Delivery Delays to Gmail

In the past 48 hours Google has started delaying the delivery of some FeedMail notifications. This is currently affecting about 10% of messages to Gmail users. These notifications will be resent with a delay. We also speculate that some notifications will be marked as spam.

 Update: As of 2023-05-09 this appears to be resolved.

If You Are Affected

If you use Gmail you may be affected by this. Notifications may be delayed or marked as spam.

  • If your notifications are marked as spam you can create a filter to avoid this. Use "from:*@feedmail.org" as the rule and select "

More Details

The temporary rejection we are seeing from Google is in the form of:

transient error (421): 4.7.28 [165.22.236.104 15] Our system has detected an unusual rate of
4.7.28 unsolicited mail originating from your IP address. To protect our
4.7.28 users from spam, mail sent from your IP address has been temporarily
4.7.28 rate limited. Please visit
4.7.28  https://support.google.com/mail/?p=UnsolicitedRateLimitError to
4.7.28 review our Bulk Email Senders Guidelines.

FeedMail does not send unsolicited mail so this is a false positive. However it is possible that it was triggered by a user marking FeedMail notifications as spam instead of unsubscribing which lead Google to believe that these messages were unsolicited.

Our email sending rate to Google users has not changed notably in the past couple of weeks so it is surprising to see this error occur.

We have submitted a Sender Contact Form but it does not suggest that we should expect a response.

DNS Outage

From 2024-08-26 19:46 to 2024-08-27 11:21 UTC FeedMail had an outage. Until 2024-06-26 20:34 FeedMail was completely down. For the remainder of the outage most emails not sent. It is expected that no feed updates were lost during this outage. Updates would only be lost if they were only present on the feed within the 50min of total outage. Most feeds ensure that updates are present for days so this would not be an issue. Notifications have been delayed and should be sent by 2024-08-27 12:31. This may take longer if your mail provider applies limits and FeedMail needs to retry delivery at a later time. Update : All delayed notifications have been sent successfully. Timeline All times are in UTC . 2024-08-26 19:46 Start FeedMail goes down.   19:53 Detection Automated monitoring reported that feeds were not being checked. 20:34 The Database IP was hardcoded, restoring most functionality. 2024-08-27 11:21 Resolution FeedMail was switched external DNS. 11:24 Schedule of ...

Digests Now Respect Category Filters

Due to an oversight category filters did not apply to digests. This has been corrected and future digests will be filtered by your selected categories. If you do not want this filtering to occur please update your filters to "Ignore selected categories" and deselect all categories to inactivate the filter.

Digests are now Supported for Owner-Paid Feeds

Owner-paid feeds allow feed publishers to provide FeedMail to their subscribers at no cost. For example the FeedMail Blog is an owner-paid feed. Up until now digest subscriptions were not covered by owner-paid plans. Subscribers could select a digest but they would have to pay for the subscriptions themselves. Digests are now fully supported under owner-paid plans. For users: The owner-paid feeds in your digests no longer count towards the cost of the digest. For publishers: Users will now be able to receive your feed as a digest or included in one of their existing digests. You will be charged one credit for each digest issue containing items from your feed (no matter how many items from your feed are in that issue). Notably this cost will never be more than real-time subscriptions would be.
