how i 2x'd cold email replies with ai icebreakers

most ai icebreakers suck. they’re generic, robotic, and get ignored.

but if you do it right, ai personalization can 2x your cold email replies —turning 1 booked call/day into 2 and even more… without sending more emails.

here’s how to do it 👇

why it works

decision-makers get 8–20 cold emails/day. yours needs to stand out.
personalization is an amplifier: 3% reply rate → 6% reply rate.
but ai should only write your icebreaker, not the whole email.

step-by-step

scrape lead data from linkedin using apify or EXA AI
send that data to ai with a good prompt (rules, examples, clear tone)
ai writes 1–2 sentences (the icebreaker)
you write the rest of the email yourself
send & watch replies go up

prompt tips

tell ai who it is (“you’re an sdr writing warm, specific compliments”) (using the system prompt)
feed it rich inputs (job title, niche, achievements, signals)
set rules (no full names, warm tone, under 2 sentences)
use placeholders for specific signals + metrics you want referenced

here's the prompt if you wanna copy it :

We just scraped a linkedin profile. Your task is to take their summaries and turn them into catchy, personalized openers for a cold email campaign to imply that the rest of the campaign is personalized.

You'll return your icebreakers in the following JSON format:

{

"icebreaker": "Cool move building out/That shift into {thing} stood out/Smart play using {superSpecificThing}, especially the part about {specificSignal}.\n\nNoticed {anotherThing} came up too, so figured I’d reach out with something that might be helpful."

}

Rules:

- Keep the tone warm, simple, and friendly, like you're talking to someone at a coffee shop. Think 3rd or 5th grade reading level.

- No full names in the icebreaker. That reads too robotic.

- Make sure to use the above format when constructing your icebreakers. We wrote it this way on purpose.

- Mix up the first sentence starter using warm, friendly phrases pick what fits best based on what you're referencing.

- Use the cleaned company name wherever possible (say, "XYZ" instead of "XYZ Agency"). More examples: "Love AMS" instead of "Love AMS Professional Services", "Love Mayo" instead of "Love Mayo Inc.", etc.

- For your variables, focus on small, non-obvious things to paraphrase. The idea is to make people think we *really* dove deep into their linkedin, so don't use something obvious. Do not say cookie-cutter stuff like "Love your website!" or "Love your take on marketing!". Do reference things like career transitions, niche terminology, under-the-radar content, or unique side projects.

- Embrace simplicity over cleverness. If two wordings mean the same thing, use the cleaner one. Sound smart by saying less.

- Do not pretend to share interests or experiences you don’t actually have. Avoid implying deep personal alignment or expertise unless it's true. Use surface-level relatability (e.g., “doing lean product work myself” only if you actually are). Don’t fake mutual interest in niche fields just to create rapport. Keep it ethical, clear, and halal.

-When referencing their background, subtly relate your observation to automation, ops, efficiency, or leverage—especially if they’re in marketing, product, or tech. Look for under-the-radar clues that they value systems: mentions of scale, workflow, process improvements, operational roles, niche tech, or startup velocity.

- Avoid Mild vagueness in phrases like "niche frameworks", "tailored outsourcing", or "tech stacks", be more concrete. E.g., instead of “niche frameworks” say “Laravel/Odoo buildouts” or “custom IDX integrations” if you know the stack.

- Be more daring with your second line. For example, instead of: “Looks like streamlining ops is top of mind, so thought I’d reach out..." Try: “That’s not something most agencies solve cleanly—figured this might help.” Or:

“Few teams get that right at scale—figured I’d share something tight.”

- Ground your icebreakers strictly in observable truths. Don’t attribute product/ops work where it doesn’t clearly exist.

- Rule of thumb for icebreakers : If you can’t name something that would make a peer go “ah, they get it, they did their homework”, you haven’t gone deep enough.

- Don't use any em dashes.

- Don't use any TM or trademark logo in the icebreaker.
