What exactly is in the download?+

A row per business with name, phone, full street address, postal code, website URL, parent domain, Google rating, review count, and the email address where one was found — as CSV, XLSX and JSON. 0% of the emails here are corporate-domain rather than webmail. The five-row preview above is drawn live from the file you will receive.

Can I use this list for cold email outreach under CASL?+

These are publicly-listed business contacts, not an opt-in email list. CASL's implied-consent provision for published business addresses is narrow, and whether it covers your message is a legal judgment. Buying this list is not a compliance guarantee and this is not legal advice — you are responsible for evaluating CASL and any other applicable law, and should talk to a lawyer if you are unsure. Our Compliance & Responsible Use page sets out the rules.

/ HelpCommon Questions

How do I choose a reliable marketing agency in Port Colborne?+

Start with the rating — look for a marketing agency holding 4.5 stars or higher with a healthy number of recent reviews, which signals consistent, current service. Confirm they're properly licensed and insured for the work you need, and read a few reviews to see how they handle problems, not just praise. The listings below are sorted by Google rating to make this easier.

What's the typical cost of a marketing agency in Port Colborne?+

Pricing varies widely by the scope of the job, materials, and how urgent the work is, so there's no single rate. The most reliable approach is to contact two or three marketing agencies directly for a quote on your specific situation. Use the "View on Google Maps" or "Visit Website" buttons on each listing to reach out.

Are these marketing agencies verified?+

Yes. Every listing is sourced from public Google Business Profile data — business name, rating, and review count — and refreshed monthly so closed or relocated businesses drop off. We show only what's already public; we don't add or alter business details.

How can I contact a marketing agency?+

Click "View on Google Maps" to get directions, hours, and the business's public contact options, or "Visit Website" to reach them online. We don't publish private phone numbers or email addresses here — the business's own Google profile and website are the right place to get in touch.

I'm a business owner — how do I update or remove my listing?+

Email support@publicleads.com with the subject "Removal Request" and include your business name and city. We process removal and correction requests within 48 hours.
