You can try the following:

template = self.env['email.template'].search[('name', '=', 'Name of email template'))
if not template:
    raise exceptions.Warning("Email template not found!")
template.send_mail(record.id, force_send=True)

Setting force_send to True will immediately send the email, whereas if you set force_send to False, the mail will push to the mail queue and be sent later (30min intervals) by a cron job.
