Each week we export our Status Log from our email campaign to check our Delivery Statistics and fix email addresses as needed. Starting June 2nd, I’ve noticed in the term “Undeliverable” in the Send Status column instead of “Bounce.” I can’t find any reference to “Undeliverable” in either of the following help articles:
So, my assumption is that Survey Gizmo has just changed the term and hasn’t had time to update the Help articles. But is there any technical difference between an email that Bounced, vs an email that is Undeliverable?
I’m pretty sure it’s the same thing, but if anyone out there knows if there’s a difference, please let me know. Thanks so much.
I noticed that all of the undeliverables in my file are aol.com addresses. Bounces are from lots of different email providers, but aol addresses seem to be the only ones deemed “undeliverable.” Are you experiencing the same thing or something different?
I wanted to reach out and hopefully offer some additional clarity regarding this thread.
This undeliverable status will appear only for aol.com email addresses (it is a status that is returned to us from AOL via the status log). This is effectively a bounce.
AOL throttles delivery such that there are limits on the number of emails that can be sent for a specific message from a specific domain to their servers per hour and per day. If you exceed the limit, AOL may fail to deliver your email.
The best way to get around this is to restrict the number of aol.com email addresses per campaign message or to consider breaking large lists of these addresses into smaller batches and sending in waves. This could potentially help improve your deliverability but we can’t make any guarantees.
Thank you all for the information that you have provided via this thread!

I’ve noticed the same thing for my June and July mailings. The aol.com addresses have a status of “Undeliverable”, so they don’t show up in the Delivery Statistics.
SG says that they’re only temporary greylisted and that they keep trying, but I’m skeptical. I do mailings towards the end of the month, then reminders 1 and 3 weeks after that. The first time undeliverables I have are reminders sent on June 7. Some AOL addresses were successfully sent, and some were undeliverable. Of the undeliverables, some were successfully mailed during the second reminder. So that seems to verify that the greylisting was only temporary.
But when I mailed on June 21, all the AOL addresses were undeliverable for all 3 mailings. So I wonder if AOL has permanently blacklisted SG.
