I have written a trigger, But it send Duplicate mail

[shuvo955]

`trigger ContractConversion on Contract (before update) {
for(Contract con : trigger.new) {
if(con.Status == '03 - Email to Customer') {
sendEnvelope.sendEnvelopeMethod(con.accountId,con.ContractNumber);

    }
}

}

public class sendEnvelope {

@future(callout=true)
//add comments about source
public static void sendEnvelopeMethod(Id accountId,string ContractNumber) {

	Final String templateGuid = '7635114e-743a-418f-ba6a-1d95a9d51b89';
 	//TemplateId contains the DocuSign Id of the DocuSign Template
	Final dfsle.UUID TemplateId = dfsle.UUID.parse(templateGuid);

	Account account = [SELECT Id FROM Account WHERE Id = :accountId
		LIMIT 1
	];

	// Create an empty envelope with Account Id as the source Id
	dfsle.Envelope envelope = dfsle.EnvelopeService.getEmptyEnvelope(
    	new dfsle.Entity(account.Id));
    
	
	//Find your contact to add
	Contact Contact = [SELECT AccountId, Name, Email FROM Contact
    	WHERE accountId = :accountId
    	LIMIT 1
	];
    
	//use the Recipient.fromSource method to create the Recipient
	dfsle.Recipient Recipient = dfsle.Recipient.fromSource(
    	Contact.Name, // Recipient name
    	Contact.Email, // Recipient email
    	null, //Optional phone number
    	'Customer', //Role Name. Specify the exact role name from template
    	//source object for the Recipient - Account
    	new dfsle.Entity(Contact.Id));
  

	

	//add Recipient to the Envelope
	envelope = envelope.withRecipients (
		new List<dfsle.Recipient> { Recipient });

	//create a new document for the Envelope
	dfsle.Document myDocument = dfsle.Document.fromTemplate(
	TemplateId, // templateId in dfsle.UUID format
	'E-Signature Email Template Contract'); // name of the template

	//add document to the Envelope
	envelope = envelope.withDocuments(
    	new List<dfsle.Document> { myDocument });
    // Send the envelope. 
	envelope = dfsle.EnvelopeService.sendEnvelope(
    	envelope, // The envelope to send
    	true); // Send now parameter not actually part of this method.
}

}

Have you tried calling the sendEnvelopeMethod outside of the trigger to see if it sends duplicate emails? If it does not, then somehow your trigger condition is triggering twice causing it to call the method twice. There is nothing functionally wrong with your sendEnvelopeMethod

I called the sendEnvelopeMethod from anonymous window it don't send duplicate mail. The trigger was being called twice. Thank you for your Help.
