Do you know that before sending your first campaign it is good to verify your sending domain. In this way you can make most of your emails to go to inbox!
Go to Sending Domains > Create new sending domain > and write your domain from which you send. After that the system will create 2 TXT values. The first one TXT value is your DKIM sign, the second one is your SPF sign. You need to add these values to the DNS of your domain at your control panel of your website (usually cPanel). If you are not sure what is this contact your host administrator of your website. If you are not sure what is this contact your host administrator of your website.
