Acceptable Use Policy

This Acceptable Use Policy (“AUP”) describes activities that are not allowed in connection with your use of the Mail250 Services. The AUP is incorporated by reference in your Agreement with Mail250.

We’ve created our own set of rules to protect the reputation of our clients and their intended recipients. Not only do these rules help us identify spammers, but they also help increase your deliverability and build a strong sending reputation.

If you breach this AUP we may limit, suspend, or terminate your account in accordance with our Terms of Use. We may intercept or block any content or traffic belonging to you or to users where services are being used unlawfully or not in accordance with this AUP.

1. Requirements. Customer will follow these guidelines when sending emails using the Service:

  • a – All email sending metrics to remain within Mail250’s thresholds:
Statistic Thresholds Acceptable levels* Additional details
Bounces ≤ 5% Calculated on the number of messages that have bounced
Unsubscribes ≤ 1.2% or 1% if unsubs > clicks
Blocks ≤ 30% Blocks should be ≤ 30%
Spam Complaints ≤ 0.08% When sending over 1000 but never more than 50 complaints per day
Spamtrap ≤ 1 Spamtrap hits & unjustified abuse complaints

* Mail250 reserves the right to update the parameters of the acceptable sending threshold without prior notice.

  • b – Acquiring or sending to a third-party mailing list is prohibited. Use of contact lists that are bought, rented or scraped from third-parties is prohibited by law in most countries, and is absolutely prohibited on Mail250 servers.
  • c – Emails (unless transactional) can only be sent where permission has been expressly obtained in nature, and can only be sent to recipients who have granted clear, explicit and provable consent to receive communication. This consent should be granted through a confirmed single or double opt-in system that clearly expresses the topic of the subscription on an online or offline form via an unmarked by default checkbox.
  • d – Proof of consent must be provided in the event of an escalated abuse complaint. We take escalated abuse complaints received from recipients very seriously. At any given moment, you must be able to provide information regarding all email addresses to which you’ve sent emails through the platform (including the basis of the obtained consent, when and how the email address was collected, and any other pertain proof of legal permission to contact the recipients).
  • e – An unsubscribe link must be included in every marketing email campaign. All marketing campaigns must include a clear and concise link for recipients to easily opt-out of receiving future communication. The link must be easy for anyone to recognize, read, and understand. You must honor unsubscribe requests without undue delay.
  • f – Sender name and status must be clearly communicated in every email message. “From”, “To” and “Reply-To” fields must accurately and clearly identify the sender’s domain name and email address. When sending from a different domain name on behalf of a partner or related third-party organization, the email body must clearly communicate that the message is sent via a third-party domain.
  • g – Readily publish on your website and comply with a privacy policy that meets legal requirements and include a link to that policy in the body of each email.

Core Statistics defined:

  • Bounces – Much like traditional snail mail, when a destination address cannot accept the incoming package and it gets returned to sender, bounced messages are returned to sender because the recipient address is incorrect or inactive.
  • Unsubscribes – Recipients that opt out of receiving communication because they no longer want to receive communication. There are a variety of reasons customers choose to unsubscribe; some might be that they’re no longer interested in the content you’re publishing or are overwhelmed with a noisy inbox, or your content wasn’t what they were expecting.
  • Blocks – Messages that do not leave Mail250 servers due to a permanent error. These are email addresses that bounced in the past because they are either non-existent or invalid, or previously reported your message as spam. This also includes email addresses that resulted in complaints from recipients or did not pass through Mail250’s spam filters.
  • Spam Complaints – Number of recipients that marked your message as spam.
  • Spamtrap Hits – After a certain amount of inactivity, webmail providers turn email addresses into spam traps to catch senders that are using outdated lists or lists purchased, and/or obtained from third-party companies.
  • Unjustified Abuse Complaint – When a recipient reports a sender for messaging without their consent.

2. Prohibited Content

4. Excessive Use of Shared System Resources

You may not use any shared system provided by Mail250 in a way that unnecessarily interferes with the normal operation of the shared system, or that consumes a disproportionate share of the resources of the system. For example, we may require you to repair coding abnormalities in your application if it unnecessarily conflicts with other Mail250 customers’ use of the Services. You agree that we may quarantine or delete any data stored on a shared system if the data is infected with a virus, or is otherwise corrupted, and has the potential to infect or corrupt the system or other customers’ data that is stored on the same system.
