Email Verification API Functions
Email Format Checks
These APIs check if an email address is properly formatted. For example, they ensure it includes one '@' symbol and a valid domain structure.
Domain Status Checks
To confirm the domain is active, APIs use an SMTP handshake. This process checks if the domain’s mail server is set up to accept emails.
Advanced Email Validation
The API goes a step further by connecting directly to the mail server to verify the mailbox exists. It also evaluates potential risks, such as spam traps, disposable email addresses, or inbox-placement issues, helping you identify and filter out unreliable entries.
You can integrate these features into your website or backend systems to automate the process of cleaning your email lists.
Setting Up Email Verification APIs
Website Integration
Direct your form to Bounceless's verification endpoint to check email addresses as users enter them. This approach ensures better user experience and cleaner data.
Server-Side Setup
In addition to client-side checks, handle verification through your backend. Consult the Bounceless API documentation to set up authentication, manage requests, and automate tasks. You can also process existing lists in bulk using these APIs.
Bulk List Processing
For large email lists, bulk verification simplifies the cleanup process through the API. Here are some key steps:
- Remove duplicate entries
- Identify and eliminate invalid or poorly formatted addresses
- Confirm the validity of domains and mailboxes
- Detect and exclude spam traps
- Assess the likelihood of successful email delivery for each address
