Issues with ReadyTalk Webinar Email Deliverability

[Anonymous]

I have a ReadyTalk webinar synced with a Marketo program. We are sending all confirmation emails through our own template in Marketo. We didn't experience any problems until yesterday, when I noticed more and more emails had a failed deliverability. The emails were listed as 'soft bounce.' I don't believe our email message is too large, as we have been able to send them successfully in the past.

As a work-around I went into ReadyTalk and manually sent the confirmation email to all the affected registrants.

Is this a known issue? Has anyone else had trouble with this?

Was all confirmation emails soft bounced?
Is your confirmation email set as operational? (i.e. no unsubscribe link)

Only 8 out of 100 confirmation emails were soft bounced. I just spoke with Support and they notified me that the soft bounces were due to a temporary IP listing on the spamcop blacklist. He said this has been lifted and should no longer affect our program. I'll keep an eye on it!
