Sequence Error Slot unvailable

I have a sequence with two mails.

First mail was sent but I have a error for few user : The desired email sending time slot is unavailable

Do you hnow what that error means ?

Thanks

Hey @SMALIZIA

Can you share the screenshot of the error so that I have a clear understanding of what issues you are facing with your sequence?

Hey @SMALIZIA

maybe the time zone or the date and time set to send those emails is not available or recommended

check again in the email configuration

Just in case here is an article with the main errors encountered in sequences

Hope this helps
