Real Email Validation = Real Email Opportunities

Incorrect, disposable, and bogus email addresses prevent you from reaching good customers. Add the email validator API to your webforms to verify email address and identify and correct troublesome addresses at the point of collection before the lead is submitted. Real email validation saves you money and time - allowing you to focus on real opportunities.

3 Great Reasons to an Validate Email Addresses

  • Boost Outbox Reputation

    You put in the effort to protect your sender reputation and to collect clean email addresses. Disposable and invalid email addresses 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 lead they are giving you permission to contact them. They expect to hear from you. When you are unable to reply due to accepting an invalid email or an address with a typo you have lost out on a potential relationship.

  • Improve ROI

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

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

Sending bulk email is a tricky business. According to this study the average email deliverability rate as of February 2020 was 79.6%. That means 20.4% remain undelivered or go to spam.

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