A feedback loop is a system that allows email service providers to report to the sender about the status of the messages they have sent. In our case, the sender is us - sending emails on your behalf. The feedback can include information about whether the message was delivered, opened, or marked as spam by the recipient. Feedback loops are used to help email senders improve their email delivery rates and ensure that their messages are being delivered to the intended recipients. They can also be used to help identify and address any issues that may be causing messages to be marked as spam or not delivered.
What inbox providers offer feedback loops?
Many major email service providers, including Gmail, Yahoo, and Outlook, offer feedback loops to senders. These feedback loops allow senders to receive information about the status of their messages and help them improve their email delivery rates.
In addition to the major email service providers, many smaller inbox providers also offer feedback loops to senders. Some examples include Zoho, Fastmail, and ProtonMail. It's worth noting that not all email service providers offer feedback loops, and those that do may have different policies and procedures for how they operate.
How does a feedback loop work?
A feedback loop typically consists of a series of automated messages that are sent between the email service provider and the sender. When an email is delivered, opened, or marked as spam by the recipient, the email service provider will send a message to the sender to report this information.
Here's an example of how a feedback loop might work:
- The sender sends an email to a recipient;
- The email service provider receives the email and delivers it to the recipient's inbox;
- The recipient opens the email;
- The email service provider sends a message to the sender to report that the email was successfully delivered and opened.
In this example, the sender would receive a message from the email service provider indicating that the email was delivered and opened by the recipient. This information can be used by the sender to improve their email delivery rates and ensure that their messages are being delivered to the intended recipients.
