Gmail Sending Limits

How to Not Be Labeled a Spammer (updated 08/11/2018)

Recently I noticed that a client’s web site form was not delivering the emails to the Google Ap’s email address the form contents go to. This is a quote form for potential customers to inquire about shipping costs, etc.

After investigating it turns out that Google/Gmail had decided that my client had “possibly” sent spam emails and BLOCKED HIS EMAILS from reaching Gmail users. That’s almost everyone, right?!

Here’s what happened. After looking at my client’s email logs (pulled by the hosting service) it was obvious that bulk mail that exceeded Gmail’s permitted limits had been sent by my client. Here is an example of one of the logs with identifying information removed.

“Our system has detected an unusual rate of…… unsolicited mail originating from your IP address. To protect our……… users from spam, mail sent from your IP address has been temporarily……… rate limited. Please visit http://www.google.com/mail/help/bulk_mail.html to review our Bulk Email Senders Guidelines. “

What this means is that your email does not get delivered to other Gmail users, or Outlook or Postini or SpamAssasin now think your email is potential spam. It can even add a subject to your emails that read “Spam-Low” or med or high (in this case Low) to emails received by your contacts.

To quote Google:

“To help prevent spam and keep accounts safe, Gmail limits the number of emails you can send or get per day, and the number of people you can add as recipients.

How many emails can you send in one day?

Follow Gmail’s guidelines for sending email and bulk mail. They provide you with options and rules. Finding that information in Gmail can be daunting so I’ve included this link to help you educate yourself on the email sending limits and rules for Gmail.
