cold-email

what it does

Write and run B2B cold outbound that gets replies, from cold emails and follow-ups to sending setup, LinkedIn, multichannel cadences, and reply handling. Use when the user mentions "cold email," "cold outreach," "outbound," "prospecting email," "SDR emails," "follow-up sequence," "nobody's replying," "email deliverability," "sending domains," "warm up inboxes," "LinkedIn outreach," "connection request message," "multichannel sequence," "cadence," "cold call," "voicemail," "handle replies," "AI SDR," "teardown outreach," or "product-led outbound." Send from secondary domains, verify lists first, turn off open tracking, and stop every channel when a prospect replies. Copy avoids AI tells like 'it's not X, it's Y' reveals. For building the list and account research, see prospecting. For lifecycle email, see emails. For call scripts and sales collateral, see sales-enablement.

“Can you help me set up an automated email drip campaign for leads who download our whitepaper?”

with the skill
Happy to. Since these leads opted in by downloading, this is a nurture sequence rather than cold outreach, so some cold-email rules relax (links, click tracking, and a slightly longer length are fine) while others stay (plain, human tone, one ask per email, value in every touch). ## Suggested sequence (5 emails over about 3 weeks) | Email | Timing | Purpose | CTA | |---|---|---|---| | 1. Delivery | Immediately | Deliver the whitepaper, name the one idea worth reading first | Download link, plus "reply if you want my take on X" | | 2. Key insight | Day 2-3 | Expand the most useful finding with a concrete example | Read the relevant section or a short post | | 3. Proof | Day 6-7 | Short case study of a similar company applying the idea | Read the case study | | 4. Next resource | Day 11-13 | A checklist, calculator, template, or webinar that moves them toward action | Use the resource | | 5. Conversation | Day 18-21 | Soft offer of a call, framed around their situation | "Worth a 20-minute look?" | After email 5, move them into your regular newsletter or a slower nurture track. ## Rules that make it work - **Exit conditions:** Stop the sequence when someone books a demo, replies, becomes an opportunity, or is already a customer. - **Sales alerts:** Notify a human on replies, repeat clicks, or pricing-page visits. Don't wait for email 5. - **Segment if you can:** Role or industry from the form lets you swap in the right example or case study. - **Sender:** Use a real person's name and address, not "Marketing Team." Replies are your best signal.

- **Compliance:** Include a working unsubscribe link and your postal address. If you have EU/UK leads, make sure the download form has a clear marketing opt-in, since downloading alone usually isn't consent for ongoing marketing. - **Measure:** Replies, click rate on the CTA, whitepaper-to-meeting rate, and unsubscribes (keep under about 0.5% per send). ## Sample copy (placeholders in brackets) **Email 1, subject: your copy of [whitepaper short title]** > Hi [first name], > > Here's the whitepaper: [link] > > If you only have ten minutes, start on page [X]. That's where we cover [the most surprising or useful finding], which most [role] teams underestimate. > > If you read it and want a second opinion on how it applies to [their likely situation], just reply. I read everything that comes in. > > [Name] > [Company, postal address] | [unsubscribe link] **Email 2, subject: the [topic] number most teams miss** > Hi [first name], > > One finding from the whitepaper gets the most questions: [key insight in one sentence]. > > A quick example: [one-paragraph, concrete illustration with a number or outcome]. > > If that matches what you're seeing at [their company type], I'd be curious how you're handling it today. A one-line reply is plenty. > > [Name] I can write emails 3 to 5 the same way once I know a bit more. ## What I need to tailor this 1. What's the whitepaper about, and who downloads it (roles, company size)? 2. What's the goal: demos, trials, or just staying top of mind? 3. What proof do you have (a case study, a customer result, a stat)? 4. Which tool are you using (HubSpot, Marketo, ActiveCampaign, Mailchimp, etc.)? I can give you the specific workflow setup, including triggers and exit rules. 5. Who follows up on high-intent leads, and how fast? If you'd rather I just run with assumptions, tell me the whitepaper topic and I'll draft the full five emails.

# Whitepaper Drip Campaign Setup ## 1. Foundation (before you build) **Define the goal.** Pick one primary outcome: demo request, free trial, sales call, or webinar signup. Every email should point toward it. **Tools you'll need:** - A marketing automation platform (HubSpot, ActiveCampaign, Mailchimp, Klaviyo, Marketo, Customer.io, etc.) - A landing page and form that feeds into it - CRM integration, if sales will follow up **Capture useful data on the form:** name, email, company, and role. Add one qualifying field (company size or biggest challenge) if it won't hurt conversion much. ## 2. Suggested 5-Email Sequence | # | Timing | Purpose | Content | |---|--------|---------|---------| | 1 | Immediately | Deliver | Download link, a 2-3 line summary of key takeaways, and a soft "reply with questions" | | 2 | Day 2-3 | Add value | Highlight one key insight from the whitepaper with a short story or stat, and link to a related blog post | | 3 | Day 5-7 | Build trust | Case study or customer result tied to the whitepaper's topic |
Show the rest (67 more lines)
| 4 | Day 10-12 | Educate/engage | Invite to a webinar, checklist, calculator, or other related resource | | 5 | Day 14-16 | Convert | Direct CTA: demo, consultation, or trial, with a clear benefit | **Optional email 6 (Day 21+):** A "breakup" email ("Should I close your file?") often gets strong replies. Then move non-responders to your regular newsletter. ## 3. Sample Copy **Email 1: Delivery** > **Subject:** Your copy of [Whitepaper Title] > > Hi {{first_name}}, > > Thanks for downloading *[Title]*. [Download it here]. > > If you're short on time, the three big takeaways are: > - [Insight 1] > - [Insight 2] > - [Insight 3] > > If any of it raises questions about your situation, just reply. I read every response. > > — [Name] **Email 5: Conversion** > **Subject:** Want to see how this applies to {{company}}? > > Hi {{first_name}}, > > Teams that put the ideas from [Title] into practice typically see [specific result]. If you'd like to see what that could look like for {{company}}, we offer a free 20-minute walkthrough. > > [Book a time] > > No pressure. Either way, I hope the paper was useful. ## 4. Automation Rules - **Exit conditions:** Remove contacts from the sequence if they book a demo, become a customer, or reply. - **Behavior branching:** If someone clicks the case study but doesn't convert, send a more direct follow-up. If they never open emails 1-3, resend with a new subject line. - **Lead scoring:** Add points for opens, clicks, and pricing page visits. Alert sales at a threshold you set. - **Suppression:** Exclude existing customers and people already in other active sequences. ## 5. Best Practices - **Send from a real person's name**, not "noreply@". - **Keep emails short:** 100-150 words, one CTA each. - **Write subject lines under 50 characters**, and A/B test them. - **Authenticate your domain** (SPF, DKIM, DMARC) to avoid spam folders. - **Stay compliant:** include an unsubscribe link and your physical address, and make sure consent language is on the form (GDPR/CAN-SPAM/CASL as applicable). ## 6. Metrics to Track | Metric | Rough benchmark | |---|---| | Open rate | 30-45% (B2B) | | Click rate | 3-7% | | Conversion to demo/trial | 2-5% of sequence | | Unsubscribe rate | <0.5% per email | Review after 30-60 days, then tweak the lowest-performing email first. ## To tailor this, I'd need to know: 1. Is this B2B or B2C, and what's your product or service? 2. Which email platform are you using? 3. What's the end goal (demo, trial, purchase)? 4. Do you have other content (case studies, webinars) to use in the sequence? If you share the whitepaper topic and your platform, I can write the full email copy and give platform-specific setup steps.
