The Email Studio runs with your workspace's access. Launch it from your Sigmix dashboard and it opens ready to use.
Go to your dashboardPick a list to import contacts into, or create a new one.
Send campaigns from your own domain (e.g. mail.yourbrand.com) for the best inbox delivery. Add a domain below, add all the DNS records it returns at your DNS provider, then click Verify. Two things are checked: the Amazon SES records that make the domain deliverable, and a _sigmix ownership record that proves the domain is yours — both are required before you can send from it.
