More inboxes = more emails sent = more meetings.
Setting everything up yourself takes weeks.
With this offer, you skip all setup and start sending cold emails in minutes.

You can choose domains inside and once claimed, you can let them forward to your primary domain.
You avoid the tech hassle — no domain purchases, no DNS records, no SPF/DKIM/DMARC, no warmup period. You also save hundreds in domain + inbox costs. We handle it all.
Perfect for agencies, freelancers, SaaS founders, lead gen teams, or anyone wanting to scale cold outreach fast — either to test cold email or add volume without tech setup or domain costs.

We maintain our own cold-email-optimized infrastructure. The inboxes are warmed and tested for 95–100% deliverability. Just follow best practices we provide (no spammy copy, avoid links, etc.).
We recommend sending up to 30 cold emails + 20–30 warmup emails per inbox per day to maintain high deliverability. If your sending tool doesn't have integrated warmup functionality, we can continue to warm them up for you.
With 20 inboxes, you can reach 2,000–5,000 prospects per month, depending on how many follow-ups you include.
$99/month for 20 pre-warmed inboxes. You can upgrade anytime for more inboxes.
No free trial, but we do offer a guarantee. If you don’t see 95–100% deliverability (verified via an inbox testing tool of your choice like Mailreach) while following best practices, we’ll refund you.
