How accurate data supercharges your cold outreach

You can follow the best cold email template, write the punchiest subject line, and personalise the perfect message. But if it lands in the wrong inbox or no inbox at all – your effort goes to waste.

That’s where accurate data comes in.

In 2025, outreach success isn’t just about the message. It’s about who you’re reaching, when you reach them, and how clean your list is. If you’ve already read our cold email templates guide, this post is your next step: refining the inputs behind your outreach engine.

Why data accuracy is critical in 2025 

Cold outreach used to be a volume game. Now it’s about timing, targeting, and trust. Quality over quantity. Without high-quality data, even the best message can backfire.

Inaccurate data can:

• Tank your email deliverability
• Hurt your domain health
• Waste time on dead numbers
• Trigger compliance risks
• Lead to missed or mis-timed outreach

This risk is rising. Microsoft, Google, and AI-powered inbox filters are tougher than ever on irrelevant or suspicious outreach. But cold outreach can still work – especially when combined with other multi-channel outreach including calls. In Australia and New Zealand, email engagement remains among the highest globally.

Stat check: Email open rates in Australia top 46%, higher than global benchmarks.

But to cut through, you need data that’s accurate, up to date, and locally relevant.

What does “accurate data” really mean? 

At Firmable, we define accurate data as:

• Verified contacts: Emails and phone numbers that actually work
• Real firmographic context: Company size, location, industry, revenue
• Fresh updates: Changes in roles, hiring, funding rounds, tech stack
• Compliance built-in: Especially for ANZ privacy laws and Do Not Call regulations

This level of detail powers more than email – it shapes every touchpoint, from outreach to follow-up.

What accurate data unlocks in your outreach

1. Targeting the right companies

You can’t personalise outreach to someone you shouldn’t be targeting in the first place. Firmable helps you:

• Build lists aligned with your Ideal Customer Profile (ICP)
• Filter by key firmographic traits – like location, headcount, industry, and more
• Use email deliverability filters to avoid bounces and irrelevant prospects

Better targeting = better conversion.

2. Smarter personalisation based on signals

Good outreach isn’t just personal, it’s relevant.

Firmable’s signals (like recent hires, role changes, or expansion events) give you real-time hooks to tailor messaging. For example:

• “Saw you recently raised a Series A – congrats!”
• “Noticed you’re hiring sales reps in Melbourne – we help sales teams like yours book more meetings.”

This goes far beyond {First Name}.

3. Stronger deliverability

Hard bounces kill your sender reputation. Clean data protects your domain health by:

• Avoiding inactive or mistyped emails
• Identifying risky domains or spam traps
• Keeping you off blacklists

Bonus: Clean data is also crucial to comply with local laws, especially around cold calling.

4. Cold calling with confidence

Accurate phone numbers and live data help your reps:

• Call the right person (not someone from a role from 18 months ago)
• Reference recent company moves and activities
• Combine outreach with insight for multichannel impact

Accurate vs inaccurate B2B data: Quick comparison 

Real-world outreach wins: Firmable and customer results 

Let’s talk real-world results – not hypotheticals, not maybes. Just cold, hard numbers from two SaaS companies (including us) that are putting Firmable’s data to serious work.

Example one:  SDR team at Firmable
We like to walk the talk – so naturally, we run Firmable data through our own prospecting engine. Our SDRs consistently hit over 95% mobile accuracy when dialling leads. That means when they pick up the phone, it’s almost always the right number – not some poor soul who just wanted a quiet lunch break.

What happens once they’re connected?
Our call-to-meeting booking rate averages 15–20%.
That’s not a typo.
It means that roughly 1 in 5 conversations turn into a booked meeting. In the world of B2B sales, that’s bananas.

Want more juicy stats? Our blog on SDR metrics breaks down the numbers that matter – from dial accuracy to meeting conversion.

Example two: a Firmable customer levelling up their email game
Another SaaS customer came to us struggling with bounce rates and inbox invisibility. Since switching to Firmable, they’ve seen a 25% uplift in email accuracy. That means more emails landing in the right inboxes, fewer bounces, and a much cleaner CRM.

More importantly, it’s helped them re-engage key segments of their ICP that had gone dark with stale data.

Example three: Firmable’s targeted cold email outreach

We recently launched into New Zealand and were running a series of targeted cold outreach campaigns to drive attendance to our launch event.

68% open rate. 90% click through rate. 2% bounce rate.

What did we do to achieve this?

1. Built the list from Firmable: Focused on a highly targeted ICP segment and overlaid ‘Highly likely’ and ‘Likely’ email deliverability filters.
2. Sent from Smartlead: A tool built for cold outreach using multiple mailboxes and staggered sending tactics (HubSpot and similar CRM tools are only built for warm / opted in prospect emailing).
3. Combined with phone outreach: Let’s face it, emails don’t get replies anymore. But they can help drive brand awareness. Real results come from phone-based follow-ups to get the registration locked in (or meeting or whatever your goal is).

The 2025 cold outreach checklist

To get replies in 2025, smart teams are:

• Using local data that’s live and verified
• Building ICP-targeted lead lists
• Tailoring messages using signals and firmographics
• Combining cold email and calling in sequences
• Tracking what works and iterating

If you’re missing even one of these steps, accurate data is the place to start.

Why teams in Australia and New Zealand choose Firmable

Most B2B data platforms are built for the US. Firmable is purpose-built for ANZ. That means:

• Over 1m verified contacts across Australia and New Zealand
• Real-time firmographic enrichment
• Privacy-compliant filters such as the DNC Register
• A dataset tailored to sales teams, not just marketers

Final thoughts: Good outreach starts with great data

Cold outreach doesn’t start with your message. It starts with your list.

If you’re still relying on generic lead lists or stale CRM data, you’re flying blind. Your message may be great – but if your data’s off, it won’t land.
