Sending emails
Set up email properly to ensure that your emails look professional, are properly authenticated, and avoid spam filters. To send emails from your company’s domain (e.g. support@yourcompany.com) through Plain, you'll need to update your domain’s DNS settings.
What you'll add
During setup, you’ll be asked to add two DNS records:
DKIM (DomainKeys Identified Mail)
Authenticates that you are the real sender.Return Path (CNAME)
Sets where bounce notifications should go, so Plain can handle them reliably.
You’ll copy these values from the Plain dashboard – and paste them into your DNS provider’s dashboard.
