Cold email to Co-Founder contacts in Australia is governed by Spam Act 2003 (Spam Act 2003 + Privacy Act 1988 (Cth)). Commercial emails require consent, but 'inferred consent' applies when a business email address is published on a website or business card without a prohibition on unsolicited contact. Unsubscribe is mandatory in every commercial message.
Opt-out window: 5 business days
Permitted with proper unsubscribe mechanism. Consent recommended for individuals at companies under 10 employees.

Yes, under inferred consent. Australia's Spam Act 2003 permits cold email to business contacts when their email address is publicly available (e.g., on a company website or LinkedIn profile) and no prohibition on contact has been stated. Every commercial email must include a functional unsubscribe mechanism, and opt-out requests must be honoured within 5 business days.
Co-Founder titles average a 4% reply rate in B2B cold email campaigns (Woodpecker Cold Email Study 2024). Adjusted for Australia market conditions, campaigns typically see a 3.9% reply rate. Sequence length, subject line quality, and personalisation depth all influence the final rate.
Quarvio runs SMTP verification immediately before order delivery — not at the time the database is compiled. This means each Co-Founder contact is tested against the live mail server at the moment you order. Contacts that fail verification are replaced. The result is a typical bounce rate below 3%, compared to 25-35% on unverified Apollo exports.
Quarvio maintains Co-Founder coverage across Australia with a focus on the leading B2B cities: Sydney, Melbourne, Brisbane. Volume varies by industry — technology, financial services, and professional services tend to have the highest Co-Founder density. Contact us before ordering to confirm availability for your specific ICP.
The highest-performing Co-Founder subject lines are company-specific, short (4-7 words), and avoid generic phrases. Tested examples from the Instantly benchmark study: "Quick question about [Company]'s growth stack" and "How [Similar startup] is 3x'ing their outbound pipeline". Subject lines referencing a recent company event outperform generic ones by 2-3x in Australia.
