        Lead__c LeadList=[Select Name,Email__c,Address__c,Contact_Phone__c,Company_Name__c,Status__c from lead__c where id=:LeadID];
        
            String ContactName=LeadList.Name;
            List<String> Splitname=ContactName.split(' ');
            System.debug('First Name'+Splitname[0]);
            system.debug('Last Name'+Splitname[1]);
            JSONGenerator gen = JSON.createGenerator(true);

Hi Saniya, 

Try below code and let me know 
  
global class LeadIntegrationMailChimp {

    Public static MailChimpSetting__c mailchimpsetting = MailChimpSetting__c.getInstance();
    @future(callout=true)
    
    public static void sendInfo(string LeadID)
    {
		Lead__c LeadList=[Select Name,Email__c,Address__c,Contact_Phone__c,Company_Name__c,Status__c from lead__c where id=:LeadID];
        
            String ContactName=LeadList.Name;
            List<String> Splitname=ContactName.split(' ');
            System.debug('First Name'+Splitname[0]);
            system.debug('Last Name'+Splitname[1]);
            JSONGenerator gen = JSON.createGenerator(true);
            gen.writeStartObject();
         /* String ContactName=LeadList.Name;
            gen.writeStringField('FName',Splitname[0]);
            gen.writeStringField('LName',Splitname[1]);
            gen.writeStringField('Address',leadList.Address__c);
            gen.writeStringField('Phone Number',leadList.Contact_Phone__c);
            gen.writeStringField('Business Name',leadList.Company_Name__c);
            gen.writeStringField('status',leadList.Status__c);
           */ 
            gen.writeStringField('email_address', leadList.Email__c);
      
            gen.writeStringField('status',leadList.Status__c);
            gen.writeEndObject();   
            String jsonS = gen.getAsString();
        
            System.debug('Jjson string'+jsonS);
			
		String apiKey = mailchimpsetting.Api_Key__c;
		Blob authValue = Blob.valueOf('user:' + apiKey);
		String authorizationHeader = 'Basic ' + EncodingUtil.base64Encode(authValue);
		
		// Determine data center and construct the path.

		req.setHeader('Authorization', authorizationHeader);
		req.setEndpoint( url );
		req.setTimeout(120000);
		req.setBody(jsonS); 
		
		Http http = new Http();
		//Execute web service call here       
		HTTPResponse res = http.send(req);    
		
		//Helpful debug messages
		System.debug(res.getBody());
		//System.debug('STATUS:'+res.getStatus());
