Our Story
Mailfrog was born inside Avention Media — a data-driven B2B marketing company with over a decade of experience helping enterprise brands reach the right buyers, at the right time.
After years of running outbound campaigns for clients, the Avention Media team kept running into the same wall: great data trapped in one tool, great execution locked in another — with an invoice for each. So we built the platform we always wished existed.
Mailfrog is Avention Media's dedicated outbound engine — combining proprietary data infrastructure with campaign execution in one unified product. The B2B expertise that powered hundreds of client campaigns is now available to every growth team.

Enterprise B2B data & demand generation — powering global outbound since 2014.
ICP-First outbound platform — custom data engine meets unlimited campaign execution.
The Structural Flaw in Outbound
The traditional outbound market is broken. Most platforms separate "data" from "execution"—forcing you to buy decaying, one-size-fits-all lists from one vendor, only to upload them into software that gates your campaign features behind arbitrary pricing tiers.
Data providers and execution tools don't talk to each other, resulting in lost fidelity and gated features. It is a model built for volume, not context.
We built a unified intelligence layer where your Ideal Customer Profile (ICP), your custom data, and your campaign execution converge in one place.
1. The Blueprint
Stop retrofitting your strategy to match whatever data is available. Inside Mailfrog, your ICP is a first-class asset that drives everything else.
2. The Fuel
High-value B2B audiences are fragmented and niche. Our on-demand engine builds a fresh database exclusively for your ICP parameters.
3. The Engine
Generic AI creates noise and kills trust. Mailfrog's AI feeds on your deeply defined ICP, generating messaging that drives actual replies.
4. The Execution
We never lock multi-step sequences behind gated plans. Total campaign freedom with zero feature gating and no step limits.
By bridging the gap between data generation and campaign execution, your entire outbound system lives under one roof.
