send email campaign


I want to send an email campaign but here the message out
You are required to verify your sending domain( in order to be able to send this campaign!
Please click Ici to add and verify domain name. After verification, you can send your campaign
thank you for helping me to succeed my campaign
Just faced same issue. when I click the link (customer/sending-domains/create) then it just points to customer dashboard
Solved it by selecting NO on Must verify sending domain *.
I think the sender domain is already verified through SMTP service, so why we need this?
