We encountered a situation where we scheduled an email to be sent at 10 AM EST, but after scheduling it, the schedule tab showed as 'not run' and there was no tick marked for the smart campaign either. When we revisited the smart campaign after half an hour, we observed that the email had been sent at 10:24 EST.
Similarly, there was another instance where a team member scheduled the email again since the schedule tab had shown as not run.
Can anyone please let me know why does this happen?
Were you sending to a large list? I've noticed delays when sending to a large list.
Also, have you tried using an email program vs. a smart campaign? In my experience, email programs seem to run on time more so that smart campaigns. Especially if you use the head start feature.
First of all, the time shown in the schedule tab is not the email delivery time or send time; it indicates the last run time, which is the most recent time the campaign was executed. You may look at the run history to see when your campaign completed.
Did you check your campaign queue? Do you have a lot of trigger campaigns running, or is there a long queue? That might be the reason your email campaign did not start at the time you scheduled but started 4 minutes later.
Another reason, as @kaylaB22877 mentioned, could be that your smart list criteria are too long or have complicated logic, which can cause the campaign to take longer to run.
Hope this helps!
@MuhammedSuhail Is this possibly related to the issue Adobe had (is still having?) with a bunch of their email addresses being blacklisted?
Is this a problem you've been seeing for a long period of time, or just a few days?
We noticed this issue recently, but there are a couple of scenario we came across with it for random campaigns.
All email got delivered after sometimes.
