Send an Email
// Add this to your Replit project

export async function sendSignupEmail(to: string) {
const response = await fetch("https://api.xmit.sh/email/send", {
method: "POST",
headers: {
"Authorization": `Bearer ${process.env.TRANSMIT_API_KEY}`,
"Content-Type": "application/json",
},
body: JSON.stringify({
from: "Acme <hello@acme.com>",

return response.json();
}Common Pitfalls
