Mailgun Send Email using MIME

See more Mailgun Examples

Send an email using MIME. This allows for the Chilkat email object to be used to construct the email. Then it can be sent using Mailgun. Lua

local chilkat = require("chilkat")

-- This example assumes the Chilkat API to have been previously unlocked.
-- See Global Unlock Sample for sample code.

-- We're going to create an email that contains an .zip attachment,
-- and also both plain-text and HTML alternative bodies.
-- The HTML body will include an image.

local email = chilkat.Email.new()

-- Adding attachments, HTML/plain-text bodies, etc can be done
-- in any order:

-- Add an attachment
local contentType = email:add_file_attachment("qa_data/hamlet.zip")
if not email.last_method_success then
    print(email.last_error_text)
    return
end

-- Add some headers:
email.subject = "This is a complex email"
-- Please change this email address before testing.
local success = email:add_to("Joe Example", "joe@example.com")
email.from = "Your Name <mailgun@YOUR_DOMAIN_NAME>"

-- Add a plain-text body:
email:add_plain_text_alternative_body("This is the plain-text body")

-- Add an image that will be embedded in the HTML body.
success = email:add_related_file2("qa_data/jpg/starfish.jpg", "starfish.jpg")
if not success then
    print(email.last_error_text)
    return
end

-- Add an HTML body:
local html = "<html><body><b>This is the HTML body</b><br><img src=\"starfish.jpg\"></body></html>"

email:add_html_alternative_body(html)

-- ------------------------------------------------------------------------
-- Send the above email using Mailgun

local http = chilkat.Http.new()

-- Implements the following CURL command:

http.login = "api"
http.password = "sending_api_key"-- Replace with your actual sending API key.

local req = chilkat.HttpRequest.new()
req.http_verb = "POST"
req.path = "/v3/YOUR_DOMAIN_NAME/messages.mime"
req.content_type = "multipart/form-data"

req:add_param("from", "Your Name <mailgun@YOUR_DOMAIN_NAME>")
req:add_param("to", "Joe Example <joe@example.com>")
req:add_string_for_upload2("message", "message.eml", email:get_mime(), "utf-8", "application/octet-stream")

local resp = chilkat.HttpResponse.new()
success = http:http_sreq("api.mailgun.net", 443, true, req, resp)
if not success then
    print(http.last_error_text)
    return
end

local sbResponseBody = chilkat.StringBuilder.new()
resp:get_body_sb(sbResponseBody)
local jResp = chilkat.JsonObject.new()
jResp:load_sb(sbResponseBody)
jResp.emit_compact = false

print("Response Body:")
print(jResp:emit())

local respStatusCode = resp.status_code
print("Response Status Code = " .. respStatusCode)
if respStatusCode >= 400 then
    print("Response Header:")
    print(resp.header)
    print("Failed.")
    return
end
