What RadiusPilot adds to every email

  • Your business name and postal address, then this line: Don’t want emails like this? Reply “unsubscribe” and we won’t email you again.
  • A List-Unsubscribe header on outreach, when the email goes out right away
  • A block on every address in your opt-out list, also when you copy an email to send elsewhere
  • A stop at your daily limit, counted in people

Every email gets the line, emails to your clients too. It can’t be switched off, and it’s added even when a template has its own unsubscribe link. The Windows app refuses to send an email without it.

What stays your job

  • Add your business’s postal address in Settings › Email. It starts empty, and outreach from your mailbox waits until it’s there
  • Add everyone who asks to stop to the opt-out list
  • Write to businesses about things that relate to their work
  • Keep a record of where you found each address. Published contacts saves the page and the date with the address you use

Canada: CASL

Canada’s anti-spam law covers commercial email received in Canada, wherever the sender is. You need consent. Implied consent can cover an address a business publishes conspicuously, without saying it doesn’t want unsolicited email, when your message relates to its business or the person’s role. Guessed or harvested addresses don’t have it.

United States: CAN-SPAM

CAN-SPAM lets you email businesses without prior consent. The email must not mislead. It must say it’s an ad when it is one, include a valid postal address, and offer an opt-out that you honour within 10 business days.

Other places

Rules differ elsewhere, and Europe’s are much stricter. Check before you write to businesses outside Canada and the United States.
