Hey, 

Facing issue with not able to send emails. We are working welcome email series but when i add the email list most of the emails are going in missing topics. So i'm not able to send them emails. Can you please advise whats the issue?

I have my email list ready. Mapping is done. workflow is good because some emails sent successfully. So what's the issue with other one. 

Please help me asap.

Thanks,

Garry
