Overview
Email Validation in Marketing Pro settings acts like a filter that will configure your outgoing marketing emails to protect your sending reputation. By using Email Validation, you can block marketing emails from going to email addresses that are not likely to be real, or which could cause your emails to be flagged as junk mail. You can also choose to set the risk levels at which this filtering is automatically implemented.

Things to know
New customer email addresses are automatically validated and assigned a risk level and risk category.
You won’t see the bad email addresses in the suppression email list, but they are included in your Sent emails list. For more on suppressed emails, see Manage the suppression list.
Risk level overview
You can set Marketing Pro to block sending to email addresses automatically at certain risk levels:
High: This is the recommended default risk level. All potentially invalid email addresses are suppressed and messages are not sent to them. Select High to keep your email open rates high.
Medium: Suppresses most potentially invalid email addresses, but does not suppress role-based email addresses such as emails sent to admins, managers, and more.
Low: The lowest level of automatic suppression. Low still suppresses undeliverable and risky email addresses, and email addresses that contain typos, but does not suppress other potentially risky email address types.
Set email validation preferences
Go to the top toolbar and click Settings
.From the side panel, go to Marketing Pro > Email Validation.
Select High (recommended), Medium, or Low.

Email validation risk categories
Email validation risk categories can differ according to the validation levels. Risk levels include:
Undeliverable: Emails sent to this address would likely result in a Hard Bounce because the User does not exist, lowering your open rates. The receiving email server may be temporarily unavailable, overloaded, or not there at all.
Risky: Emails sent to this address would likely be marked as Spam, lowering your open rates and harming your sending reputation. Risky email addresses have been found on one or more suppression lists, or are known spam traps.
Typo: An email address that contains a typo. Emails sent will likely result in a Hard Bounce, lowering your open rates. Typo email addresses were entered incorrectly during sign-up, often due to a mistake like gmil.com instead of gmail.com.
Accept-All: Emails sent to Accept-All addresses likely won’t be opened, lowering your open rate. Although Accept-All email addresses accept all incoming emails, they usually do not belong to an actual person or customer. Accept-All emails are often used by businesses to catch spam or malicious emails.
Disposable: Emails sent to this address likely won’t be opened, lowering your open rate. Disposable email addresses are usually created to sign up for a service and then discarded and are usually not checked again.
Role: This email addresses a role or group of different people. Emails sent to this address probably won’t be seen by the intended audience recipient, lowering your open rate and potentially being marked as spam.
Unknown: An email address with an unknown issue. Emails sent to unknown addresses are likely to result in a Hard Bounce, lowering your open rates. Email addresses with an unknown issue can’t be validated, usually because of a connection problem or an unresponsive email server.
