up to 50k Bulk Email Checker Service

Email verification is a crucial process that confirms the validity and deliverability of an email address: it is commonly used by businesses to ensure that the email addresses they collect on sign-up forms or use in their mailing lists are valid and capable of receiving messages, with the goal of reducing bounces and safeguarding their sender reputation with email service providers. Our proprietary email verification technology involves over 30 steps, including checks on email address syntax with support for internationalized (non-ASCII) addresses, verification of the domain and its DNS records (including MX records), detection of disposable email addresses, execution of diagnostic commands on SMTP mail exchangers and much more.

We employ AI to precisely monitor results on every step of the process and generate detailed email verification reports.

A bounce refers to an email that cannot be delivered successfully to the intended recipient; bounces occur for various reasons, and they are typically classified into soft bounces, which are temporary delivery issues (due to a full mailbox, for instance), and hard bounces, which are permanent delivery failures.

Our email checker aims to reduce bounce rates by identifying and removing invalid or non-functional email addresses from a mailing list before sending out email campaigns: minimizing bounces is important for maintaining a good sender reputation, as consistently sending emails to invalid addresses can negatively impact how email service providers view your sender status, potentially leading to emails being marked as spam or not delivered at all.

Sender reputation refers to the overall track record of an email sender's behavior, particularly in terms of sending practices and user engagement: a sender with a positive reputation is more likely to achieve successful email delivery to recipients' inboxes, while a poor reputation may lead to emails being flagged as spam or failing to reach the intended recipients.

When assessing sender reputation, email service providers (ESPs) consider various critical factors, including bounce rates, spam complaints, email volume, the implementation of proper authentication mechanisms (such as SPF, DKIM, and DMARC), and the quality of content.

Using our email tester allows to remove bounces and keep your mailing list clean, improving your sender reputation.
