Email service DNS records now work on Playcode domains

You can now connect email services like MailerLite, SendGrid, Mailchimp, Klaviyo, and Postmark to a domain managed by Playcode.

These services verify your domain with DKIM records: CNAME records whose target contains an underscore, such as litesrv._domainkey.mlsend.com. Playcode's DNS editor rejected those targets as invalid, which blocked email authentication. Underscores are now accepted in CNAME, ALIAS, NS, and MX targets, so you can add the records exactly as your email service shows them.
