You’ve spent so much time on your email marketing program – the last thing you need is an invalid or bad email address preventing your emails from reaching inboxes. Our Email Verification tool proactively protects your reputation and boosts delivery rates. Check each email address on your mailing list with three-step email validation. Our InboxReady suite of deliverability tools is a game-changer for email deliverability.
Improve your sender reputation and results with an email validator
Are your emails underperforming? Is your marketing team concerned with their email marketing campaigns’ click-through and open rates?
Your deliverability might be the issue.
Sending emails to bad addresses wastes your time and hurts your sender reputation – it may even land you on a blocklist, which sends your email campaigns straight to spam.
Nobody wants that.
When you ensure your message reaches valid emails with an email address validator, you’ll see a dramatic rise in open rates, click-throughs, and delivered emails. Mailgun’s Email Verification tool is straightforward to use and easy to integrate, so you can check and collect recipient email addresses. Our tool allows you to send marketing, ecommerce, and transactional messages with accuracy and integrity.
Mailgun goes beyond RFC rules
Mailgun’s Email Verification tool draws on billions of sent emails to perform a real-time, three-step email validation check for each email address. Upload a CSV file of your email list or use our Email Verifications API:
We check email accounts against the mailbox provider. RFC has formal rules for email addresses, but in the real world, email providers sometimes accept addresses that aren’t RFC-valid and reject addresses that are. Mailgun built its validator based on both real-world data and RFC specifications to provide more accurate email validation.
Mailgun’s bulk email verifier also factors in custom inbox service provider’s (ISP) grammar against Gmail, Hotmail, Yahoo Mail, Outlook, and more. All major ISPs have custom grammar and syntax rules, which affects email validity. The tool updates grammar checks after discovering ISPs’ new grammar rules.
Mailgun’s email checker keeps your sender reputation flawless
A bad sender reputation leads to 75% of all email delivery problems.
With Mailgun, you’ll never have to worry about your sender reputation or deliverability. Our Email Verifications ensure:
Your organization gains a strong sender score with top ISPs, so your IP addresses and domain names have a positive reputation. Plus, you’ll be able to easily stay compliant with data privacy and cybersecurity laws like GDPR and CAN-SPAM.
Your web forms catch errors and bad addresses before they cause a delivery problem. When you sign up, Mailgun’s API-driven email verification service will clean your email list and identify bad emails.
Hard bounces directly impact your deliverability. Removing bad email addresses ensures your bounce rate decreases thanks to removing spelling mistakes, temporary addresses, and disposable emails.
Don’t fall into a spam trap: Mailgun’s Email Verifications tool has you covered
Mailgun validates more than 200 million email addresses each month. Our intelligent Email Verifications API includes the following useful features:
Mailbox Verification: Mailgun checks whether a mailbox exists for supported mailbox providers. Plus, our service detects typos and catch-all addresses.
Role-Based Address Check: For all validation requests, Mailgun designates whether an email address is a “role-based address” like admin@ or sales@. These are often distribution lists that result in a high spam complaint rate and are best kept off your mailing list.
Disposable Email Address Detection: Disposable mailboxes are commonly used to commit fraud. Mailgun’s verification process detects when email addresses are on known disposable mailbox providers. Then, you can take action based on your risk assessments.
Reporting Dashboard: In Mailgun’s Control panel, it’s easy to track the validation API by the day (and even the hour). Mailgun provides specific information on valid and invalid email addresses along with the types of API calls we performed.
Rate Limiting of Validation API Key: Use rate limits on the validation API key to manage costs and prevent abuse.

How can I verify an email address without sending an email?
Here are three ways to validate email addresses without sending emails:
Ping the originating email server to access MX records, which tell you beyond a doubt whether or not this email address is valid and in use
Use Domain Name Service (DNS) lookup to verify a domain’s authenticity
Use an email validator, like Mailgun’s Email Verification tool
What’s an email validator?
An email validator, or an email verification tool, is a software tool that checks the validity of an email address based on whether or not it’s deliverable. In other words, can the email service provider place an email in your subscriber’s inbox? Validators check if the email syntax is correct, if the address can receive emails, and if it exists.
What’s a valid email?
A valid email is an email address able to receive messages. For instance, it’s composed with the correct syntax, it’s not a role-based email, its domain can receive messages, and it isn’t a high-risk, spammy email address.
How can I perform email validations?
You can validate emails at several points in your process. For example, you can implement regular expressions (RegEx) in your sign-up forms and pop-up web forms to collect email addresses. However, this doesn’t catch everything. Performing regular email validations to maintain email list hygiene is essential. An email verification tool helps make list verification part of your email process.
