Big Email Delay

We're seeing some similar issues--spoke to Marketo's team, it's an issue they're aware of and working to fix! 

Thanks for letting me know, Josh! Are you having problems with just your large campaigns, or all of them?

I'm not sending anything huge, I'm just trying a few test emails and so far none have come through to my inbox. I assumed it was an IT issue on my end, but now I'm not so sure.

Yeah--we were seeing it with individual tests; tried a few batch campaigns to internal lists to no avail.  Only seems to be affecting a subset of Marketo instances, best I can tell.  

Literally a minute after posting my comment, I received all my test messages at once. Go figure.

Yes our e-mail just sent. Talked to the support team and the engineers are working on identifying the problem. I'll post an update when I hear something especially if it affects future campaigns.

I sent an alert at 11:30 am and didn't receive it until 2:18 pm

No real update here. Support team told us that an email server went down temporarily. Thanks for all of your input.

Hi all,
Since April we have issues with e-mails lagging in delivery, both for ourselves in tests and also for our clients. Delay can reach 24  hours sometimes, and can arrive in bulk.
Has your problems beed solved? What was the solution?
