5. Mailbutler’s Snooze and Send Later Functionality

5.1 How does Mailbutler’s Snooze and Send Later Features Work?

Mailbutler enables you to mark emails that you'd like to have returned to the top of your inbox at a later time (Snooze) or to schedule an email to be sent at a specific date and time (Send Later). If you activate the Snooze or Send Later feature for a specific email, Mailbutler will move the email from the inbox folder to the Mailbutler-Snoozed or Mailbutler-Scheduled folder on your email server. At the end of the Snooze period, Mailbutler moves the email from the Mailbutler-Snoozed folder back to your inbox. At the end of the Send Later period, Mailbutler moves the email from the Mailbutler-Scheduling folder to your outbox. Your email server automatically sends this email.

5.2 What data is collected?

In order to guarantee full functionality of Mailbutler’s Snooze and Send Later features we may collect and store certain information about the recipient email address, message subject and message ID (RFC 2392) when you use Snooze or Send Later. But we never collect and store the message content of your emails. We temporally collect and store user authentication information of your email server for the Snooze and Send Later period. We use OAuth for user authentication (wherever possible) which gives us access to your data without letting us know your password. We only collect and store this information temporally when you use the snooze or send later feature and only for the time the features are active.

6. Mailbutler’s E-Mail Opened Confirmation Functionality (Email Tracking)

6.1 How does Mailbutler’s Email Tracking Work?

Mailbutler enables mail senders to see when, where, how often and on which device the recipient has opened an email. If the sender activates the email tracking for a specific email, Mailbutler includes a hidden image (also referred to as web-bug or 1-pixel image) with a unique mail-ID into the outgoing mail. Once the recipient opens the email, the recipient’s mail client or web service sends a request to our server in order to load the hidden image. Our servers collect and store the mail-ID, IP address, email client information, device information and the date and time of such request. We pass on the date/time, IP address, email client information, device information and mail-ID to the Mailbutler software of the sender where it is linked to the specific email and enables the Mailbutler software to display the read date/time, IP address, email client information, device information and location based on the IP address.

6.2 What data is collected?

Through Mailbutler’s email tracking the sender obtains the information when the recipient opened the email. We only store the mail-ID, meta information (recipients, CC & BCC email addresses) and subject line together with the corresponding opened date/time, device information and the recipient’s IP address. We do not collect further data.

6.3 Who is responsible?

The sender of an email using Mailbutler’s email tracking functionality may collect, process and use personal data. It is the sender’s responsibility to ensure that the use of the email tracking functionality is in compliance with any laws applicable to the sender, in particular data protection laws. This may require the sender to inform the recipient about the tracking, to offer an opt-out or to obtain prior consent.

6.4 How can the Recipient avoid Email Tracking?

Recipients can configure their email client (e.g. Outlook) or web service (e.g. googlemail) so that by default images contained in emails are not loaded. Please see the configurations menu and manual of your email client or web service for details. Alternatively, you can contact the sender and object to any future email tracking.
