3. Email-Specific Requirements

All emails sent through the Mail.Land platform must comply with the following requirements:

3.1 Permission-Based Sending

You may only send emails to recipients who have given explicit, verifiable consent (opt-in) to receive communications from you. Double opt-in (confirmed opt-in) is strongly recommended and may be required for certain sending volumes or use cases. Pre-checked consent boxes, implied consent through unrelated transactions, and consent bundled with other terms do not constitute valid consent under this AUP.

3.2 Working Unsubscribe Mechanism

Every marketing and promotional email sent through the Service must include the following:

  • A clearly visible, functional unsubscribe link that allows recipients to opt out of future communications easily.
  • Unsubscribe requests must be honored within 10 business days. Prompt processing is expected and delays may trigger enforcement action.
  • A one-click unsubscribe header (List-Unsubscribe) is required for all marketing emails to support mailbox provider unsubscribe mechanisms.

3.3 Accurate Sender Identification

All emails sent through the Service must accurately identify the sender. Specifically:

  • The "From" address must be valid, monitored, and capable of receiving replies.
  • A valid physical mailing address must be included in all commercial emails as required by the CAN-SPAM Act and equivalent regulations.
  • Sender spoofing, impersonation of other individuals or organizations, and the use of misleading header information are strictly prohibited.

3.4 Bounce Rate and Complaint Thresholds

Maintaining healthy sending metrics is a condition of using the Service. The following thresholds apply to all accounts:

  • Hard bounce rate must remain below 5%.
  • Spam complaint rate must remain below 0.1% (1 complaint per 1,000 emails).

Exceeding these thresholds may trigger automatic sending throttling, temporary suspension, or further enforcement action as described in Section 5. MailLand monitors these metrics continuously and will notify you when thresholds are approached or exceeded.

3.5 List Hygiene

Customers are responsible for maintaining clean and up-to-date mailing lists. This includes:

  • Regularly cleaning mailing lists to remove invalid email addresses, role-based addresses, and known spam traps.
  • Promptly removing hard bounces and unsubscribed recipients from active lists.
  • Never re-adding recipients who have previously unsubscribed from your communications.
  • Using email validation and verification tools before importing new lists into the Service.

4. Prohibited Actions

In addition to the content restrictions outlined in Section 2, the following actions are strictly prohibited when using the Service:

  • Using purchased, rented, borrowed, or scraped email lists from any source. All recipients must have provided consent directly to you.
  • Harvesting email addresses from websites, online directories, or social media platforms using automated tools, bots, or scraping software.
  • Using email addresses obtained without the recipient's knowledge or explicit consent, including addresses obtained through co-registration without clear and prominent disclosure.
  • Attempting to circumvent, bypass, or disable spam filters, rate limits, sending quotas, or other security measures implemented by MailLand or recipient mail servers.
  • Engaging in traffic pumping or artificially inflating email volumes to generate fees, consume resources, or manipulate service metrics.
  • Sending test emails to real recipients without their prior consent.
  • Using the Service to send emails on behalf of third parties without clearly disclosing the relationship between you, the third party, and the recipient.
  • Creating multiple accounts to circumvent sending limits, enforcement actions, account suspensions, or any other AUP restrictions.
  • Reselling, redistributing, or sublicensing the Service or any part thereof without prior written authorization from MailLand.
  • Using the Service to perform network abuse, including but not limited to denial-of-service (DoS) attacks, distributed denial-of-service (DDoS) attacks, port scanning, or unauthorized access attempts against any system or network.
  • Interfering with, disrupting, or degrading the integrity, performance, or availability of the Service or MailLand's infrastructure, including the systems and networks of other MailLand customers.

Appeals must include a detailed explanation of the circumstances and any corrective measures taken. All appeals are reviewed by the trust and safety team, and we will respond with a decision within a reasonable timeframe. MailLand's decision on appeals is final.
