There are two distinct ways to verify the legitimacy of email addresses: Bulk email validation and Real-time email validation.

Real-time email validation identifies invalid email addresses at the time of sign-up on a website or landing page/ forms, whereas Bulk email validation validates numerous email addresses by uploading files in various formats such as CSV, TXT, and so on. Single email validation is appropriate for a small number of email validations; however, Bulk email validation is more efficient and cost-effective for confirming a large number of email addresses at once.
The main distinctions between the two are as follows:

Pricing:

Real-time Email Validation: Real-time validation can be included with other services, such as email sign-up forms, or it can be given for free.
Bulk Email Validation: The cost of bulk validation services frequently depends on the quantity of checks or the number of email addresses in your list. This could prove to be more economical when checking large lists.

Validation Range:

Real-time Email Validation: Using this technique, one email address is verified at a time. When you have a very limited number of addresses to verify or when you wish to confirm the legitimacy of a single email address that you have received, this method is usually employed.
Bulk Email validation: Bulk email validation, however, is made to process a lot of email addresses at once. It is appropriate when you have a large email database and wish to check several addresses at once to clean and optimize your email list.

Timing:

Real-time Email Validation: If you need to verify a lot of email addresses, it might take a while to verify in a single email validation.
Bulk Email Validation: Bulk email validation can process more emails at once, deliver results more quickly, and save time.

Process:

Real-time Email Validation: This feature is frequently included in online forms and websites to validate email addresses as users enter them. Immediate feedback can assist users in correcting mistakes and reducing typos.
Bulk Email Validation: Generally, bulk email validation is done in a semi-automated manner. A list that you upload is processed by the verification service. Following verification, you will receive a report with information.
