It comes with a free subscription of 12,000 emails.

Now let's see how to configure and send emails from SendGrid.
The following is the sample Python code that can be used to send emails from SendGrid. The code is very simple and self-explanatory. You just have to make sure that you are using the right API key:
# using SendGrid's Python Library - https://github.com/sendgrid/sendgrid-python
import sendgrid
sg = sendgrid.SendGridClient("YOUR_SENDGRID_API_KEY")
message = sendgrid.Mail()
message.add_to("[email protected]")
message.set_from("[email protected]")
message.set_subject("Sending with SendGrid is Fun")
message.set_html("and easy to do anywhere, even with Python")
sg.send(message)
The preceding code is used to configure the SendGrid client, recipient, sender, subject, and the message in the email body.
