Free AI interview

You give us your website and talk to PROXY for about ten minutes. It reads your site, asks about your offer and who you want to reach, and writes a business brief — your goal, your offer and your audiences. You approve and edit it before anything else happens. The interview and the brief are free, and you never need a card or a sales call to get them.

AI Outreach Playbook — $500

The playbook is consulting-grade research written for your business alone. A team of specialist AI agents works on it for more than two hours: a researcher that reads your site and 50–80+ public sources, a copywriter that writes every email, and a targeting stage that turns each audience into company and role searches.

What you receive:

• Who to reach — every audience worth reaching, the evidence behind it and an estimate of its size.
• What to say — an opener and two follow-ups written for each audience.
• How to find them — the exact company-description and job-title searches, often tens of thousands of them.

The launch price is $500 through 31 December 2026; after that it is $1,000. It is a one-time purchase: keep it, export it and use it with any tool or team, or have SLSBMB run it with the Sending Engine. The complete Revopush playbook is published as an example.

AI Contacts — $0.10 per verified email

Describe the people you need as one sentence — a company type and a job title, such as "German B2B SaaS — Heads of Sales". We turn it into precise filters across 536M+ professionals at 105M+ companies and show ten real matches and the full count for free.

• You order 50 to 3,000 verified emails per search, or every match when fewer than 50 people fit.
• You pay $0.10 per unique deliverable business email we actually find. Duplicates are not charged twice, and no result means no charge.
• The maximum for your order is reserved first; anything not used returns to your SLSBMB AI wallet for later orders.
• Business emails only. Phone numbers are not included.

Sending Engine — from $800 a month

The Sending Engine runs your playbook on infrastructure we buy and operate for you: separate sending domains (never your own domain), inboxes, authentication, a 21-day warmup, verified contacts, the campaigns themselves and reply handling. There is one monthly budget. The more you put in, the less each email costs.

Every sending domain carries four inboxes; each inbox sends up to 15 campaign emails per sending day; and each new person receives an opener and up to two follow-ups. Contacts for the month are included in the budget — the engine's new people a month, rounded up to the next 100 (900 at the $800 entry) — so a Sending Engine purchase never charges contacts twice.

Capacity at full speed, after warmup and ramp-up:

Reference forecast: 22 sending weekdays at mature capacity, with one opener and two follow-ups. Actual purchases follow the paid calendar, deliverability and remaining campaign work; these figures are not monthly contact limits.

Below $3,000 the budget moves one sending domain at a time; from $3,000 it moves in $1,000 steps up to $100,000 with no fixed tiers in between. The calculator on the home page shows every step.

How billing works

• No setup fee. The $800 entry is the first month's Sending Engine budget, not an onboarding charge.
• Billing starts at payment. Month one pays for the domains and inboxes and about 21 days of warmup from the moment the inboxes exist; first campaign emails go out around day 22, then volume ramps up to full capacity.
• One month at a time. Each month runs from your payment date. Your card is only kept for renewals if you explicitly agree, and you can turn renewals off in SLSBMB AI Billing; the paid month runs to its end.
• Replies take time. For planning we assume about 2% of campaign emails get a reply at full capacity — at $800 that is about 53 replies a month — but people answer days or weeks later, often only to a follow-up, so plan on that level from the start of month three. Your workspace reports activity and replies audience by audience, and the targeting controls let you shift audience priorities, company countries and the roles in new contact purchases.

What the same budget buys at an agency

Most B2B cold email agency programs cost $3,000–$7,000 a month on retainer, plus $500–$2,000 a month for domains, mailboxes, data and warmup, a $1,500–$5,000 onboarding fee and usually a three-month minimum, on a typical setup of 6–15 inboxes. SDR teams and campaign pods run from about $8,000 to $30,000 a month. At $3,000 the Sending Engine runs 40 inboxes and 13,200 campaign emails a month; at $8,000, 244 inboxes; at $15,000, 664 — with contacts, infrastructure and warmup included and no setup fee.

Payment methods

Card (with Apple Pay or Google Pay where supported) through Airwallex hosted checkout, bank wire, or crypto through NOWPayments. All three are equal options; payment always happens on the provider's hosted page or by invoice, never on our landing page.

Refunds

Payments are final and non-refundable, except for the limited corrections and non-excludable legal rights described in the Refund, Cancellation and Suspension Policy. Returning an unused AI Contacts reservation to your wallet is part of normal settlement, not a refund. SLSBMB is sold for business and professional use only.

What is not included

• Sending from your own company domain. We never do it.
• Phone numbers or private email addresses.

Frequently asked questions

Is there a setup fee?

No. The Sending Engine has no setup fee; the $800 entry is your first monthly budget. The first month pays for the infrastructure and its 21-day warmup.

Is there a long-term contract?

No. The Sending Engine is paid one month at a time from your payment date, and renewals can be turned off in SLSBMB AI Billing.

Do I have to buy everything together?

No. The free interview, the AI Outreach Playbook, AI Contacts and the Sending Engine can each be bought separately. Many people start with the free interview and the playbook.

How many contacts does the Sending Engine include?

Verified contacts are included. We buy enough for the actual sending calendar after accounting for existing contacts and remaining follow-ups. For comparison, 22 sending weekdays at mature capacity imply about 880 new people at $800, 4,400 at $3,000 and 44,000 at $10,000 with three-email sequences. These are reference forecasts, not purchase caps; contacts are not charged again on top of the Sending Engine budget.

When do the first emails go out?

About day 22 after payment. New inboxes need roughly three weeks of warmup before cold email lands in the inbox instead of spam, and sending starts once the full set of inboxes is connected and every launch check is clear.

Can I pay with crypto?

Yes. Card, bank wire and crypto are equal payment options.
