Email checking is the process of reviewing an email address to identify problems that could prevent successful delivery . It can be used when collecting new addresses, reviewing an existing contact list, or preparing an email campaign.
What Does Email Checking Include?
The checks can range from a basic format review to more detailed checks of the address and its domain. Common checks include:
- Syntax: Checks whether the address follows a valid email format.
- Domain: Checks whether the domain exists and is set up to handle email.
- Mailbox: Looks for signals that the specific address can receive email.
- Disposable email : Identifies addresses linked to temporary email services.
- Catch-all : Identifies domains that accept email even when the individual mailbox cannot be confirmed.
When Should You Check an Email Address?
Checking email addresses is useful when adding new contacts, reviewing an older list, or preparing for a large email send. Running checks before sending can help identify addresses that could lead to failed deliveries and unnecessary bounces.
Email Checking vs. Email Verification
Email checking can refer to a basic review of an email address, such as checking its format or domain. Email verification goes further by using additional checks to determine whether the address is likely to accept email.
For example, checking name@example.com can confirm that the address follows the expected
format, while verification can also examine the domain, mail server, and other signals related to the
recipient mailbox.
