When does a mailing count as opened?
Tracking which mailing has been opened is done by calling an invisible image and a CSS file, which are located directly on our servers. A mailing is also marked as opened, when the recipient clicks on a link in the mailing.
The recipient has enabled their e-mail software to display images
The mailing immediately counts as read once the recipient opens it.
The recipient has disabled image display in their e-mail software
The mailing only counts as read if:
- The recipient manually sets their e-mail software to display images
- Or, when the recipient clicks on a link in the mailing.
