Anti-Spam Policy

Last Updated: February 20, 2026

Our Commitment to Anti-Spam

MailSequence takes a zero-tolerance approach to spam. We built our platform to help legitimate businesses conduct personalized, permission-based email outreach—not to facilitate mass unsolicited emails.

We comply with CAN-SPAM Act, GDPR, CASL, and other international email regulations. We expect all users to do the same.

What is Spam?

Spam is any unsolicited commercial email sent to recipients who have not given explicit permission to receive communications from you. This includes:

  • Emails sent to purchased, rented, or scraped email lists
  • Emails sent without a legitimate prior business relationship or consent
  • Emails that do not include a clear unsubscribe mechanism
  • Emails with deceptive subject lines or sender information
  • Emails that continue after a recipient has opted out

Prohibited Practices

The following practices are strictly prohibited on MailSequence:

List Acquisition

  • Purchasing or renting email lists
  • Scraping emails from websites, directories, or social media
  • Using email lists without verifiable consent
  • Sharing or selling email lists obtained through MailSequence

Content & Sending

  • Sending emails without a working unsubscribe link
  • Using misleading subject lines or sender information
  • Concealing the commercial nature of emails
  • Continuing to email after an opt-out request
  • Sending malicious content (malware, phishing, fraud)

Technical Violations
