Cold email that reads like
someone did the homework.
Acqro researches every company on your list — funding, hiring, launches, leadership moves — then writes each email from what it actually found. No templates. No spin syntax. No merge-field theatre.
Onboarding in batches. No credit card to join.
Sarah — saw the regional office announcement, and that you're actively hiring three project architects to staff it.
Opening new offices often means design standards can drift before the team is fully onboarded. That's the gap we close for firms scaling their urban design portfolios.
Worth a brief call before the new team ramps up?
What is Acqro?
Acqro is AI cold email software for B2B teams that researches each prospect's company before writing to them. It gathers public signals — funding rounds, hiring activity, product launches, leadership changes, published positioning — and drafts outreach grounded in those specific findings, showing the sources behind every claim. Verification, authenticated sending domains, warmup, throttling, and a unified reply inbox are built in.
Personalization stopped working because it stopped being personal
Merge fields and spin syntax were a workaround for a research problem. Buyers learned the pattern years ago.
"Hi {FirstName}, I loved your work at {Company}"
Recipients recognize a variable when they see one. A first name in the subject line is not personalization — it is proof that a script sent the message.
Volume compensates for irrelevance
When reply rates fall, the reflex is to send more. That raises complaint rates, burns domains, and trains filters on your fingerprint — accelerating the decline it was meant to fix.
Real research doesn't scale by hand
A rep who genuinely researches an account needs 15–20 minutes per prospect. That caps a full-time SDR at roughly 20 accounts a day, which is why almost nobody actually does it.
Research first, then write, then send carefully
The same sequence a strong SDR follows — executed on every account instead of the first twenty.
Build and verify the list
Define the target profile by industry, size, geography, and role. Acqro assembles matching contacts and verifies every address before anything is queued — heuristics, DNS and MX checks, catch-all detection, and role-account filtering.
Research each company
Acqro reads each target's public footprint — announcements, careers pages, press coverage, product changes, leadership updates — and extracts the signals that give you a legitimate reason to reach out. Every finding keeps its source link.
Draft from the evidence
Each email is written against that specific company's findings and your positioning. You see the rationale and sources beside every draft, edit anything you want, and approve in bulk or one at a time.
Send on protected infrastructure
Sending runs through authenticated secondary domains with SPF, DKIM and DMARC, gradual warmup, per-mailbox daily caps, and randomized gaps. Your primary domain stays out of the blast radius.
Work the replies
Responses land in one inbox, classified by intent — positive, question, referral, objection, auto-reply, unsubscribe. Follow-ups stop automatically the moment a human replies.
One system instead of five subscriptions
Prospecting, verification, research, drafting, sending, and reply management in a single tool.
Company intelligence
Automated research on every account with cited sources and a confidence indicator. Nothing is asserted without something behind it.
Verification built in
Addresses validated before send, with catch-all and role-account detection. List health surfaces as a single status, not a wall of counters.
Deliverability guardrails
SPF, DKIM and DMARC checks per sending identity, automated warmup schedules, per-mailbox throttling, and bounce thresholds that flag problems early.
Sequences that stop
Multi-step follow-ups with reply detection, so a prospect who answers never receives step three. Timing and send windows respect the recipient's business hours.
Unified reply inbox
Every response across every sending mailbox in one thread view, classified by intent so positive replies never get buried under auto-responders.
Compliance fields
Physical address, accurate sender identity, one-click opt-out, and permanent suppression handling — the CAN-SPAM requirements enforced at the platform level.

The numbers that decide whether outbound works
Acqro monitors these against known-good ranges and flags drift before it costs you a domain.
- Hard bounce ceiling
- 2% max
- Daily send per mailbox
- 30–50emails
- Domain warmup period
- 3–4weeks
- Spam complaint ceiling
- 0.1% max
Why campaigns usually fail
- The list was never verified, so bounces spiked in the first week and the domain never recovered.
- Volume ramped faster than the warmup schedule allowed.
- Outbound ran from the primary corporate domain, putting transactional email at risk.
- The offer was relevant to 5% of the list, and the other 95% marked it as spam.
- Performance was judged after 200 sends — far too few to distinguish signal from noise.

The questions buyers actually ask before committing to an outbound program.
How is Acqro different from Instantly, Smartlead, or Apollo?
Most sequencers are delivery infrastructure: you supply the copy and the list, they handle rotation and scheduling. Personalization stops at merge fields and spin syntax. Acqro adds the research layer in front of that — it decides what to say about each company based on evidence it gathered, and shows you the sources behind each draft. You still get the sending infrastructure; the message itself is generated from context rather than assembled from a template.
Does AI-written cold email actually land in the inbox?
Deliverability is determined by authentication, sending reputation, list quality, and engagement — not by whether a human or a model wrote the text. Acqro enforces the technical side: SPF, DKIM and DMARC on separate sending domains, gradual warmup, per-mailbox daily caps, and pre-send verification.
Because every message is written from company-specific research, the content also avoids the repetitive fingerprints filters learn to recognize across identical bulk sends.
What is a realistic reply rate for B2B cold email?
Published industry benchmarks put average B2B cold email reply rates in the 1–3% range for generic, templated campaigns. Well-targeted campaigns with genuine personalization and a narrow list typically perform several times better.
Reply rate is driven far more by list precision and offer relevance than by copywriting technique — which is why Acqro invests in research and verification before drafting anything.
Is cold email legal in the United States?
Yes. CAN-SPAM permits unsolicited commercial email to business contacts in the US, provided the message identifies the sender accurately, includes a valid physical postal address, uses non-deceptive subject lines and headers, offers a clear opt-out, and honors opt-out requests promptly.
Contacting recipients in the EU and UK brings GDPR and PECR into scope, where legitimate interest must be documented. Acqro includes the compliance fields and suppression handling these rules require — though it is not a substitute for legal advice.
Do I need separate domains to send cold email?
Yes, for any meaningful volume. Sending outbound from your primary corporate domain puts transactional and internal email at risk if reputation degrades. Standard practice is to register lookalike secondary domains, authenticate each with SPF, DKIM and DMARC, warm them gradually over several weeks, and cap daily volume per mailbox. Acqro manages this setup and enforces the caps automatically.
How many emails per day can I safely send from one mailbox?
A warmed mailbox on a healthy domain generally sustains 30–50 cold emails per day. New mailboxes should start far lower — roughly 5–10 per day — and increase gradually across a three to four week warmup.
Scale comes from adding mailboxes and domains, not from raising the per-mailbox ceiling.
What bounce rate should trigger concern?
Keep hard bounces under 2%. Between 2% and 5% indicates list quality problems worth fixing before scaling. Above 5% is actively damaging to sending reputation and usually means the list was never verified or has gone stale. Acqro flags bounce rates against these thresholds directly in campaign analytics rather than reporting them as neutral numbers.
How long does it take to see results?
Plan on three to four weeks of domain warmup before meaningful volume, then two to four weeks of sending to gather statistically useful data. First replies often arrive within days of launch, but a reliable read on campaign performance usually takes six to eight weeks from setup.
Who is Acqro built for?
B2B teams selling considered purchases where the buyer list is finite and each account is worth researching — agencies, professional services firms, SaaS companies, managed service providers, staffing and recruiting firms, and consultancies.
It is a poor fit for high-volume, low-value transactional selling where personalization does not change the economics.
What does Acqro cost?
Credit-based plans start at $99 per month, with managed outreach programs available up to $1,999 per month. Credits are consumed by company research and draft generation, so cost scales with how much outreach you actually run. Full breakdown on the pricing page.
