Sending to old email addresses and bad actors drive down your engagement, damage your sender reputation, and cost you money. Not only can Validations alert you to risky email addresses, but this feature also provides a breakdown of your audience’s engagement behavior based on their past 30 days of activity. You can even run a list preview for free and see aggregate results before deciding to validate the entire list. Access to Validations begins on the Foundation plan. Review the plan details and upgrade at any time ( https://app.mailgun.com/app/account/mailgun/upgrade?utm_campaign=mg_onboarding_free&utm_medium=email&utm_source=cio ) within your account.
