Email addresses get added to many apps through signups, contact forms, lead-generation tools, subscriptions, and new account creation. If people give wrong or risky addresses, this is not good for a database. It can also make it tough to talk to people later. Real-time email check APIs help developers know if addresses are good as people type them in. This cuts down the need to clean things up by hand later.

What Developers Should Evaluate
Before you use a verification API, you have to think about more than if the answer is good or not. There are other things that matter, like these:
- API response speed
- How well it checks if something is real
- Finds throwaway and all-purpose emails
- Response statuses you can get
- Guide on how to connect
- Which computer languages it works with
- Pricing and how your credits are taken
- How they handle your privacy and data
The way the API handles results that are not clear is important. If there is an address that we do not know for sure, it should not be treated the same as an address that we are sure is wrong.
