Not able to get email when user submits the form

I have created contact form with react and connected it with mysql database hosted using RDS. i used django for building the database. before some days i was able to get email when i am submitting the form and the data was also been stored in the database but now when i am submitting the form i am not getting an email notification of submission but i can see the data in my database. i also tried to send test email from the console and it worked. when i changed the API from urls.py and then i submitted the form, i got the mail but when i did the submission again i did not get any mail.

this is my setting.py code

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': config('DB_NAME', default='myportfolio'),
        'USER': config('DB_USER', default='root'),
        'PASSWORD': config('DB_PASSWORD', default=''),
        'HOST': config('DB_HOST', default=''),
        'PORT': config('DB_PORT', default='3306'),
    }
}

# Email backend configuration
EMAIL_BACKEND = 'django.core.mail.backends.smtp.EmailBackend'
EMAIL_HOST = 'smtp.gmail.com'
EMAIL_PORT = 587
EMAIL_USE_TLS = True
EMAIL_HOST_USER = config('EMAIL_HOST_USER')
EMAIL_HOST_PASSWORD = config('EMAIL_HOST_PASSWORD')
