Convert HTML Web Page to Email and Send

See more MHT / HTML Email Examples

Converts an HTML page at a URL into an email with embedded images and sends it. Lua

local chilkat = require("chilkat")

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

local mailman = chilkat.MailMan.new()

-- The MHT component can be used to convert an HTML page
-- from a URL, file, or in-memory HTML into an email
-- with embedded images and style sheets.
local mht = chilkat.Mht.new()

local email = chilkat.Email.new()

-- There are two ways of embedding images in emails: with CIDs
-- and without.  When using CIDs, the IMG SRC attributes use
-- urls that begin with "cid:" and the corresponding image
-- embedded within the email includes a Content-ID header field.
-- When not using CIDs, the IMG SRC attribute can have a URL,
-- path, etc. and the corresponding image embedded within
-- the email has a matching Content-Location header field.

-- When testing with GMail, if CIDs are used the email will
-- be displayed with images blocked (by default) unless
-- the user allows them to be displayed.  Without CIDs,
-- the images are automatically displayed.

-- When testing with Eudora, Mozilla Thunderbird, and Outlook Express,
-- embedded images display correctly with our without CIDs.

-- When testing with Yahoo! Mail, embedded images display OK.
-- However, the Yahoo! Mail user has the option of blocking
-- images.  If this is turned on, the CID images will still
-- display correctly even though images are blocked.  Why?
-- It's because when viewing the email there is no external
-- HTTP request to fetch an image.  Therefore, a spammer
-- cannot get an indication that you've read the email.
-- However, if CIDs are not used, the images are blocked by
-- any Yahoo! Mail user that has image blocking turned on --
-- even though the images are embedded.

-- I haven't tested Hotmail yet...
-- Regardless, there is no perfect solution.  If CIDs are used,
-- GMail users may block your embedded images, if CIDs are not
-- used, Yahoo! Mail users may block your embedded images.

-- I recommend setting using CIDs.  This is what Mozilla Thunderbird
-- does by default, and it's the more clear an unambiguous way
-- to indicate that images are indeed embedded.
