Professional templates for authority sites. Casual templates for small publishers. Subject line variants for A/B testing. Built on data from 34M+ analyzed emails.
The average cold outreach email gets a 3.4% reply rate (Instantly, 2026 benchmark across 1B+ emails sent). That means for every 100 emails you send, roughly 3 people respond. Most of those are "no thanks."
The top 10% of campaigns hit 15% or higher. The difference isn't volume or clever tricks. It's specificity and tone matching. An email that works on a DR 60 editor will get deleted by a solo blogger, and vice versa.
That's why this collection has three tone categories. Professional templates for authority sites. Casual templates that read like DMs for small publishers. Direct templates that strip everything to the bare minimum. Each includes subject line variants for A/B testing and the reasoning behind every structural choice. Built on the research from our Cold Email Playbook.
Structured paragraphs. Full sentences. "Hi there" greeting. Clear sign-off.
"I'm a regular reader of your site and wanted to reach out about..."
Lowercase subjects. No formal greeting. Reads like a text or DM. Short sentences.
"hey, just read your piece on... quick ask: would you be open to swapping that link?"
Under 30 words. No pleasantries. One sentence, one question. Get in, get out.
"any chance you'd swap the [anchor] link for [site]? same topic, just more current."
Mention the article title and the exact anchor text they used. This proves you actually visited their site and aren't mass-blasting.
Hunter.io found personalized first lines increase reply rates by 2.3x.
Lavender's analysis of 24M+ emails showed that messages under 100 words get 51% reply rates. Every template in this set is under 65 words.
Lavender, 2024. 24M+ email dataset.
Don't ask them to check your site AND reply AND let you know their thoughts. Pick one action. "Would you be open to taking a look?" is enough.
Woodpecker found single-CTA emails get 28% higher response rates.
A DR 70 editor expects polished outreach. A DR 20 solo blogger responds to casual, real-sounding emails. Pick the tone that matches the recipient, not the one you're most comfortable writing.
Backlinko analysis of 12M outreach emails.
The 3-7-7 cadence (Day 3, Day 10, Day 17) captures 93% of all replies that will ever come. Going beyond 4 follow-ups has diminishing returns and risks spam complaints.
Woodpecker, 20M email study.
One genuine sentence about their content ("I loved the section on X") is the single highest-leverage personalization. It proves you read the page, not just the title.
Instantly, 2026. Campaigns with per-prospect personalization: 15%+ reply rate vs 3.4% average.
The single biggest upgrade to any template is one genuine sentence about the recipient's content. Not a generic compliment. Something specific enough that they know you actually read the page.
Hunter.io's analysis of 34M campaigns found that personalized first lines increase reply rates by 2.3x. Instantly's 2026 data shows campaigns with per-prospect personalization hit 15%+ reply rates versus the 3.4% average. The {{content_hook}} variable is where that happens.
"I loved the breakdown of arcade opening hours by region. I've been trying to find that data for months."
"Great article! Really enjoyed it."
"Your comparison of Pitchbox vs Respona pricing was the most honest one I've seen."
"I found your content very informative and well-written."
Template #12 (The Compliment First) uses this variable directly. But you can add it to any template by inserting one sentence after the opening line. The key: it has to be specific enough that it could only apply to that one article, not to any article in the niche.
Every template uses dynamic variables that get replaced with real data for each prospect. HeyLinks fills these automatically from the research data it collects.
Match your outreach scenario to the right template. The decision depends on what data you have about the prospect, the page context, and the recipient's site size.
10 structured templates for mid-to-high authority sites. These use proper greetings, full sentences, and clear sign-offs. Best for DR 30+ sites where the recipient is an editor or content manager.
6 templates that read like messages from a real person, not a link building campaign. These are designed for solo bloggers, niche site owners, and small publishers (typically DR under 30) who will immediately delete anything that sounds like a template. Lowercase subjects, no formal greetings, conversational tone throughout.
The 3-7-7 cadence: follow up on Day 3, Day 10, and Day 17 after your initial email. The fourth email is a breakup that triggers loss aversion. This sequence captures 93% of all replies that will ever come.
The biggest variable is usually tone, not structure. Try The Simple Ask (#4, professional) against The Twitter DM (#11, casual) on the same prospects. See which tone your niche responds to before optimizing word choice.
Each template includes 2-3 alternative subject lines. Swap only the subject between variants and keep the body identical. This isolates the open rate variable. Short subjects (1-5 words) outperform long ones by 16%.
Anything under 50 is noise. At 50+ sends per template, you'll have enough data to see statistically meaningful differences in reply rates.
Open tracking is increasingly unreliable (Apple Mail Privacy Protection, corporate email proxies). Reply rate is the ground truth metric for outreach.
Match your tone to your audience. Professional for authority sites, casual for small bloggers. This matters more than any other optimization.
Every template is under 65 words. Shorter emails consistently outperform longer ones across every study we analyzed.
The {{content_hook}} is the highest-leverage personalization variable. One genuine sentence about their content is worth more than a perfectly structured email.
The follow-up sequence is where most replies come from. 44% of senders give up after one email. Don't be one of them.
A/B test tone first, details second. Once you know whether your niche responds to professional or casual, optimize from there.
