If you have a spreadsheet full of potential prospects, you should make sure the emails won't bounce before you even think of emailing them. MailboxValidator can screen your email list to filter out those emails that no longer exists!

How It Works

  1. A new row is added to a SmartSheet spreadsheet
  2. Zapier sends the email address to MailboxValidator for validation
