Hello @childish-sambino,

Thanks again for the PR!

We appreciate your contribution and look forward to continued collaboration. Thanks!

This has introduced a TS error when sending mails with just templateIds:

const data = {
	from: "someemail",
    to: "somemail",
    templateId: "some sendgrid templateId",
    dynamic_template_data: {randonVariables: "something"},
}

sendgrid.send(data)

Property 'content' is missing in type '{ from: string; to: string | string[]; templateId: string; dynamic_template_data: any; }' but required in type '{ content: MailContent[] & { 0: MailContent; }; }'.

We dont require there to be a body or content as its using a template?

Any ideas?

🤦‍♂ Need more |s.

as @JClackett mentioned, template use case was not included.
anyone working to add the type union in the MailDataRequired already?

[childish-sambino]

@krazibit It was included as part of #1053
