About Open Rates for Broadcasts and Auto-Responses

They're basically useless as an absolute number, and only useful as a relative number, like a barometer. Meaning, you can test different subject lines and times of day for sending email, and see if your open rates are higher this time than they were before.

Here's why:

The way they're measured is by inserting a tiny invisible image into the body of the email. When the email client tries to show this image, it calls our server, which registers it as a sign that this email was opened.

However, many email programs, including Hotmail, Gmail, and MS Outlook, by default block all images in emails, and your reader has to actively choose to show images in order for the image to be shown so that we can register when the email was open. For this reason, only about half of all opens will be counted. That's the way all mailing list tools work.

What you can do with these numbers:

You can test different subject lines and different times of day for sending out your broadcasts and see if that changes the open rates upward or downward.

The sender name, the subject line and time of day, and perhaps the first few words of the body of the email (Gmail shows this on the overview page), as well as your relationship with the recipient, is what determines whether they'll open the mail. You can use the relative change in opening rates as an indication of how well these parameters worked.

What about clicks?

Clicks are 100% accurate. When someone clicks a link, we know for sure, because the click goes to Simplero first, then redirects to the URL you've chosen.

While it's true that we could count a click as an open (when someone clicks, we know they've opened the email, even if the hidden image was never requested). But then the presence or not of links in the email - or the popularity of certain links - would skew your open rates, and you would no longer be able to meaningfully compare open rates between broadcasts.

For this reason, you may experience click rates that are higher than your open rates. It is counter-intuitive, but there's a reason behind the madness.

And what about bounces and spam reports?

Bounces and spam reports are generally very reliable. When someone marks your email as spam in Hotmail or Gmail, we'll know for sure. When someone's email bounces, we know.

What if an email still doesn't go through to the recipient? 

Mail providers oftentimes delete an email that they think is spam, without even delivering it to the spam or junk mail folder. That's a huge frustration to someone trying to send a legitimate email that people want, but it's the way it is. We constantly work with providers in order to ensure that your email goes through, but we can't ensure it. That is ultimately up to the email providers such as Gmail, Hotmail, Yahoo, etc.

Therefore, you have to make sure you configure the domains that you send email from under the Settings in your Simplero. Email domains is a big help in ensuring your email will be delivered. See our guides on how to set up your Custom Domain.
