What are Email Opens, Clicks, and Failures?
Tracking Deliveries
Mobile Locker can keep track of every time your message is delivered to the recipient's email server.
Tracking Opens
Mobile Locker can keep track of every time a recipient opens your messages. Please read this page because Open-Tracking isn't reliable, and you shouldn't put too much stock in it.
Tracking Clicks
Mobile Locker can keep track of every time a recipient clicks on links in your messages.
Tracking Spam Complaints
Mobile Locker automatically keeps track of every time a recipient complains that a message is spam.
Email service providers (“ESPs”) are very sensitive to users clicking on spam complaint buttons, and it’s important to monitor that activity to maintain a good sending reputation. While not every ESP supports Feedback Loop (“FBL”) notifications, we ensure you get data on all those that do. We will remove recipients from future messages if that recipient has filed a complaint. This is necessary to maintain your reputation and not have your emails automatically sent to spam folders.
Tracking Failures
Mobile Locker tracks all delivery failures. Failures include Hard Bounces (permanent failures) and Soft Bounces (temporary failures).
An email message is said to “bounce” if it is rejected by the recipient SMTP server.
With respect to failure persistence, Mobile Locker classifies bounces into the following two groups:
- Hard bounces (permanent failure): The recipient is not found, and the recipient email server specifies the recipient does not exist. Mobile Locker stops attempting delivery to invalid recipients after one Hard Bounce. Mobile Locker will not attempt delivery in the future.
- Soft bounces (temporary failure): Email is not delivered because the mailbox is full or for other reasons.
