Skyp's AI writes unique emails per contact with managed deliverability.

Not templates. Not spray and pray. app.skyp.ai/campaigns/preview ## Cold outbound to people who do not know you yet For B2B sales teams selling high-value products and services Cold email is a sales and marketing technique where you send unsolicited emails to prospective customers who have not previously interacted with your company. Unlike spam, effective cold email is targeted, relevant, and personal: the recipient is a plausible buyer, and the message is written for them specifically. Crucially, cold email is a B2B discipline: you are reaching business buyers, not consumers. Cold email works differently at different price points. For lower-cost products, companies focus on volume. Some send a million or more emails per month using tools like [Instantly](/alternatives/instantly) or [Smartlead](/alternatives/smartlead). You can [compare popular cold email tools here](/compare). When the average contract value is $50,000 or more, high volume is counterproductive. If you only have 10,000 possible customers, sending mass campaigns means reaching them all in a day. This is called burning through your TAM. Low-quality emails hurt your reputation with the exact people you most need to impress. Certain tools are built for this high-value context. You can automate the parts that do not require human judgment: finding contacts, provisioning sending infrastructure, writing thoughtful personalized emails, following up, and tracking results, without removing the human from the loop on things that matter, and without spray-and-pray tactics that ruin your deliverability and reputation. ## When cold email works best ### High-ACV B2B sales Cold email moves buyers through awareness and consideration. Even if they do not reply immediately, a well-written email builds familiarity that makes later outreach more effective. ### Drive awareness and website visits Cold email gets your target customers to visit your website, read your content, and learn what you do. Most buyers who eventually purchase were touched by outreach long before they were ready to buy. ### Fill webinars, events, and demos A well-timed cold email to the right person gets them on a webinar call or demo if they are in-market right now. For everyone else, it keeps your company top of mind for when they are ready. ### Nurture your TAM over time Cold email is not just about immediate replies. A sequence of relevant, well-timed messages keeps your company visible to buyers who are not ready yet but will be. That familiarity converts when they enter the market. ## Why most cold email does not work Most cold email fails for three predictable reasons. None of them are about volume. - **Templates that read like templates**: Spam filters and prospects both recognize merge-field personalization. One custom line in a generic email is not personalization. Recipients delete it before the second paragraph. - **Infrastructure that kills deliverability**: Sending from your primary domain, skipping warmup, or misconfiguring SPF and DKIM damages your sender reputation. Most teams do not know their emails are not being delivered until it is too late. - **Metrics you cannot trust**: Security scanners, Apple MPP, and link preview bots all register as opens and clicks. Most platforms report inflated numbers. You are making decisions based on phantom engagement. ## What features to expect in a cold email tool Four things have to work together. If any one of them breaks, the whole motion breaks. ### 01. Writing #### Write a different email for every contact The only cold email that gets a reply is one that feels like it was written for that specific person. Skyp's AI researches each contact before writing: their role, their company's recent news, their tech stack, their open positions. The result is an email that reflects what was found, not what was filled into a template. - Unique email per contact, written from scratch - AI researches each contact before writing - Tone, length, and CTA configurable per campaign - Compliance guardrails for regulated industries ### 02. Deliverability #### Get your emails into the inbox Deliverability is an infrastructure problem, not a content problem. Skyp provisions and manages everything before your first campaign: dedicated sending domains, professional Google inboxes, warmup schedules, SPF, DKIM, DMARC, and custom tracking domains. The platform maintains a 97.2% delivery rate across all campaigns. - Done-for-you domain registration and DNS setup - Professional Google inboxes provisioned per rep - Inbox warmup and health monitoring - 97.2% platform delivery rate ## Campaign Performance ### Last 30 days - **Delivery Rate**: 97.2% (Industry avg: 85–90%) - **Open Rate**: 37.9% (Industry avg: 15–20%) - **Reply Rate**: 5.2% (Industry avg: 1–3%) ### Recent Campaigns - Fintech