Who this is built for.
Three motions, same infrastructure. Pick the one closest to yours.
Founder-led sales
You sell your own product. The signature is your name. Replies hit your inbox. 1 domain, 5 mailboxes, 1.5K sends/month — runs about $30/mo.
PlaybookAgency outbound
Run outbound for 5–50 clients from a single login. Each client tenant has its own domains, mailboxes, sequences, and wallet. White-label friendly.
PlaybookRevOps + SDR teams
3+ SDRs, scaling to 50K+ sends/month. Per-domain pools by ICP, webhook-first CRM integration, per-mailbox reputation visibility your tool stack hides today.
PlaybookSame job. A fraction of the bill.
Move the sliders. Numbers update live against published Smartlead + Mailwarm pricing. No per-seat fees on our side — invite the whole team.

Add as many teammates as you want — there are no per-seat fees on BoomSauce. Competitor pricing is mid-tier published rates as of 2026-04-29 (Smartlead Basic $94/50K, Mailwarm $79/mailbox). If you also pay Apollo or ZoomInfo for prospecting that's a separate layer — we don't replace it.
Four steps to your first reply.
Pull a list, wire a domain, run warmup, send. Roughly 30 minutes of configuration, then a 30-day warmup window before production volume.
Find the leads
$0.10/contact. Describe your ICP in plain English ("operations directors at logistics companies in Texas, 50–200 employees") and pull verified work emails with title, location, and revenue band attached.
Add a domain
$25/year for a fresh one — registration + DNS + SPF/DKIM/DMARC + 5 mailboxes + a free 1-page website. Or bring your own domain free; we wire DNS while you keep the registrar.
Warm it up
$0.25 per 50-email warmup block on our private peer-to-peer warmup network. 30-day ramp to production volume. Real human inboxes, not synthetic traffic.
Send + reply
$1.50 per 1,000 sends, or AI 1:1 written-per-contact campaigns priced by tier. Every first email is plain, human, and designed to get a reply — no links, no CTAs, no images.
The tools aren’t the problem.
The playbook is.
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.
- Tiered plans that gate features on day one
- Customers handed a list of DNS records to configure alone
- Warmup sold separately or not offered at all
- First emails shipped with links, images, and trackers
- Replies scattered across individual mailbox inboxes
- Unused prepaid credits forfeited on cancellation
- Lead search and AI 1:1 writing live inside the same wallet
- Pay-as-you-go wallet with no minimum commitment
- Full domain setup — DNS, authentication, mailboxes, and website
- Warmup included as a first-class product, priced per mailbox
- Zero links on first emails, enforced by the platform
- Unified conversation inbox across every mailbox and domain
Six principles the platform enforces.
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.
Replies are the metric
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.
No links on the first send
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 on a private network
Warmup runs through a private peer-to-peer network of real mailboxes that generate real engagement signals. No synthetic traffic, no public warmup pools.
Managed domains, end to end
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.
Usage-based billing
One wallet drives the whole account. No tiered plans, no monthly minimum, no long-term contract. Unused balance is refundable on request.
Verified volume accounts
Accounts requesting high-volume infrastructure undergo identity verification before provisioning. This protects deliverability across the platform for every customer.
A rate card, not a subscription.
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.
Registration + DNS + SPF/DKIM/DMARC + free 1-page website. Or bring your own domain free — we wire DNS, you keep the registrar.
Per mailbox, billed daily (~$1/month). Keeps it provisioned, reachable, and receiving replies.
Sold in 50-email blocks. Private warmup network — real humans, real engagement.
Metered per email. Negotiated rates for 1M+/month — contact sales.
Enterprise volume. Accounts requiring 50+ domains or sustained volume above 1,000,000 emails per month are provisioned after identity verification and a brief intake call. Custom pricing available. Contact sales →
Signup is free. Fund your wallet to purchase a domain and start sending.
Now works for teams
Invite your ops, your agency, your assistant. One wallet, shared control, scoped permissions. Switch between accounts with one click when you run more than one.
Owner, Admin, Member
Owners manage billing and the team. Admins handle everything else. Members send and read. Destructive actions are gated per role.
One email, they're in
Enter a teammate's email, pick a role, click send. They get a signed link, sign in with Google, and land on your team's dashboard.
Manage several accounts
Agencies and operators running a portfolio: your email can belong to any number of accounts. The tenant switcher is in your sidebar.
Got an engineer? Wire it into your stack.
Full REST API, a typed Node SDK on npm, and signed webhooks for reply / bounce / unsubscribe events. Push every reply into your CRM without a Zap. If you don't have an engineer — ignore this; the dashboard does everything you need.
Email that reads like a person wrote it.
Built for teams that measure success in replies, not opens. Usage-based infrastructure, reply-first by default, deliverability handled end to end.
