Mamba Labs builds GTM signal enrichment tools published as Apify actors and MCP servers. Every tool returns flat, Clay-ready JSON per company, priced per result with no subscriptions.

What is the GTM Suite?

The GTM Suite is an all-in-one MCP server that bundles fifteen Mamba Labs tools into a single install. It covers identity resolution, signal detection, ICP scoring, and sequencer push from one endpoint.

USE CASE:

Deliverability for logistics companies

Here is how deliverability for logistics companies actually gets done, what it costs each way, and where each way stops working. We are Mamba Labs, we build Apify actors, and Domain Deliverability Checker is the one that does this for logistics companies.

What is actually going wrong

Logistics companies and deliverability: the answer is public, scattered, and nobody has time to collect it. Logistics companies run on margins thin enough that any software purchase has to pay for itself in a quarter, and deliverability inherits that. What catches people out on logistics companies, deliverability included: a freight forwarder, a carrier and a broker all describe themselves as logistics. Domain Deliverability Checker carries 1 ready made setup for deliverability on logistics companies.

Why it matters

Sending to logistics companies does not change your authentication, and it does change how quickly a complaint turns into a block.

Doing it end to end

Start with one of logistics companies you already know, so a wrong deliverability answer is obvious rather than plausible.
Run Domain Deliverability Checker across your list of logistics companies, which carries 1 ready made setup for deliverability.
Read ten rows of deliverability on logistics companies by hand before you trust the rest of the list.

Traditional Search Tools

The operator licence register, for logistics companies. Free, and it says which of the three you are looking at.
MXToolbox. The tool most people already use, and it is genuinely good for one domain at a time. It is a web form, so checking 40 sending domains means 40 visits.
Google Postmaster Tools. The only place you see what Gmail thinks of your reputation, and it is free. It covers Gmail, it needs domain verification, and it says nothing about the other half of your list.
Your sequencer's own health check. Instantly and Smartlead both ship one. They check the domains you send from, which is the point, and they will not check a domain you have not connected yet.
Read the DNS yourself. dig the SPF, DKIM and DMARC records for the sending domain, then check it against the public blocklists one at a time. Fifteen minutes per domain if you know what you are looking at.
