If you haven’t been living under a rock, you probably know that SendGrid released Transactional Templates recently. I’ve been using them for a while, specifically for my API demos. It makes it super simple for me to customize emails for a specific school or crowd on the fly without touching any code. With Transactional Templates I don’t ever touch my code.

Here is how my code looks like:

import sendgrid
import os

sg = sendgrid.SendGridClient(os.getenv('SG_USER'), os.getenv('SG_PWD'))
mail = sendgrid.Mail(subject='10', reply_to='hi@sgdemos.com', html='Happy Hacking!', text='Happy Hacking', from_email='yamil@sendgrid.com', from_name='Yamil @elbuo8')
mail.add_filter('templates', 'enable', 1)
mail.add_filter('templates', 'template_id', 'fd6ecf80-fc43-46da-80b0-f3e26777b514')

Now if I want to go to HackRU and give a demo, I don’t have to change anything in my code. I can go to the Templates interface and activate the template that I set up for HackRU.

When I send my email, it will look like this:

Now, next weekend I’ll probably head on over to hackNY, I just need to activate that template and I’m done.

If you notice, the only thing that matters is the ID of the template 🙂

Convenient right? Anyone can start using the Template Engine! If you have any issues or questions, feel free to poke me @elbuo8.
