What is Email Consent?

Email consent is permission given by an individual to receive electronic messages from your organization. Sending emails without proper consent violates international anti-spam laws and Mailofly’s Acceptable Use Policy.
The recipient has taken an affirmative, unambiguous action explicitly requesting to receive your emails.
  • Examples: Checking an un-checked box (“Sign up for our product newsletter”), entering their email into a subscription form labeled “Get weekly tips”.
  • Standard: Explicit consent is required by GDPR (EU), CASL (Canada), and Mailofly policies.
The user has an existing business relationship with you (e.g., they bought a product or created an account).
  • Allowed: Transactional receipts, account alerts, password resets, critical service notices.
  • Not Allowed: Promotional newsletters or marketing campaigns cannot be sent under implied consent without an opt-in.

​
Single Opt-In vs. Double Opt-In

  • Single Opt-In (SOI): User submits form and is immediately added to the active mailing list.
  • Double Opt-In (DOI): User submits form, receives a verification email with a confirmation link, and is only added once clicked.
    • Why DOI is Superior: Prevents bots, fake emails, and malicious signups from polluting your audience list and causing hard bounces.
  • Purchasing or renting an email list.
  • Scraping emails from LinkedIn, company websites, or public directories.
  • Pre-checked checkboxes on signup forms.
  • Co-registration partnerships without explicit disclosure.
