Accurate DNS records contribute to your domain’s health and help earn a positive sender reputation. 

#2 Helps with email authentication

When you send an email, the recipient’s email servers perform DNS checks to ensure that your sender domain is legit.

#3 Helps your emails to pass spam filter checks

Proper DNS settings reduce the chances of being rejected or flagged by email providers or spam filters.

#4 Helps your email account to avoid blacklists

Sending domains without valid DNS records are more likely to be listed on blacklists.

#5 Keep your bounce rate low

Emails sent from domains with fully configured domain records are less likely to get delivery errors.
