Loops: User reviews & features

Loops is an email platform for SaaS teams — the positioning stated on its own homepage at loops.so, which we verified at source in August 2026. It is one of the newer brands in the catalog, and our measured demand figure for it is a floor: the word "loops" is generic enough that brand searches cannot be cleanly separated from unrelated queries. It is cataloged at tier 3 accordingly. Pricing at our normalization volumes has not been captured, so no price level is assigned to this entry yet.

Measurement status

Not yet tested

Loops has not yet been through our seed-list placement test. We publish measured deliverability data only — never estimates.

Loops and AI agents

91/100AI-native

Official MCP server · hosted, connect by URL

AI agents and assistants can work with Loops directly through Loops MCP server: Streamable HTTP + OAuth at https://mcp.loops.so: contacts, mailing lists, events, transactional sends, workflows and other API operations (search/describe/execute/teams tools)

Scored 0–100 from public evidence: an official MCP server weighs most (40, +5 when hosted), then official agent skills, AI assistant apps, AI-friendly docs and built-in AI features. "Not found" means we couldn't locate it on Loops's public pages or the official MCP registry, not that it can't exist. This is context, never part of the Deliverability Score.

Frequently asked questions

What is Loops?

Loops is an email marketing service in the InboxRatio catalog. Its regional focus is Global.

Does Loops document its deliverability capabilities?

Loops documents 12 of the 17 deliverability capabilities we audit every vendor for (authentication help, IP management, list hygiene, reputation tooling). This audits what the vendor documents — it is separate from our measured Deliverability Score, and undocumented items are themselves a signal. How we read vendor claims.

What do users say about Loops?

Across 1 reviews on G2, Loops averages 4.0/5, with Trustpilot counting for half of the average. User ratings are shown as context only — never part of our measured Deliverability Score.

Has Loops' deliverability been tested by InboxRatio?

Not yet — Loops is in the queue for Cycle 0, our first seed-list test cycle across the whole catalog. We publish measured inbox-placement results only after a completed cycle, so this profile carries no Deliverability Score until then. How we test.

What are the main Loops alternatives?

From our catalog, the closest alternatives are Acumbamail, EmailOctopus and Benchmark Email — services sharing Loops' primary category (email marketing), selected by a neutral catalog rule, never hand-picked.
