[Ask IH] Do you use TempEmail or Disposable Email for testing out products or services?

Hi all!
As a product developer, I used temp-email.org for testing our Modules like

• Registeration Forms
• Email Templates

And also for testing out other products and services.

I am currently working on simple web extension to solve my problem which I feel like simply the workflow.

Looking for some thoughts on how other developer do

• If you are using disposable email services, can you please share the service name and some benifits of using it?
• Are you using web app or web extension?

Thanks in advance :)
