[SalesForce] Email body is showing empty for some emails in email service handler

I have developed an email service handler in which I am noticing some some of them showing null in the plainTextBody field although there is a body present. Below is my sample code

global Messaging.InboundEmailResult handleInboundEmail(Messaging.InboundEmail email, Messaging.InboundEnvelope envelope) {
    Messaging.InboundEmailResult result = new Messaging.InboundEmailresult();

    try{            
       System.debug('from email address = '+email.fromAddress);
        System.debug('email subject = '+email.subject);
        System.debug('plainTextBody = '+email.plainTextBody); //this is showing blank in logs

The forwarding inbox has a copy of the email forwarded to the email handler address and I see the body is present in the email. Initially I thought it was due to HTML content in the email but I tried a couple of emails with HTML content and they seem to show the body fine(with html markup as text).

Could it be because the email was encrypted by the sender?

This code works if plainTextBody is blank, but htmlBody is not. There is a regex express to strip all html tags from the html body. The result may not be pretty, but the text should survive.

        String plainText = '';
    if (string.isNotBlank(email.plainTextBody)) {
        try {
              plainText = email.plainTextBody.substring(0, email.plainTextBody.indexOf('<stop>'));
        }
        catch (System.StringException e) {
             plainText = email.plainTextBody;
        }          
    } 
    else if (string.isNotBlank(email.htmlBody)) {
            // Process html body only if plain text body is blank      
        try {
            plainText = email.htmlBody.substring(0, email.htmlBody.indexOf('<stop>'));
        }
        catch (System.StringException e) {
             plainText = email.htmlBody;
        }
            // Strip all html tags from html body
        Pattern htmlPattern = Pattern.compile('</?[a-z][a-z0-9]*[^<>]*>'); 
        plainText = htmlPattern.matcher(plainText).replaceAll('');                     
    }

The error says you are trying to assign a String value (email.HtmlBody) to a Blob type field/variable (attachment.Body).

You can convert the String into a Blob and then assign it.

attachment.Body = Blob.valueOf(email.HtmlBody);

you can follow the examples in this developer force reference and create a note from the email text body

Note note = new Note();    
note.Title = email.fromName + ' (' + DateTime.now() + ')';
note.Body = email.plainTextBody;
note.ParentId = account.Id;
insert note;

[SalesForce] Email Body Text capture in Email Service

You will need to determine if the inbound email has a plain text body. If it doesn't then you need to convert the html to plain text.

string bodyText;
if (string.isEmpty(email.plainTextBody)
   bodyText = HtmlToText(email.htmlBody);
else
   bodyText = email.plainTextBody;

public static string HtmlToText(string html){
   //replace all <BR> tags with \n to support new lines
   string result = html.replaceAll('<br/>', '\n');
   result = result.replaceAll('<br />', '\n');

   //all HTML/XML tags
   string HtmlPattern = '<.*?>';

   Matcher match =  Pattern.compile(HtmlPattern).matcher(result);

   //remove the tags and return string     
   return match.replaceAll('');
}

Next, use a Matcher to search for 'Name:' and 'Email Address:'. These are two possible regular expressions that will return a line of text that starts with 'Name:' and 'Email Address:'

(?m)(?i)^name:.*

(?m)(?i)^email address:.*

These are multiline (?m) case-insensitive (?i) patterns that will match lines starting with Name: and Email Address:

Once you have the name and email address lines you can parse again to get the values you need to update the Account or Contact object.

The regular expressions above are based on my limited knowledge of what the actually email looks like. Be sure to test thoroughly in your unit test.
