We use Postmark to improve the reliability, security, and deliverability of emails sent from Sintel Apps.

Why do we use Postmark?

Postmark is a specialist transactional email service designed for sending important application emails.

Email sender address

Emails sent from Sintel Apps are sent from:

Sintel Apps: <noreply@mail.sintelapps.com>

If your organisation uses mailbox rules, allowlists, or spam filtering based on sender addresses or domains, you may need to ensure that emails from mail.sintelapps.com are permitted.

What information is shared?

To deliver emails, the following information is transmitted to Postmark:

• Recipient email address
• Email subject
• Email content
• Delivery information, such as successful delivery, bounces, and spam complaints

This information is processed solely for the purpose of delivering emails and maintaining the reliability of our email service.
