Our Story
Mailfrog was born inside Avention Media, a B2B data company with 10+ years of experience delivering high-quality data to 10,000+ customers worldwide.
After supplying 50M+ B2B records and running 1,500+ campaigns for clients, we built Mailfrog to bring data and outbound execution into one platform.

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.
