What it does:
Checks whether the email address looks valid and belongs to a valid email domain (like gmail.com
, outlook.com
, or your company’s domain).
What it doesn't do:
Does not confirm whether the specific email address is in use or can actually receive mail.
Use case:
Ideal for quickly confirming that the domain part of an email address is real and correctly formatted before accepting it into your system.
What it does:
Attempts to confirm whether the email address can actually receive emails right now. This includes checking for issues like:
Full mailbox
Disabled mailbox
Mail server rejecting messages
What it doesn't do:
Does not guarantee the recipient will read or respond to the email—it only checks technical deliverability.
Use case:
Best for campaigns, onboarding, and scenarios where email delivery is critical.
What it does:
Checks if the phone number is formatted correctly and matches a valid number structure for the specified country code. Checks that the number exists on the network, but importantly it does not check whether or not the number is active and can receive calls or text messages!
What it doesn't do:
Does not verify that the number is currently in service or assigned to a real user.
Use case:
Useful for ensuring you're collecting properly formatted, dialable numbers before accepting them into your system.
