Emails sent from Sintel Forms to internal users come from: and emails sent from Sintel Forms to external users come from
The steps to customising the send-from emails differ depending on whether or not these emails are going to internal or external users.


How to Customise Send-From Address for external users:

Normally emails sent by Sintel Forms to External Users come from the following address however, customers can also provide a specific email address to use when emailing External Users.

To activate this feature, you simply need to contact us at and provide the email account credentials – the credentials are then encrypted and stored safely. When the configuration is completed, all external emails sent by Sintel Forms will be sent from the email address you provided.

If you are considering using this feature we recommend using an app password to avoid using your real password in the configuration. App passwords are generated automatically and should be used for a single purpose, you can read more about them here.

This feature only applies to emails sent from Emails sent from Site Name (such as emails sent by the Sintel Forms Workflow or Conversations features) can not have the from address changed.


How to Customise Send-From Address for internal users:

Emails sent from the address, such as those generated by the Sintel Forms Workflow or Conversations features, previously had a fixed “from” address due to SharePoint limitations. A solution is now available to personalise the sending-from address according to your preferences. However, it’s important to note that this solution still has its limitations, as it cannot be specific to individual sites. If you choose to make these changes, all Microsoft messages from your organisation will come with this custom sending-from domain address, so it’s important you don’t make it site specific.

Follow these straightforward steps to personalise the send-from address:

  1. Access Microsoft 365 Admin Centre: Open the Microsoft 365 admin centre and log in to your account.
  2. Navigate to Organisation Settings:
    • Click on “Show all” on the left-hand menu.
    • Select “Settings” and then “Org settings.”
    • Choose “Organisation profile” from the list.
  3. Configure Email Notification Settings: Scroll down to the “Send email notifications from your domain” section.
  4. Enable Custom Send-From Domain:
    • Toggle on the option labelled “Use a custom send-from domain address.”
    • A new field will appear. Enter your desired prefix, such as “no-reply,” or any other term you prefer.
  5. Save Changes: Click “Save” to apply the changes.

Now, emails sent by Sintel Apps, including those from the Sintel Forms Workflow or Conversations features, will display the customised send-from address you specified.


Important Notes:

  • This solution is not site specific, all Microsoft messages from your organisations will come with this custom send-from domain address, so it is important you don’t make it site specific. However, to help recipients easily identify the source of the email, we recommend including the app’s title within square brackets in the subject line when composing emails in the Sintel Forms Designer. For example, [Expenses App].
  • The email address you enter as the custom send-from domain does not need to exist as a mailbox. However, if you prefer, you can choose an existing real email address.

We hope this customisation feature enhances your experience with Sintel Apps. If you encounter any issues or have further questions, please don’t hesitate to reach out to our support team.

Thank you for choosing Sintel Apps!
