3 Great Reasons to Validate Email Addresses

Boost Outbox Reputation

You try to protect your sender’s reputation and collect clean email addresses. An Invalid or disposable email address can put that effort at risk by negatively influencing your reputation and endangering your link with valid email addresses. Check email validity before sending and preserve your sender reputation.

Strengthen User Experience

When a potential customer fills out your contact form or leads, they permit you to contact them. They expect to hear from you. When you cannot reply due to accepting an invalid email or an address with a typo, you have lost out on a potential relationship.

Improve ROI

Delivering your message to a valid email inbox increases engagement, improves sender reputation with email service providers, and leads to more conversions.

Email Validation Features

Email Syntax Validation

Check email addresses against universal formatting standards, including an @, a domain name, a period or full stop for our European friends (.), and a top-level domain (TLD) extension.

Proprietary AI Resource Check

Once we are sure we are dealing with an email address that is real, we apply some proprietary AI to test the integrity of the address.

Spam Trap and Honeypot ID

Detects email addresses of known spam traps and honey pots

Catch-All Identification

Detects domains that accept all emails, including fake emails

SMTP Check

Pings the email server to confirm the actual email address is valid without sending an email to the address owner

DNS and MX Records check

Test email addresses to see if they are associated with a valid domain and mail exchanger (MX record)

What is the point of sending an email that will never be received?

Sending a bulk email campaign is a tricky business. According to this study, the average email deliverability rate as of January 2023 was 81%. That means 19% remain undelivered or go to spam.

Email address verification improves the quality of your list and increases contact engagement.
