LlamaNodes Premium | Email logic for notifying users their balance is low

[LlamaMB]

LlamaNodes Premium | Email logic and full feature for notifying users their balance is low:

Context: When a user’s Premium Balance is low, we want to email them with a remainder to top up - This is an opt-in feature.

Tech: We will capture the emails upon sign-up and then use SendGrid’s API to trigger and manage all the email notifications.

Steps: 1) Input: When a users signifies they want to receive email notification and input their email.

2) Collect email and verify it via verification email (to reduce spam issues) via PR #119 and PR #117 -Email collection is ask & completed in the account creation phase. -Email verification template (placeholder) can be found here: https://mc.sendgrid.com/design-library/your-designs/37bf6a74-924a-40db-9b32-fa7f4e39584d/preview

3) Output: When users balance is low | Less than $50.00 (?) -We have a built out email template (w/ graphics already completed).

Please let me know if you need any other information, thanks!

Use this to implement the Sendgrid API https://www.twilio.com/blog/send-emails-rust-sendgrid

The payload should look as follows, with the template-id being the one I created via the GUI

curl -X "POST" "https://api.sendgrid.com/v3/mail/send" \
     -H 'Authorization: Bearer <<YOUR_API_KEY>>' \
     -H 'Content-Type: application/json' \
     -d '{
