What is Gumloop?
Gumloop's agent triggers pick up the generic case: any webhook can start a run.
Gumloop builds AI agents and workflows for internal operations. Agents can now be started by a webhook, each with its own URL, so a form submission or an alert from another system kicks off a run carrying its payload — and an agent can be asked to set one up in chat. GLM 5.3 Flash joins the model list, and the release fixes agent chats stalling mid-task and losing work when resumed after an approval.
What is Mailmeteor?
Mailmeteor pushes past simple mail-merge toward AI assistance and serious-sender deliverability.
Mailmeteor is a Gmail-native mail-merge and outbound tool that has spent the last year expanding on two fronts: AI assistance across the mail lifecycle, and deliverability infrastructure for higher-volume senders. Recent releases add a Deliverability Hub for sender-health visibility and Inbox Rotation for spreading campaigns across multiple accounts.

Gumloop
7.5MKT AUTO
Gumloop's agent triggers pick up the generic case: any webhook can start a run.
◆ Current state
Gumloop builds AI agents and workflows for internal operations. Agents can now be started by a webhook, each with its own URL, so a form submission or an alert from another system kicks off a run carrying its payload — and an agent can be asked to set one up in chat. GLM 5.3 Flash joins the model list, and the release fixes agent chats stalling mid-task and losing work when resumed after an approval.
◆ Where it's heading
This completes a trigger family that has been filling in for months: Outlook mail and calendar in August, Monday.com board activity a week later, and now the generic webhook that covers everything without a purpose-built connector. The reliability fixes in the same release point at the same goal — unattended runs are only useful if they finish. Agent management is also getting more self-service, with activity shown per agent and evaluation criteria pausable.
◆ Prediction
With a generic inbound trigger in place, the remaining gap is what happens when an unattended run needs a decision, so expect more work on approvals and on recovering runs that stall mid-task.
Mailmeteor
3.8MKT AUTO
Mailmeteor pushes past simple mail-merge toward AI assistance and serious-sender deliverability.
◆ Current state
Mailmeteor is a Gmail-native mail-merge and outbound tool that has spent the last year expanding on two fronts: AI assistance across the mail lifecycle, and deliverability infrastructure for higher-volume senders. Recent releases add a Deliverability Hub for sender-health visibility and Inbox Rotation for spreading campaigns across multiple accounts.
◆ Where it's heading
Two throughlines are visible. AI has grown from a July 2025 writer (Sheets, Gmail, Dashboard) into a January 2026 reply assistant, moving Mailmeteor from 'send campaigns' toward managing the whole conversation. In parallel, deliverability tooling — warm-up bundled into Pro, then the Deliverability Hub and Inbox Rotation — is repositioning the product for 'serious senders' who need sender health and scale, not just personalization.
◆ Prediction
Expect deeper deliverability tooling (reputation monitoring, per-sender analytics) building on the Hub, and continued extension of the AI assistant from replies toward more of the send-and-follow-up loop.
