Email address validation

Created by Daniel Beckett, Modified on Thu, 18 May, 2023 at 4:01 PM by Daniel Beckett

FLG has email address validation that runs when leads are created or updated. Leads are still accepted even if they have an invalid email address, however, you will not be able to contact the lead by email until the email address is corrected.

Why is email validation used?

Sending emails which bounce, whether due to spam traps or disposable email addresses negatively impacts our email sending reputation. This makes it harder for emails to reach the inbox.

By avoiding invalid email addresses it increases the likelihood of emails hitting your customers' inboxes and helps to improve the quality of your mailing lists.

For further information on email deliverability and spam please see this page.

What does the validation look like?

Lead view

On lead creation and update, invalid email addresses will be accepted into the system, however, when you view the lead, if the email address has failed the validation check, it will be marked with an Invalid badge as shown below:

Sending an email from a lead

On clicking Send, a validation check is carried out on the To, Cc and Bcc fields. If any email address in those fields is invalid, you will see an error message on screen telling you which email address is affected and giving you the opportunity to update it. The email will only be able to be sent once all email addresses are valid.

Bulk emails

Validation checks will be made on all editable email address fields throughout the bulk email wizard. Invalid email addresses will be shown in an error message for the field and will need to be corrected before you can proceed.

On sending, any email address which is invalid will not be attempted and a failure will be shown on the job output page as below:

Emails sent via workflows and lead actions

Emails will not be sent to invalid email addresses and an audit message will be added to the lead showing the email wasn’t sent due to the invalid email address (see 'Filters > View All Items' from the lead summary page).

Note: If an email is sent and fails due to an invalid email address, we will automatically mark the email address as Invalid and will not attempt to send to this email address again.
