Is there any way that CC could add this to the header? X-Auto-Response-Suppress: All
If there was a checkbox in the header options that allowed us to add this to a campaign, it would help prevent email storms and possibly resolve a lot of auto-reply issues. Again, it would have to be an individual choice to suppress all auto-replies.
Unfortunately, at this time that is not a feature we offer. But I would be happy to submit this as a feature request to our developers! Thank you for bringing it to our attention! Please let us know if you have any other questions.
