Free · Run for you
Find out which of your target accounts will never see your cold email.
Large companies put security gateways like Proofpoint and Mimecast in front of their inboxes. If a chunk of your market sits behind one, your open rates are lying to you. Send us your target domains and we'll map exactly who is behind what, free.

The report
Your market, split by what guards the inbox.
Provider split.
What share of your target accounts runs Google Workspace, Microsoft 365, or something else.
Gateway detection.
Which accounts sit behind a secure email gateway: Proofpoint, Mimecast, Barracuda, Cisco IronPort.
What it means.
A short read on how the split should change your sending: volume, segmentation, and which accounts need a different channel entirely.
How we know
It's in the DNS. Most teams never look.
Every domain publishes which servers receive its email. Data vendors sell this field. We read it directly, at the scale of your whole target list, and interpret what it means for outreach. No login to your tools, no pixel, no access to anything private.

FAQ
Questions, answered.
Is this safe to share?
You're sharing company website domains, which are public. No contact names, no emails, no CRM access. We check DNS records anyone can query.
What do you do with my list?
We run the report and follow up about it. The list is not sold, shared, or used for anything else.
Why does this matter for outreach?
A gateway between you and the buyer filters more aggressively than normal spam filtering. If a third of your market sits behind one, average open and reply rates are not telling you why. Knowing the split tells you where email works and where you need the phone, LinkedIn, or ads instead.
Can you fix the accounts behind gateways?
There is no trick that beats a gateway. What works is treating those accounts differently: tighter volume, better infrastructure, and other channels. That is part of what we run for clients.
