BoomSauce is the 1:1 email platform built around replies. Every first email is plain, human, and link-free — because the only thing that matters is whether they write back. Pay-as-you-go. No plans, no minimums, no surprises.
From zero to sending in about 30 minutes of hands-on + 21 days of warmup.
$20/year. We register it, wire DNS + SPF/DKIM/DMARC, spin up 5 mailboxes, and build you a free 1-page website so the domain looks real from day one.
$7.50/mailbox/month on our private CheddarInbox network. 21-day ramp to production volume. Real humans inboxes, not synthetic traffic.
$1 per 1,000 sends. Pay-as-you-go from your wallet. Every first email is plain, human, and designed to get a reply — no links, no CTAs, no images.
Every “sequence” tool shows you to pack email #1 with links, CTAs, images, and calendar invites. That’s what tanks your sender reputation. The fix is the opposite.
Email is a conversation medium. Everything we built reinforces that — from the send gates to the pricing model to the warmup network.
Most email tools measure opens. We measure replies. Every UI decision, every send gate, every template is designed to get a response from a real person.
The reason your cold emails go to spam isn't bad copy — it's the link, the image, the tracking pixel. We strip all of that from first touches. Links unlock once they reply.
CheddarInbox is our own P2P warmup network. When you pay $7.50/mailbox, we route real engagement from real inboxes. Not bots. Not farms.
Buying a domain from Namecheap gets you a domain. Buying one from us gets you a fully authenticated sending domain with 5 mailboxes and a real website at the root.
No tiers, no minimums, no 'upgrade to Pro'. Load credits, pay per domain + mailbox + email. Refund the unused balance anytime (10% fee, no drama).
Enterprise accounts (50+ domains or 1M+ sends) get human review before we provision. Keeps the network clean for everyone and stops us from becoming a spam farm.
Load your wallet, pay for what you use. No tiers, no minimums. Here’s what it actually costs for three common setups.
Registration + DNS + SPF/DKIM/DMARC + 5 mailboxes + free 1-page website.
Opt-in per mailbox. 50 emails/day on the CheddarInbox network. Cancel anytime.
Metered per email. No commitment. Negotiated rates for 1M+/month — contact sales.
Volume? 50+ domains or 1M+ sends/month requires KYC + a sales conversation. We price partner accounts case-by-case and can drop SMTP to $0.50/1K at the right scale.
No credit card at signup. Fund your wallet when you’re ready to send.
Stop sending emails that sound like emails. Start sending emails that sound like a person asked a question and meant it. That’s BoomSauce.
