Segna can automatically validate emails and drop rows with invalid emails. When building a pipeline, specify the fields containing emails and invalid emails will be considered along with duplicate and missing values. Alternatively, email validation can be specified as a row dropping method using our API.
Segna's email validation goes beyond checking the format of the email for correctness and makes requests to DNS servers to validate that the domain exists. For example an email
[email protected] may seem valid in format but domain checking will reveal this email address to be invalid.
DNS servers can be slow to respond to requests. This means that you may notice jobs taking a long time to run when a large number of rows (tens of thousands) with many different domains are present.
It is not possible to validate that the actual address is valid beyond checking the format and the domain. I.e.
[email protected]will be considered a valid email but may actually not be.
