Guides

The guides

• How to choose an outbound provider — A buyer's checklist for cold email agencies, AI SDRs and outbound services. The questions that reveal real work, the metrics that matter (targeted replies, not opens), the traps in comparing vendors' numbers, why pay-per-meeting and revenue-share deals go wrong, and how to run a fair three-month test.
• What cold email costs in 2026 — Published 2026 prices for every way to run B2B cold email — the tools to do it yourself, done-for-you agencies from $2,500 retainers to $30,000 campaign pods, AI SDR software, an in-house SDR and SLSBMB AI — with what each budget buys and what each quote leaves out.
• Cold email deliverability without risking your domain — The deliverability rules SLSBMB AI runs on — separate sending domains on its own servers and IP addresses, SPF, DKIM, DMARC and MTA-STS, a 21-day warmup, at most 15 campaign emails per inbox per day, smooth sending without bursts or duplicates, verified addresses, one-click unsubscribe and permanent suppression.
• How to calculate cold email ROI — An honest way to tell whether outbound pays for your business. The cost of a useful conversation, a worked example at $800 a month, how small a customer can be at each budget, why cheap replies can be the most expensive, how long to give the channel, and when it's too early for outbound.
• How a cold email sequence works — The structure of every SLSBMB AI sequence — one researched opener and two substantive follow-ups per audience — with real published examples, why follow-ups matter, how long a cold email should be, how to personalize without looking like surveillance, and why no two recipients get the same text.
• Cold email vs LinkedIn, ads, events and calls — How the B2B channels compare for reaching people who don't know you yet. What a LinkedIn or Google Ads lead costs in 2025, what a trade show lead really costs, LinkedIn's limits, WhatsApp's consent rules, and why researched email is the cheapest way to start a conversation with the right person.
• Email warmup: why 21 days, and what real warmup looks like — Why new cold email inboxes must warm up before sending, how long it takes, what separates real warmup from template networks and "pre-warmed" inboxes, and how SLSBMB AI warms every inbox for about 21 days before the first campaign email on day 22.
• The first 90 days, step by step — A timeline from payment to replies: the playbook in a few hours, about 21 days of inbox warmup, first campaign emails around day 22, a gradual ramp, and replies building toward full level from month three.
• How to get your first B2B customers with outbound — A practical distribution plan for founders without a sales team — choose audiences, find the right people, write a short sequence, protect your domain, send at a human pace, and learn from the replies — with costs and timelines.
• Is cold email legal? — When a B2B cold email is allowed in the US (CAN-SPAM), the UK (PECR), France and the EU (GDPR legitimate interest), Canada (CASL), Australia and Hong Kong, why Germany is different, who is responsible for what, and the rules SLSBMB AI builds into every campaign.
• What to do when a prospect replies — The first reply is the most fragile moment in outbound. How fast to answer, how to handle "tell me more", "not now", "come back in three months", "swamped, maybe later" and "talk to my colleague", what to hand over with a lead, and how SLSBMB AI sorts every reply and drafts your answer.
• How to choose who to target with cold email — Why one ideal customer profile and a list of famous brands leave most of a market untouched, how to map audiences of people who share a situation, turn them into searches a contact database can run, and size the market honestly. With examples from SLSBMB AI's published playbooks.

Every guide describes how SLSBMB AI works. If you run outbound yourself, the same rules apply to your own setup.
