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:

The real work behind deliverability for insurtech companies

Here is how deliverability for insurtech companies actually gets done, what it costs each way, and where each way stops working. Mamba Labs writes Apify actors for work like this, and Domain Deliverability Checker is the one that reads insurtech companies.

Where this starts

Insurtech companies skew deliverability, for a reason specific to them. Start from this: insurtech companies are brokers, carriers or software pretending to be one of the two, and the label rarely says which, and deliverability follows. Know this about insurtech companies before any deliverability: a broker and a carrier look identical from the homepage and buy nothing alike. Domain Deliverability Checker carries 1 ready made setup for deliverability on insurtech companies.

Why anyone bothers

A single blocklist entry costs you a week of sending to insurtech companies and gives no notice at all.

The method

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

Traditional Search Tools

The regulator's firm register, for insurtech companies. Free, and it separates the broker from the carrier in one lookup.
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.
