Resend Email

hey, I'm created an enquiries page for people to send an email to the enquiries email address, I want to send the email from the email address they provided to my enquiries account, is this possible? this is my nextjs API route which is using Resend,

import { env } from "@/env.mjs";
import { type ErrorResponse } from "resend";
import { z } from "zod";
import { resend } from "@/lib/resend";
import EnquiryEmail from "@/components/emails/enquiry";
import { contactSchema } from "@/lib/validations/contact";

export async function POST(req: Request) {
  const input = contactSchema.parse(await req.json());

  try {
    await resend.emails.send({
      from: input.email,
      to: env.EMAIL_FROM_ADDRESS,
      subject: `Enquiry from ${input.firstName} ${input.lastName}`,
      react: EnquiryEmail({
        firstName: input.firstName,
        lastName: input.lastName,
        email: input.email,
        phoneNumber: input.phoneNumber,
        addressLine1: input.addressLine1,
        cityOrTown: input.cityOrTown,
        postcode: input.postcode,
        enquiry: input.enquiry,
      }),
    });

    return new Response(null, { status: 200 });
  } catch (error) {
    console.error(error);

    if (error instanceof z.ZodError) {
      return new Response(error.message, { status: 422 });
    }

    const resendError = error as ErrorResponse;

    if (resendError?.error?.message) {
      return new Response(resendError.error.message, { status: 429 });
    }

    if (error instanceof Error) {
      return new Response(error.message, { status: 500 });
    }

    return new Response("Something went wrong", { status: 500 });
  }
}

import { env } from "@/env.mjs";
import { type ErrorResponse } from "resend";
import { z } from "zod";
import { resend } from "@/lib/resend";
import EnquiryEmail from "@/components/emails/enquiry";
import { contactSchema } from "@/lib/validations/contact";

export async function POST(req: Request) {
  const input = contactSchema.parse(await req.json());

  try {
    await resend.emails.send({
      from: input.email,
      to: env.EMAIL_FROM_ADDRESS,
      subject: `Enquiry from ${input.firstName} ${input.lastName}`,
      react: EnquiryEmail({
        firstName: input.firstName,
        lastName: input.lastName,
        email: input.email,
        phoneNumber: input.phoneNumber,
        addressLine1: input.addressLine1,
        cityOrTown: input.cityOrTown,
        postcode: input.postcode,
        enquiry: input.enquiry,
      }),
    });

    return new Response(null, { status: 200 });
  } catch (error) {
    console.error(error);

    if (error instanceof z.ZodError) {
      return new Response(error.message, { status: 422 });
    }

    const resendError = error as ErrorResponse;

    if (resendError?.error?.message) {
      return new Response(resendError.error.message, { status: 429 });
    }

    if (error instanceof Error) {
      return new Response(error.message, { status: 500 });
    }

    return new Response("Something went wrong", { status: 500 });
  }
}

or instead would I just email myself basically?

I would send from [email protected] with a reply_to param of their address. It looks like Resend supports this. https://resend.com/docs/api-reference/emails/send-email This represents the actual situation clearly: your server is sending this email, not their email provider, but replies should be addressed to their email address.

Start sending emails through the Resend Email API.

You could also send from [email protected], but apparently it's considered best practice to send transactional emails from an address that accepts incoming mail, even if you mostly don't read it

oh thanks, i read through the docs but for some reason didn’t find this page? maybe i’m blind 😬

Took me a second to find it as well. Lots of examples, but the actual API docs aren't obvious 😅