SaaS: Q2 Reactivation - 847 contacts - 99.1% delivered - 41% open rate - Series B Founders: Cold Outreach - 412 contacts - 98.4% delivered - 38% open rate - RevOps Leaders: Product Launch - 1,203 contacts - 97.8% delivered - 35% open rate ### 03. Sequences #### Follow up without thinking about it Nobody replies to the first email. Multi-step sequences are the standard, but managing them manually across dozens of contacts and campaigns is a full-time job. Skyp runs sequences automatically and stops them the moment someone replies or books a meeting. No awkward follow-ups to people who already responded. - Multi-step sequences, automatically managed - Auto-stop on reply or meeting booked - Sending schedule controls per campaign - Evergreen campaigns that run indefinitely ### 04. Analytics #### Know what is actually working Cold email analytics are notoriously unreliable. Security scanners open your emails. Apple Mail Privacy Protection prefetches your tracking pixels. Skyp runs every engagement event through a 25-stage bot-filtering pipeline before it shows up in your dashboard. When you see a 28% open rate, it means 28% of real humans opened your email. - Bot-filtered open, click, and reply rates - Engagement classification: human vs scanner - Meeting booked attribution - AI weekly campaign commentary ## Common questions about cold email ### What is a cold email sequence? A sequence is a series of emails sent to the same contact over days or weeks — an initial message followed by follow-ups if there is no reply. Most buyers need multiple touches before they respond, so a sequence dramatically outperforms a single email. The best sequences are not just the same message resent. Each step should add something new or take a different angle. ### What is a cold email template, and why should you avoid them? A template is a pre-written email with placeholder fields — things like {first_name} or {company}. Templates are the standard approach in most cold email tools because they are easy to write once and send many times. The problem is that recipients can tell immediately. ### What is a good cold email response rate? For high-ACV B2B cold email, a 2-5% positive reply rate is strong. A 1% rate is typical for most campaigns. Open rates of 30-50% are achievable with good deliverability and a relevant subject line. ### What is the difference between cold email and spam? Spam is untargeted, irrelevant, and often fraudulent. Cold email is targeted, relevant, and from a real business reaching a plausible buyer. The practical difference is specificity: a spam email could be sent to anyone; a cold email was written with a specific person in mind. ### How many cold emails should I send per day? For high-ACV B2B outreach, 20-50 emails per inbox per day is a safe range after proper warmup. ### How do I improve cold email deliverability? The four most important factors: (1) send from a dedicated domain, not your primary business domain, with SPF, DKIM, and DMARC configured correctly; (2) warm up your inboxes; (3) keep your list clean; (4) write emails that are structurally unique and relevant to each recipient. ### Is cold email legal? Yes, in most jurisdictions, cold email to B2B buyers is legal when you follow applicable rules. ## What our customers say > "Setting up Skyp was easy. I got a reply in the first day–and was able to send 188 follow ups I would never have gotten to without it." **Ivan Smilianic** Partner, Innovation Properties Group > "Skyp delivered.

A cold email tool is software that helps sales teams send personalized outreach to prospects who haven't contacted them before. Unlike marketing email platforms designed for newsletters and existing subscribers, cold email tools are built for one-to-one prospecting. ## What makes a cold email tool effective? Most cold email tools send at scale. The best cold email tools send at scale and get replies. Here's what separates them: ### Unique emails per contact, not templates The best cold email software writes a distinct email for each recipient using their actual data—company news, job title, tech stack, or intent signals—rather than plugging a name and company into a single template. ### Deliverability management built in Cold email deliverability requires properly configured sending domains, inbox warming, and volume management. ### Multi-step sequence support Cold outreach rarely converts on the first touch. Effective cold email software runs multi-step sequences—initial email, follow-ups, and re-engagement—automatically. ### CRM and list integration A cold email tool that requires you to re-enter contacts manually creates duplicate work. ### Reply tracking and campaign analytics You need to know which campaigns are working and which aren't. A solid cold email tool tracks opens, replies, and meeting bookings at both the campaign and individual contact level.
