Acceptable Use Policy
This Acceptable Use Policy (“AUP”) describes activities that are not allowed in connection with your use of the Sinch Email Services. The AUP is incorporated by reference in your Agreement with Sinch Email.
The Internet is still evolving, and the ways in which the Internet may be abused are also still evolving. Therefore, we may from time to time amend this AUP to further detail or describe reasonable measures, restrictions or conditions on your use of our Services by publishing a revised version of the AUP at https://www.mailgun.com/aup, or in the event of a material adverse change to the AUP, by providing you thirty (30) days written notice.
The determination of whether and to what extent a customer’s act or omission and is in violation of this AUP will be made at our sole discretion.
Customer will follow these guidelines when sending emails using the Service:
1a – All email sending metrics to remain within Sinch Email’s thresholds:
Calculated on the number of messages that have bounced
or 1% if unsubs > clicks
Calculated on the number of messages that have been reported as spam
Calculated on the number of messages that have been blocked
*Sinch Email reserves the right to update the parameters of the acceptable sending threshold without prior notice.
1b – 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 Sinch Email servers.
1c – Emails and SMS (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.
1d – 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 and/or telephone numbers to which you’ve sent emails and/or SMS through the platform (including the basis of the obtained consent, when and how the email address or telephone number was collected, and any other pertain proof of legal permission to contact the recipients).
1e – 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. Note that transactional and confirmation emails and SMS do not require an unsubscribe link.
1f – 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. Any third-party domains must also be validated by the sender.
