Why your emails aren't landing

Missing authentication

Without proper SPF, DKIM, and DMARC records, email providers treat your messages as suspicious. You're failing the first filter before anyone sees your subject line.

Sending from your primary domain

Cold email from your main company domain puts all your business email at risk. One spam complaint can tank deliverability for your entire org.

No warmup process

New domains and mailboxes need a warmup period. Blasting 500 emails on day one is a fast way to get blacklisted before you even start.

No visibility into placement

Open rates don't tell you where emails land. You could have a 15% open rate and still be hitting spam for 60% of your list. Seed testing reveals the truth.

The setup

Full-stack deliverability

Every layer of the email infrastructure, configured and monitored.

01Domains

Dedicated sending domains

We register and configure dedicated domains for cold outreach. Your primary domain stays protected. Each domain gets proper DNS records from day one.

02Auth

SPF, DKIM, DMARC

Full email authentication setup. SPF authorizes your sending servers. DKIM signs your messages. DMARC tells providers what to do with unauthenticated mail.

03Mailboxes

Mailbox configuration

We configure sending mailboxes with proper display names, signatures, and sending limits. Each mailbox warms up independently to build reputation.

04Warmup

Domain warmup protocol

Gradual sending volume increase over 2-3 weeks. Automated warmup emails build domain reputation before you send a single cold email.

05Monitor

Seed list testing

Weekly inbox placement tests across Gmail, Outlook, Yahoo. You get real data on where your emails land, not just open rate guesses.

06Maintain

Ongoing optimization

Domain rotation schedules, blacklist monitoring, and sending pattern adjustments. Deliverability isn't set-it-and-forget-it.

Common questions

Why are our cold emails going to spam?

Usually it's one of three things: missing authentication records (SPF, DKIM, DMARC), sending from your primary domain (which puts all your company email at risk), or no warmup process. We fix all three.

What does the setup include?

Dedicated sending domains, full DNS authentication (SPF, DKIM, DMARC), domain warmup schedule, mailbox configuration, seed list monitoring, and weekly inbox placement reports. The whole stack.

How long does deliverability setup take?

DNS configuration and mailbox setup take about a week. Domain warmup runs 2-3 weeks after that. You're fully operational in about a month, but we start monitoring from day one.

Will this protect our primary domain?

Yes. We set up dedicated sending domains so your cold outreach never touches your primary company domain. If something goes wrong with cold email, your regular business email stays clean.

What's seed list monitoring?

We send test emails to a network of mailboxes across Gmail, Outlook, Yahoo, and others. Then we check where they land: inbox, spam, or promotions. That gives us a real inbox placement rate, verified weekly.
