CASL

What it means

Canada's Anti-Spam Legislation, which asks for consent before commercial electronic messages are sent.

Consent can be implied when a business has conspicuously published its email address, hasn't said it doesn't want messages, and your message is relevant to its business (section 10(9)).

Why it matters here

NoSite Leads is our editorial choice for finding local businesses without websites: it scans a UK postcode, US ZIP code or Canadian postal code and marks every business with no website listed, with its phone number.
