As Vercel is a platform focused on deployments, it does not provide a mail service for domains purchase with or transferred into it.
Because many domain providers do not offer a mail service, there are a number of third-party services that specifically offer this type of functionality and are enabled by adding DNS records.
You can use the DNS UI to add a preset for common mail services.
If your email provider is not in the list of presets, you can proceed to next section where we will discuss adding records manually.
While the DNS UI does have a preset for G Suite, it will serve as an example in this article. You can consult the documentation for G Suite here.
1. First you need to insert the MX records related to your service:
You will likely need to repeat this step multiple times, depending on the number of records your provider requires you to add.
2. The second step is to verify the domain. G Suite is requiring a TXT record so we can verify the domain.
In this case, the TXT should be in the root domain and that is why the
'name' field is empty. You need to check the required arguments with your mail provider.
