How to Send Emails with Go

Add transactional email sending to your Go application using AISend's REST API. Simple HTTP calls, no SDK required.

1. Send with net/http

Use Go's standard library to call the AISend API:

package main

import (
    "bytes"
    "encoding/json"
    "net/http"
)

type EmailRequest struct {
    From    string `json:"from"`
    To      string `json:"to"`
    Subject string `json:"subject"`
    HTML    string `json:"html"`
}

func sendEmail() error {
    payload := EmailRequest{
        From:    "hello@yourdomain.com",
        To:      "user@example.com",
        Subject: "Hello from Go",
        HTML:    "<p>Sent with AISend from Go.</p>",
    }

    body, _ := json.Marshal(payload)

    req, _ := http.NewRequest("POST", "https://api.aisend.app/v1/emails", bytes.NewBuffer(body))
    req.Header.Set("Authorization", "Bearer as_your_api_key")
    req.Header.Set("Content-Type", "application/json")

    resp, err := http.DefaultClient.Do(req)
    if err != nil {
        return err
    }
    defer resp.Body.Close()

    return nil
}
