Communications APIs.
A communications API handles the message layer around your product — checking that an address is real and deliverable before you send to it, drafting the copy, and standing up throwaway inboxes when you need to test the flow end to end.

SharpAPIVerifiedEmail Validation API: Check Domains and Block Disposable Emails
The Email Validation API checks whether an email address is worth accepting. It confirms the address is correctly formatted, that its domain is set up to receive email, and, by default, that it doesn't come from a disposable email service. You get back a single true or false. Use it on sign-up forms, contact forms, and newsletter subscriptions to stop typos and throwaway addresses before they reach your database, or run it over imported lead lists to remove addresses that would bounce. Set disposable_checks to false if you want to accept temporary addresses. The check confirms the domain can receive mail, but not that a specific mailbox exists. For a more detailed view of how likely an address is to receive your messages, use the Email Deliverability Score API. You can start on ApyHub's free tier with no card required.
