Title: Rate limits? Last modified: August 24, 2016 --- # Rate limits? * [bfinleyui](https://wordpress.org/support/users/bfinleyui/) * (@bfinleyui) * [11 years, 2 months ago](https://wordpress.org/support/topic/rate-limits/) * So I’m having some weird behavior. My site, using Paid Memberships Pro, sends an email to the admins, and the user, when a new person signs up. But the emails are arriving hours apart. I’m not sure about the specific API (if any) that postman- smtp is running, but I’m wondering if there’s some strange rate limit in effect? Has anyone experienced this, having issues sending two messages in the same script to different addresses? * They show up in the ‘sent mail’ area of my gmail account for which I’ve gone through the oAuth process, but don’t arrive for about an hour. Which for “click here to confirm your email” type messages is pretty not-ok. * Thoughts? * [https://wordpress.org/plugins/postman-smtp/](https://wordpress.org/plugins/postman-smtp/) Viewing 6 replies - 1 through 6 (of 6 total) * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [11 years, 2 months ago](https://wordpress.org/support/topic/rate-limits/#post-5989320) * If they are in the Sent box in Gmail, that means Google has them and is in charge of delivery. The delay occurs then, after Postman sends the Gmail and before the user receives it. * I can’t imagine why Google would delay sending an email, but it’s possible, if they are having technical problems. It’s not something that should be ongoing. * Yes there are sending limits for [Gmail](https://support.google.com/mail/answer/22839?hl=en) and [Google Apps mail](https://support.google.com/a/answer/166852?hl=en). * Are you sending FROM a Gmail address TO a Gmail address? Are you using a custom domain managed by Google Apps? * Thread Starter [bfinleyui](https://wordpress.org/support/users/bfinleyui/) * (@bfinleyui) * [11 years, 2 months ago](https://wordpress.org/support/topic/rate-limits/#post-5989324) * From a regular gmail address to another regular gmail address. The wordpress is just hosted on an amazon ec2 instance. * The delay also seemed to affect emails sent from gmail to non-gmail addresses. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [11 years, 2 months ago](https://wordpress.org/support/topic/rate-limits/#post-5989326) * Inspect the headers of the delayed email and see if there are SPF, DKIM, Spam or Phishing warnings. For Gmail -> Gmail, there shouldn’t be. * Thread Starter [bfinleyui](https://wordpress.org/support/users/bfinleyui/) * (@bfinleyui) * [11 years, 2 months ago](https://wordpress.org/support/topic/rate-limits/#post-5989328) * No errors there. Here’s the full headers of a delayed e-mail, no warnings, but you can see that the X-Received header near the bottom has a time of 10:28 PDT, but it doesn’t show up as being received until 12:18. * (I’ve changed the names of my servers and addresses, so there shouldn’t be any real identifiable information here) * ``` Delivered-To: to_address@gmail.com Received: by 10.36.51.146 with SMTP id k140csp4076633itk; Tue, 7 Apr 2015 12:18:20 -0700 (PDT) X-Received: by 10.140.107.72 with SMTP id g66mr24610220qgf.70.1428434300170; Tue, 07 Apr 2015 12:18:20 -0700 (PDT) Return-Path: Received: from mail-qk0-x241.google.com (mail-qk0-x241.google.com.

The first one came through immediately, the second took about an hour and a half. * Plugin Author [Jason Hendriks](https://wordpress.org/support/users/jasonhendriks/) * (@jasonhendriks) * [11 years, 2 months ago](https://wordpress.org/support/topic/rate-limits/#post-5989420) * Ya, you can see that Google held on it to it for two hours. No idea why. Did this happen before you installed this plugin? What if you send from a different Gmail account? Maybe this one has been flagged for something.
