Gmail Feedback Loop ID
Gmail requires that you insert a
Feedback-ID header as a prerequisite to
using their Feedback Loop.
You can configure Studio to create this header for emails sent to
subscribers by writing your desired
SenderID to the
/var/hvmail/control/studio.gmail.feedback-senderid file. For example:
echo example-test > /var/hvmail/control/studio.gmail.feedback-senderid
This will cause Studio to insert a
Feedback-ID header in the following format,
given that OrganizationID=13, CampaignID=32, SenderID=example-test:
For autoresponders, this header be in the following format, given that OrganizationID=13, AutoresponderID=47, SenderID=example-test:
If the first line of
blank, or if the file does not exist, then this header will not be written.
Include Feedback-ID to all email addresses
If you would like to include the
Feedback-ID on all email addresses, instead
of only to
@gmail.com, turn on the following flag.
echo 1 > /var/hvmail/control/studio.gmail.feedback-senderid.enable_all_domains
Include Subscriber ID in the Feedback-ID header
If you would like to include the subscriber ID in the
Feedback-ID header, run the following command.
echo 1 > /var/hvmail/control/studio.gmail.feedback-senderid.include_subscriber_id
Google, in their Feedback-ID documentation, advise against usage of this feature. GreenArrow similarly advises against usage of this feature.
When this feature is active, the value of the header will be written in the following format, given that OrganizationID=13, CampaignID=32, SubscriberID=46, SenderID=example-test:
