What is Chatwoot?
Chatwoot retires Captain V1 and rebuilds its AI assistant as a structured, per-assistant behavior system.
Chatwoot is in the middle of a significant architectural transition for its AI assistant layer. The original Captain V1 (free-form instructions) is being retired in the next self-hosted release in favor of a structured model with scenarios, response guidelines, guardrails, and a testing playground. Cloud users are already on the new system. Alongside this, two substantial releases expanded Captain's control surface: per-assistant custom tools, inactivity handling, and audience/schedule targeting. WhatsApp BSUID support and improved call recording controls round out a busy month in the communications layer.
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.

Chatwoot retires Captain V1 and rebuilds its AI assistant as a structured, per-assistant behavior system.
◆ Current state
Chatwoot is in the middle of a significant architectural transition for its AI assistant layer. The original Captain V1 (free-form instructions) is being retired in the next self-hosted release in favor of a structured model with scenarios, response guidelines, guardrails, and a testing playground. Cloud users are already on the new system. Alongside this, two substantial releases expanded Captain's control surface: per-assistant custom tools, inactivity handling, and audience/schedule targeting. WhatsApp BSUID support and improved call recording controls round out a busy month in the communications layer.
◆ Where it's heading
Chatwoot is shifting Captain from a chatbot add-on into a proper automation layer with auditable, testable behavior. Per-assistant tool isolation, audience segmentation, and schedule-based availability bring it closer to the model used by Intercom Fin and Zendesk AI. The V1 retirement removes a backward-compatibility constraint that was slowing this transition. The playground — which lets admins test assistant configurations before saving — removes the need to test in production, which was the practical barrier to iterating on Captain.
◆ Prediction
The next likely move is a reporting layer for Captain — tracking resolution rates, handoff rates, and scenario effectiveness per assistant. The playground's 'Run details' view (showing which scenario handled a message and which tools ran) is the building block for that kind of analytics.

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.
