding assistant instead of written by hand.

SMTP2GO
5.0COMMS
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
6.3COMMS
Zoho Cliq is opening its bot platform to AI coding agents through MCP tools.
◆ Current state
Cliq 7.0 shipped in August with AI summarisation, a developer platform refresh and Cliq Mini embedded across Zoho apps. September added reworked guest access, Cliq Rooms on Neat hardware and per-role subscription plans. In October Cliq published MCP tools for its developer platform, so automations can be generated with an AI coding assistant instead of written by hand.
◆ Where it's heading
Cliq is turning into the messaging layer of the Zoho suite and widening its reach: other Zoho apps, meeting-room hardware, external guests, and now AI agents that write its automations. The developer platform keeps lowering the cost of building bots and workflows, first through 7.0's low-code tooling and now through MCP. Pricing is moving the same way, with role-based plans meant to put more of each company on Cliq.
◆ Prediction
Expect more of the Cliq developer platform (bots, handlers, widgets) to be exposed through MCP. The entries don't show whether AI-assisted building will be priced separately.
