Kinsta hosting plans do not include an email service. However, we can recommend some third-party email service providers for you to set up your email. You can find more details in our help article here: Tools - Email - Kinsta® Docs.
When setting up an email account, your chosen email provider will usually require DNS records to be set in your preferred domain’s DNS manager. You can choose to keep your domain’s DNS managed by your DNS registrar, or let Kinsta manage your DNS. If you choose Kinsta to manage your DNS, you can refer to our help article here for more details Domains and DNS - Kinsta's DNS - Kinsta® Docs.
