Sending policies

Technical Information for Postmasters

  • Identification (MAIL-FROM): The envelope-sender (Return-Path header) is unique to each MailUp Platform user. A MailUp Platform user cannot change this address. This uniqueness allows you to block a specific spammer without affecting other legitimate users.
    • Example A: Return-Path: customer001@bounce.musvc.com
    • Example B: Return-Path: customer002@bounce.emailsp.net
  • Blocking a User: By blocking the specific envelope-sender (MAIL-FROM), you will block only the user that is sending SPAM.
  • Intervention: If a MailUp Platform user is sending unsolicited messages, we may intervene from our side as well. Please inform our Compliance Team by writing to abuse@mailup.com.
  • Receiving policies that are exceeding RFCs: none.

MailUp Platform Anti-SPAM Policy

  1. No SPAM

Spam is any commercial message sent without the recipient’s permission. Commercial email is defined as any electronic mail message whose primary purpose is the commercial advertisement or promotion of a product or service. The Service is intended to be used for the sole and exclusive purpose of sending messages to recipients who have agreed and confirmed to receive such messages. Your account may be immediately suspended or terminated if You send SPAM.

What’s TeamSystem Policy against Spam?

Spamming is the abuse of electronic messaging systems to send unsolicited bulk emails (Spamhaus definition). It is illegal in many countries.

Please note that TeamSystem doesn’t share, sell or rent any email addresses.

We are not responsible for the data imported into the system by users of the MailUp Platform, and are not authorized to reveal or modify any data stored in our servers.

Users of the MailUp Platform agree to comply with a very strict Anti SPAM policy. If any MailUp Platform user is found to be sending SPAM, their account is immediately suspended, it is terminated if additional research confirms the initial findings.

Consistently with this goal, TeamSystem – directly or through our partners and resellers – enforces a strict, no-tolerance policy against SPAM, beginning with a customer vetting process based on M3AAWG’s Best Practices and systematic monitoring of all account activity.

  1. Monitoring and customer vetting

TeamSystem monitors the use of the Service to ensure that it is in compliance with this policy and may suspend or terminate the account in case of violations. This action will be taken with no legal injunction or notice, but may be followed by additional legal actions in order to exempt TeamSystem from any responsibility related to the misuse of the Service.

In addition to monitoring the activity of current customers, We pre-qualify new users of the Service with the objective of building a community of selected users of first-class ranking. TeamSystem’s customer vetting process is based on M3AAWG’s Vetting Best Common Practices. We have no intention to acquire a new customer that intends to misuse the Service to send unsolicited messages, as this can hurt our network operations and reputation.

  1. Relationship with ISPs

Over the years We have built strong relationships with many of the world’s leading ISPs (Internet Service Providers) and Blocklists. With them We keep sharing information regarding policies, practices and potential issues. Any ISP, mail or blocklist administrator intending to assist us to provide a better service or to ask for our cooperation is very welcome to do so: please email us at abuse@mailup.com.

  1. Rule of conduct

You may never send SPAM by using the Service. Specifically, you may not:

  • Harvest emails from websites
  • Purchase or rent lists (whether they are opt-in or not)
  • Perform email appending
  • Send messages that are unrelated to what subscribers signed up to receive
  • Add an email address into a list without the subscriber’s permission
  • Send messages to someone who has requested to be removed from the list

You may:

  • Send a commercial message to a recipient who has double opted-in (or confirmed opted-in) to receive it.
  • Send a commercial message to a recipient who has single opted-in to receive it (though we strongly encourage double opt-in).
  • Send transactional messages (password reminders, order confirmations, etc.).

TeamSystem requires Customers to obtain authorization to receive communication from the recipients in a clear and transparent manner. Moreover, recipients must be given the possibility to revoke their authorization at any time (unsubscribe) easily and free of charge.

  1. Determining whether you send SPAM

To determine whether You have sent SPAM we will:

  • Review the content of the message.
  • Review Your subscriber list for patterns common to harvested/purchased lists.
  • Review SPAM complaints and monitor the complaint rate (rates above 0.1% are typically an indicator of unsolicited messages).
  • Monitor the total number of complaints.
  • Review subscription records (timestamp and IP of subscription).

Proof of sending SPAM includes:

  • Listing of your IPs or domains in Relay Block Lists (SPAMHAUS, SURBL, URIBL, SORBS, SPAMCOP, etc.).
  • Blocklisting by an ISP.
  • High rate of complaints or hard bounces.
  1. No refunds

In the event that Your MailUp console account is terminated due to violation of this Anti-Spam Policy, You will not be refunded any amounts that have been paid towards the use of the Service.

  1. Other information for message recipients

We encourage any subscriber to an email list to always review the sender and subject line and delete unsolicited messages without downloading content to avoid phishing risks. We intend to protect the legitimate interests of recipients of e-mail messages with regard to unsolicited communications for direct marketing purposes.

  1. Your privacy is protected by TeamSystem

The sender of the email you received entered an agreement with TeamSystem to use MailUp. As part of this agreement, they agreed to comply with strict Anti-SPAM policies, meaning they are only allowed to send messages you signed up to receive.

  • How to unsubscribe: Click on the unsubscribe link in the footer or header of the email. If the link is missing or broken, report it to our Compliance Team.
  • Data Protection: TeamSystem doesn’t share, sell or rent any email addresses. We are not responsible for the data imported into the system by users, but we enforce strict policies to prevent abuse.
