Is this email format good for approving/rejecting approvals without mail script or images?

Hi Community,

I’ve customized an email notification in ServiceNow to allow approvers to take action (Approve/Reject) directly from the email, without using any mail scripts or images.

I want to confirm:
Is this a good and reliable way to implement Approve/Reject buttons in notifications?
Here’s the code I’m using:

Questions:

• Is this the best practice for email-based approvals?

• Are there any risks or limitations I should be aware of?

• Will this reliably work across most email clients and instances?

Appreciate your feedback!
