HTML-formatted email messages often provide plain-text version of their content (it is called alternative body). If alternative body is present in a message such message can be also viewed with older email clients that do not provide HTML support.

If you already have text file that you want to be used as alternative message body, use ImportAltBodyText method.


Code example:

' The code below is common for all examples in this topic

Dim Mailer

' Using Visual Basic to create object
Set Mailer = CreateObject("MailBee.SMTP")

' Using ASP to create object
' Set Mailer = Server.CreateObject("MailBee.SMTP")

Mailer.LicenseKey = "put your license key here"
Mailer.ServerName = "mail.server.com"

' The code below is specific to this sample

Mailer.Message.ToAddr = "bill@yoursite.com"
Mailer.Message.FromAddr = "joe@mysite.com"
Mailer.Message.Subject = "Hello"

' Import "email.htm" into HTML body
Mailer.Message.ImportBodyText "C:\docs\email.htm", True

' Import plain-text version of email into plain-text body
Mailer.Message.ImportAltBodyText "C:\docs\email.txt"

Mailer.Send

However, if plain-text version of the body is not available, MailBee can create it for you.

MakeAltBody method of the Message object converts value of BodyText property into plain form and places the result into AltBodyText property's value.


Code example:

' The code below is common for all examples in this topic

Dim Mailer
' Using Visual Basic to create object
Set Mailer = CreateObject("MailBee.SMTP")

' Using ASP to create object
' Set Mailer = Server.CreateObject("MailBee.SMTP")

Mailer.LicenseKey = "put your license key here"
Mailer.ServerName = "mail.server.com"

' The code below is specific to this sample

Mailer.Message.ToAddr = "bill@yoursite.com"
Mailer.Message.FromAddr = "joe@mysite.com"
Mailer.Message.Subject = "Hello"

' Import email.htm into HTML body
Mailer.Message.ImportBodyText "C:\docs\email.htm", True

' Generate alternative plain-text body from HTML body
Mailer.Message.MakeAltBody

Mailer.Send
Mailer.Disconnect

Finally, you can generate alternative body manually. Also, you can create alternative body using MakeAltBody method and then manually edit generated alternative body.

Alternative body content is actually stored in AltBodyText property. You can read or modify it the same way as BodyText property.

Note: Unlike BodyFormat, there is no AltBodyFormat property because alternative body is always plain-text.


Code example:

' The code below is common for all examples in this topic

Dim Mailer

' Using Visual Basic to create object
Set Mailer = CreateObject("MailBee.SMTP")

' Using ASP to create object
' Set Mailer = Server.CreateObject("MailBee.SMTP")

Mailer.LicenseKey = "put your license key here"
Mailer.ServerName = "mail.server.com"

' The code below is specific to this sample

Mailer.Message.ToAddr = "bill@yoursite.com"
Mailer.Message.FromAddr = "joe@mysite.com"
Mailer.Message.Subject = "Hello"

' Import email.htm into HTML body
Mailer.Message.ImportBodyText "C:\docs\email.htm", True

' Generate alternative plain-text code using
' another method (which allows to get plain-text
' version of any HTML source, not necessarily
' BodyText property value)
Mailer.Message.AltBodyText = _
  Mailer.Message.GetPlainFromHtml(Mailer.Message.BodyText)

Mailer.Send
Mailer.Disconnect
