Hi,

One solution you could implement is as follows:

- Create a visualforce page which will be rendered in PDF(Using renderAs="PDF" attribute), design this page in the recipt format and include all the neccessary data you want to put in the receipt or document for a particular donation record.
- Write an after insert trigger on the object(which you are using to store donation).
- From the trigger create instance of the visualforce page (which will be rendered as PDF document) and send this document as an atachment to the appropriate email address:

Visualfoprce page:

<apex:page standardController="YourObject" extensions="YourController" renderAs="PDF">
    <!--  Put the data for the receipt or document in this page, the content rendered in this page will be sent as an attachment with the email -->
</apex:page>

Trigger

Trigger DonationTrigger(After insert){

//get the donation record
//call the method to send the document as an attachment

}

Method to send email:

public void sendEmail(){
    PageReference pdfDocPage = Page.YourPageName;
    // Add record id in parameters(to be used by standardController)
    pdfDocPage.getParameters().put('id',Your_Object_Id);
 
    // returns the output of the page as a PDF
    // Remember that getContent() method is not supported in test context
    Blob pdfDocPageBody = pdfDocPage.getContent();
    
    // Create attachment record    
    Messaging.EmailFileAttachment attach = new Messaging.EmailFileAttachment();
    attach.setContentType('application/pdf');
    attach.setFileName('FileName.pdf');    
    attach.Body = body;
 
    Messaging.SingleEmailMessage mail = new Messaging.SingleEmailMessage();
    mail.setToAddresses(new String[] { mailTo });
    mail.setSubject("Email Subject");
    mail.setPlainTextBody("Email body");
    mail.setFileAttachments(new Messaging.EmailFileAttachment[] { attach });
 
    // Send the email
    Messaging.sendEmail(new Messaging.SingleEmailMessage[] { mail });
}
