Hi

In my case I needed to send an automatic instant email to all users who create a new account. In my Server Action I have my python code:

mail_template_id = 38
email_template = env['mail.template'].browse(mail_template_id)
email_template.send_mail(record.id, force_send = True)

I hope you find it useful.

i checked this links before i ask my question but i still canot do it :(
