TL;DR — 5 things to know before reading
The first mistake in cold email campaign setup is treating industry as the only targeting filter and stopping there. An industry filter applied without job title and seniority filters produces a list that includes everyone from the CEO to the intern in that vertical — a list where no single message can be relevant to the full range of recipients. Industry targeting is the starting point, not the complete targeting strategy.
The second mistake is assuming that some industries "work" for cold email and others do not. Every B2B industry has decision-makers who receive cold email, evaluate vendors, and reply to messages that reach them with a relevant, well-timed offer. The question is not which industry responds — it is whether your ICP definition is specific enough within that industry to enable personalised outreach. Quarvio covers 150+ industries with full filter combinations; Instantly runs the campaigns on Inframail infrastructure; Aimfox runs LinkedIn outreach in parallel for multichannel coverage in any vertical.
Quarvio allows industry selection as one component of a multi-filter order. A complete industry-targeted order typically combines:
| Filter | Example values |
|---|---|
| Industry | Information technology & services, financial services |
| Job title | VP of Sales, Head of Revenue |
| Seniority | Director, Vice President, Executive (C-Suite) |
| Company size | 51–200, 201–500 |
| Geography | United States, United Kingdom |
All filters apply simultaneously. The resulting contact list contains only records that match every filter you set — not an industry-wide export that you then have to filter yourself.
The industry list Quarvio supports includes 150+ standardised industry classifications across all major B2B verticals. You can select multiple industries in a single order (for example: both "legal services" and "accounting" for a financial software offer).
One of the largest pools of B2B cold email contacts. Software companies, IT services firms, managed service providers, and SaaS companies are all concentrated in this vertical. Decision-maker titles include: CTO, VP of Engineering, Head of IT, Director of Technology, VP of Product.
What works in this vertical: technology buyers are typically well-informed about vendor categories. Messages that reference a specific pain point (onboarding friction, security compliance, integration overhead) outperform generic capability statements. Company size matters significantly — a 15-person SaaS startup and a 5,000-person IT services firm have completely different buying processes.
Filter recommendation: combine information technology & services or computer software with company size (e.g. 51–500 for mid-market, or 11–50 for SMB) and seniority (Director and above for strategic decisions).
Includes banks, insurance companies, investment firms, financial advisory firms, and fintech companies. Decision-makers include: CFO, VP of Finance, Chief Compliance Officer, Head of Risk, Director of Operations.
What works in this vertical: financial buyers respond to compliance-relevant and efficiency-relevant messaging. Regulatory framing, audit trail capabilities, and cost-per-outcome comparisons outperform feature-focused messages. Personalisation by company type (bank vs. insurance vs. fintech) is more effective than generic "financial services" positioning.
Filter recommendation: combine banking, financial services, insurance, or investment management with senior seniority filters (C-Suite, VP, Director) and geography (US, UK, or India as the three largest English-language financial markets).
Law firms, consulting companies, accounting firms, management consultancies, and staffing agencies. Decision-makers include: Managing Partner, COO, Director of Operations, Head of Business Development.
What works in this vertical: professional services buyers respond to peer proof — outcomes achieved for firms like theirs. Compliance and efficiency messaging performs well. Partnership-framing ("working with firms like yours") outperforms vendor-framing in this vertical.
Filter recommendation: combine management consulting, law practice, legal services, or accounting with company size (typically 11–500 employees for the most reachable decision-makers) and seniority (Partner, Director, C-Suite).
Includes hospitals, medical practices, health systems, medical device companies, and health tech. Decision-makers include: CMO, VP of Operations, Director of Clinical Operations, Practice Manager, CIO.
What works in this vertical: healthcare buyers move slowly and have strict compliance requirements. Messages framed around patient outcomes, operational efficiency, or regulatory compliance outperform general sales messaging. Lead times are longer than in tech or professional services.
Filter recommendation: combine hospital & healthcare, medical practice, or medical devices with seniority (Director and above) and company size appropriate to your offer (small practices vs. health systems have radically different buying structures).
Includes industrial manufacturers, consumer goods producers, food & beverage companies, and automotive suppliers. Decision-makers include: VP of Operations, Head of Supply Chain, Director of Procurement, Plant Manager, COO.
What works in this vertical: manufacturing buyers are operationally focused. Efficiency, downtime reduction, and supply chain reliability are the primary themes that drive response. Technical specificity outperforms abstract value propositions in this vertical.
Filter recommendation: combine manufacturing, industrial automation, or machinery with operational function filters (Operations, Supply Chain, Engineering) and company size (typically 51+ employees; larger for supply chain tools).

