Verifying valid email addresses ensures that your email campaigns reach their intended recipients. Without recipient validation, your emails may end up in receivers' spam folders. You can verify email validity in various ways:
You can evaluate the local and domain parts of each email to verify that the syntax is valid. The local part of the address may contain alphanumeric characters, printable characters, and a dot, while the domain may contain alphanumeric characters and a hyphen.
A message won't send if the recipient's email address includes any typos. Scan your email list to pinpoint common typographical errors.
Disposable emails are temporary addresses that are only valid for a designated amount of time. Look out for email addresses generated by services like Mailinator and Nada to eliminate disposable emails.
Domain Name System (DNS) lookups allow you to request a DNS record from the DNS server. You can use a DNS lookup to generate a mail exchange (MX) record, which identifies a domain name email server and enables you to choose one with the highest priority.
After performing a DNS lookup, you can connect to the Simple Mail Transfer Protocol (SMTP) server to query whether a recipient address exists. A server response of "250 OK" indicates that the address is valid, while negative responses indicate that it does not exist.
You can verify valid email addresses by sending a test email and observing whether it bounces or delivers. However, this process can be tedious and time-consuming.
