Hi  Community,

I want to send email after some delay(dynamic) means i have 
requirement that email should be trigger by delay and this is delay 
dynamic eg. for first email will trigger after 10 min when change stage 
and another may be some different time that we will manage in 
configuration.
So, how can i achieve this? Is there is any option odoo by which we 
can control datetime for email trigger by template or python function?
Now i try to achieve this by cron job but it not fulfill my requirement.
My python code is below:
partner = self.create_user_id.partner_id
if partner and customer_survey and auto_assign_survey and not self.response:
    survey_response = self.env['survey.user_input'].create({'survey_id': customer_survey,
                                                            'partner_id': partner.id,
                                                            'email': partner.email or None})
    survey_response.generate_public_url()
    survey_response.write({'helpdesk_ticket': self.id})
    self.write({'response': survey_response.id})
    if follow_up_template:
        follow_up_template.sudo().write({'email_to': partner.email})
        self.env['mail.template'].browse(follow_up_template.id).send_mail(self.id,
                                                                          force_send=False)
        if ir_cron_customize:
            self.env['ir.cron'].browse(ir_cron_customize.id).write(
                {'nextcall': datetime.datetime.now() + datetime.timedelta(minutes = 5)})

i am using odoo version-11
Thanks in advance.