Every Quarvio list ships verified. If deliverability falls below 90% on any delivered list, report it within 7 days with your bounce export and credits return for the shortfall above the 10% allowance. Per Google's email sender guidelines, maintaining bounce rates below 2% is critical to inbox placement — the guarantee ensures industry-targeted lists meet this standard.
Per Woodpecker's 2025 cold email benchmark study, the average cold email reply rate is 8.5% and the top quartile achieves 15–20%. Industry targeting improves results when combined with title and seniority precision because it enables vertical-specific personalisation. The campaigns consistently outperforming average do one thing: they sound like they were written for the specific person receiving them, referencing their industry context rather than speaking generically about "businesses like yours."
Per Instantly's cold email benchmark report, elite senders achieve above 10% reply rates. The primary driver is not volume or sequence design — it is the match between the contact's role, industry, and company type and the message they receive.
"We started running separate campaign variations per industry vertical last year and the reply rate difference was immediate. The same core offer, reframed for legal vs. for finance vs. for healthcare, produced different reply rates per vertical. The legal version has been our best performing one at 16% reply rate. You cannot achieve that by sending one message to a mixed-industry list."

"Ordering by industry from a verified provider and segmenting into vertical-specific campaigns was the operational change that scaled our agency from 15 clients to 40+ in six months. We now order industry-specific lists and run vertical-specific sequences. The reporting to clients is cleaner, the performance is better, and the cost per usable contact is lower than when we were using subscription databases."

Which industry has the highest reply rate for cold email?
There is no single answer — reply rate depends on the match between the offer and the recipient's role and pain point, not on which industry is "better" for cold email. Information technology, professional services, and financial services tend to have high concentrations of English-speaking decision-makers reachable by email, which makes list-building easier. But a well-targeted message to a manufacturing decision-maker about a relevant operational problem will outperform a generic message to a tech buyer every time. Target the industry where your ICP actually sits, not the industry with the largest contact pool.
Can I order B2B contacts from multiple industries in a single Quarvio order?
Yes. Quarvio allows multi-industry selection in a single filter set. You can select, for example, legal services and management consulting together in one order. If you want industry-specific segmentation in the delivered CSV (to run separate campaigns per vertical), you can place separate orders per industry and receive separate files.
How many contacts should I order for an industry-targeted campaign?
The standard starting size is 500–2,000 contacts per campaign segment (one industry, one job title cluster, one geography). This range produces enough data to evaluate reply rate meaningfully while keeping the initial investment manageable. If the test segment performs above 8% reply rate, scale with a larger order. Most Quarvio orders in the 5,000–10,000 range cover 2–4 campaign segments at this starting size.
Does Quarvio cover international industry contacts or only US?
Quarvio covers contacts globally. The most common geographies ordered are United States, United Kingdom, and India, but all countries are available in the geography filter. Industry classifications use standardised global categories that apply consistently across geographies. You can order, for example, financial services contacts in Germany or manufacturing contacts in Japan using the same filter interface.
How do I personalise cold email to industry-specific contacts at scale?
The key is matching your message framing to the operational context of the industry. For financial services: reference compliance, risk, or audit. For technology: reference integration, scalability, or onboarding time. For professional services: reference billable hour efficiency or client delivery. The job title and industry from each Quarvio contact record give you two personalisation variables in your opening line without any additional research. Import the CSV into Instantly with job title and company as custom variables and use them in the opening line to differentiate each message.
