A cold email agency builds the infrastructure, lists and copy that get your emails into the inbox and turn replies into booked meetings. KNK Outbound runs the whole stack for US B2B teams: dedicated sending domains, warmed inboxes, signal-driven lists and AI personalization, done for you.

Why most outbound fails

Your cold email isn't a copy problem.
It's an infrastructure problem.

The best email in the world does nothing from the spam folder. Deliverability and targeting decide everything.

Sending from your main domainNo separate domains or warmup, so you torch your reputation and land in spam.
No SPF, DKIM or DMARCSkip authentication in 2026 and your campaigns sink before anyone reads them.
Bought lists, no verificationHigh bounce rates flag your domain and quietly wreck deliverability.
One email, no follow-upMost replies come from follow-ups, so a single send leaves money on the table.
Why it compounds

The KNK Engine

Signals enter. Three channels process them. One core compounds the learning, and qualified meetings come out the other side.

FAQ

Frequently asked questions

What does a cold email agency actually handle?

Everything between 'we should do cold email' and a booked meeting: separate sending domains and inboxes, SPF, DKIM and DMARC setup, warmup, verified signal-driven lists, copywriting, sending, reply handling and booking. You never risk your main company domain.

Is cold email still legal and does it still work in 2026?

Yes. B2B cold email is legal in the US under CAN-SPAM when done right (accurate sender, opt-out honored). It still books meetings when it is signal-driven and lands in the inbox. What died is spray-and-pray from unwarmed domains, and that is an infrastructure problem we solve first.

How do you keep our emails out of spam?

Dedicated lookalike domains so your main domain stays clean, proper authentication, weeks of warmup before sending, conservative per-inbox volume, verified lists to keep bounces near zero, and copy without spam triggers. Deliverability is monitored continuously, not checked once.

How many emails do you send and when do meetings show up?

Volume scales with warmed capacity, typically hundreds of targeted emails per day across multiple inboxes rather than blasts. Campaigns are usually live within about 21 days, and we guarantee 15 qualified meetings in your first 90 days or we work free.
