Spam email addresses checker is still one of the most popular ways to reach potential customers and clients. However, just pressing the send button is not enough to guarantee that your messages land in your recipients’ inboxes and not in spam or junk folders. It is crucial to verify each address before sending to prevent bad email addresses (fake, invalid, non-existent) from hurting your email deliverability and reputation.

A reliable and accurate email validation tool can help you avoid wasting time and money on a marketing campaign that ends up in your audience’s junk folder. An email verification service scans the syntax of an email address and confirms that it is a valid inbox with the mail server. It also checks for spam and non-existent email accounts, disposable email addresses and more.

In addition to checking for the validity of an email, email verification services check DKIM signatures and verify the email domain configuration. The latter is important because it determines whether an email is hosted on a legitimate email provider. If an email domain is hosted on a spam-free or legitimate network, it increases the email deliverability score.

Additionally, email verification services analyze spam, fraud and abuse complaints in the DNS records of the email domain. If there are too many spam, fraud or abuse complaints, your email might be blocked by ISPs. Email verifiers also look for role based email addresses, such as sales@ or info@ that are shared with different teams.
