Emails getting caught in Gmail Spam? Find out why using...Gmail.

You know that sending your transactional email through Postmark is the best way to improve your delivery rates. But sometimes, even with the best of tools and intentions, your emails will end up in spam and you won’t know why.

The next time you’re working to troubleshoot why an email is going to your (or your customers’) spam filter in Gmail, you can click on the email itself and look right below the sender and recipient information for more information about why Google thinks that email is spam.

Gmail will mark messages that are sent to undisclosed recipients.
Gmail also marks when a message was marked as spam because it matches other messages it has filtered.
Gmail will also mark messages as spam from senders you've marked as spam in the past.

Even when you’re sending through Postmark, it’s a great idea to make sure that you are set up to periodically receive copies of your transactional emails, and take special notice when you make copy changes. If emails start going to spam, you can use this new Gmail feature to try to determine why.

Of course, if you’re ever stumped as to why an email sent with Postmark isn’t being delivered or is landing in the spam filter, Postmark’s expert support team is ready to help you diagnose the problem.
