BoomSauce is email infrastructure built for replies. First-touch messages go out as plain, human text — no links, no images, no trackers — because the only metric that matters is whether the recipient writes back. Usage-based pricing, deliverability handled end to end.
Roughly 30 minutes of configuration, then a 21-day warmup window before production volume.
$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.
$0.25 per 50-email warmup block on our private CheddarInbox network. 21-day ramp to production volume. Real human inboxes, not synthetic traffic.
$1.50 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.
Standard cold email advice — links, CTAs, images, calendar invites on the first touch — is the primary driver of spam-folder placement. The fix is structural, not a better subject line.
Email is a conversation medium. The send gates, pricing model, warmup network, and account verification all enforce that — so the right behavior is the default behavior.
Open rates are vanity. Reply rates are the business. Every product decision — send gates, templates, inbox design — is oriented toward a response from a real person.
Hyperlinks, images, and tracking pixels are the fastest path to the spam folder. BoomSauce strips them from every first-touch email. Once a recipient replies, standard formatting is available on follow-ups.
Warmup runs through CheddarInbox — a private peer-to-peer network of real mailboxes that generate real engagement signals. No synthetic traffic, no public warmup pools.
Domain registration, DNS, SPF, DKIM, DMARC, five mailboxes, and a one-page website are configured in a single flow. No hand-off, no DNS copy-paste, no gaps in your footprint.
One wallet drives the whole account. No tiered plans, no monthly minimum, no long-term contract. Unused balance is refundable on request.
Accounts requesting high-volume infrastructure undergo identity verification before provisioning. This protects deliverability across the platform for every customer.
Fund your wallet once. Everything meters against it — domains, mailbox hosting, warmup blocks, outbound sends. No tiers. No minimums. Top up when you need more.
