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 retells Cliq 7.0 as an AI story, and lets customers pick whose model tells it.
Cliq 7.0 landed on August 19 as a same-day cluster of five posts, headlined by Cliq Mini — the old chat widget repositioned as communication that travels with the user across CRM, help desk and project apps, with picture-in-picture carrying calls along. Two weeks later Zoho published a narrative recap of the same release framed around AI: MCP-driven agents answering questions about a channel, live meeting transcripts, visible slot availability in event scheduling, and a Deluge Zia bot that generates automation scripts from a plain-language description. The recap also adds a genuinely new admin option — Gemini, Cohere, DeepSeek and Claude selectable alongside Zoho's own Zia.

◆ 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 retells Cliq 7.0 as an AI story, and lets customers pick whose model tells it.
◆ Current state
Cliq 7.0 landed on August 19 as a same-day cluster of five posts, headlined by Cliq Mini — the old chat widget repositioned as communication that travels with the user across CRM, help desk and project apps, with picture-in-picture carrying calls along. Two weeks later Zoho published a narrative recap of the same release framed around AI: MCP-driven agents answering questions about a channel, live meeting transcripts, visible slot availability in event scheduling, and a Deluge Zia bot that generates automation scripts from a plain-language description. The recap also adds a genuinely new admin option — Gemini, Cohere, DeepSeek and Claude selectable alongside Zoho's own Zia.
◆ Where it's heading
Cliq's recent moves point the same way from opposite ends: the MCP server made it an endpoint agents drive, and 7.0 makes it a surface embedded inside sibling Zoho apps. Both reduce the case for opening Cliq as its own window. The model-provider toggle is the newer thread and cuts against Zoho's usual posture of shipping its own AI — it concedes that customers now arrive with a model preference. Note the feed's shape: 7.0 is being re-announced from several angles, so a post's date says little about when the capability shipped, and multimedia summaries are described as in progress rather than available.
◆ Prediction
Expect the provider list in the admin panel to become the standard pattern across Zoho apps rather than staying a Cliq setting, since the same Zia surface exists suite-wide. Whether multimedia summaries ship as described is the open item — the post commits to the direction without dating it.
