Dim email As New ChilkatEmail
Dim success As Long

email.Subject = "Sample AMP for Email"
email.From = "mary@example.com"
success = email.AddTo("Joe","joe@example.com")

' Create the following AMP for Email HTML

' <!doctype html>
' <html amp4email>
' <head>
'   <meta charset="utf-8">
'   <style amp4email-boilerplate>body{visibility:hidden}</style>
'   <script async src="https://cdn.ampproject.org/v0.js"></script>
' </head>
' <body>
' Hello, world.
' </body>
' </html>

Dim sbAmp4Html As New ChilkatStringBuilder
success = sbAmp4Html.Append("<!doctype html>")
success = sbAmp4Html.Append("<html amp4email>")
success = sbAmp4Html.Append("<head>")
success = sbAmp4Html.Append("<meta charset=""utf-8"">")
success = sbAmp4Html.Append("<style amp4email-boilerplate>body{visibility:hidden}</style>")
success = sbAmp4Html.Append("<script async src=""https://cdn.ampproject.org/v0.js""></script>")
success = sbAmp4Html.Append("</head>")
success = sbAmp4Html.Append("<body>")
success = sbAmp4Html.Append("Hello, world.")
success = sbAmp4Html.Append("</body>")
success = sbAmp4Html.Append("</html>")

' We want to build a multipart/alternative email, where the 1st alternative body
' is text/plain, the 2nd is text/x-amp-html, and the last is text/html.
' (Some email clients will only render the last MIME part, so we recommend placing the text/x-amp-html MIME part before the text/html MIME part.)

' First create a plain-text email body:
success = email.AddPlainTextAlternativeBody("Hello World in plain text!")

' Now add the text/x-amp-html.
email.SetTextBody sbAmp4Html.GetAsString(),"text/x-amp-html"

' Now add an HTML body..
success = email.AddHtmlAlternativeBody("<span>Hello World in HTML!</span>")

' See what we have:
Debug.Print email.GetMime()

' This is the result:
