What is Gumloop?
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
Gumloop ships a numbered release every few days, and since 12.0's Agent Browser each one widens what agents can reach and govern. 12.4 lets the Gumball agent use several accounts for the same app, share artifacts, skills and agents across teams, and set up custom MCPs for apps without a native connector. It also adds per-model spend and BYOK savings reporting in Insights, plus email search in audit logs, after 12.3's model-gated triggers and new frontier models.
What is MailerLite?
MailerLite ships two-way Shopify sync and an AI agent skill while building out its editor with code blocks and video.
MailerLite is shipping steadily on two tracks: deepening its e-commerce integrations (two-way Shopify sync, product variant targeting for purchase triggers) and expanding the editor's capability surface (code blocks, video blocks, full color picker, copy-paste across all automation steps). The ChatGPT directory listing and the email marketing skill for AI agents signal an early positioning in the AI tooling ecosystem.
Gumloop vs MailerLite: editorial side-by-side
Gumloop
6.3MKT AUTO
Gumloop 12.4 lets its agent build custom MCPs for apps the platform doesn't support.
◆ Current state
Gumloop ships a numbered release every few days, and since 12.0's Agent Browser each one widens what agents can reach and govern. 12.4 lets the Gumball agent use several accounts for the same app, share artifacts, skills and agents across teams, and set up custom MCPs for apps without a native connector. It also adds per-model spend and BYOK savings reporting in Insights, plus email search in audit logs, after 12.3's model-gated triggers and new frontier models.
◆ Where it's heading
The platform is moving from workflow automation to a managed agent runtime: agents browse, own credentials, manage files and skills, and now extend their own integrations through custom MCPs. Cross-team sharing and spend reporting point at larger organizations, with credit cost kept a visible part of the product.
◆ Prediction
Expect more organization-level controls for shared agents and custom MCPs, such as approvals or admin policies, given the new sharing and audit-log search. The entries don't show pricing changes for agent-built integrations.
MailerLite
6.3MKT AUTO
MailerLite ships two-way Shopify sync and an AI agent skill while building out its editor with code blocks and video.
◆ Current state
MailerLite is shipping steadily on two tracks: deepening its e-commerce integrations (two-way Shopify sync, product variant targeting for purchase triggers) and expanding the editor's capability surface (code blocks, video blocks, full color picker, copy-paste across all automation steps). The ChatGPT directory listing and the email marketing skill for AI agents signal an early positioning in the AI tooling ecosystem.
◆ Where it's heading
The two-way Shopify sync is the clearest signal of where this is heading: MailerLite wants to be the authoritative subscriber record, not just a send layer on top of Shopify data. The AI agent skill points toward MailerLite becoming accessible to AI coding agents — a channel that could drive meaningful developer adoption if other integrations follow the same pattern.
◆ Prediction
Variant-level purchase triggers will roll out to Shopify, WooCommerce, and BigCommerce, and the two-way sync will likely expand to other e-commerce platforms. The AI agent skill will probably be expanded to cover more campaign operations as AI coding tools become more widely used.
