MailChimp used to send out a client's newsletters from RSS feed without issue. A few weeks ago, they started showing up a day later. After weeks of trying to get support to track down this bug, we finally got this response<p>"Thank you for your patience while my team looks at this. We were able to confirm that the best time range currently to space the blog posts is 10-12 hours before Mailchimp's sending time. There just isn't enough time between your posts and the feed to pull the new content.<p>As a best practice, I would plan your content releases a day in advance with this functionality in mind."<p>It started with 4 hours, now they are telling us 10-12 hours in advance? My client runs a news site and sends our daily news. It's not always possible to even publish content that far in advance. It's insane to me that this functionality was working fine, for years. That they have managed to break and instead of fixing are saying just publish an insane amount of time ahead of the newsletter being sent?<p>I'm not sure what it takes to get someone's attention at MailChimp to actually fix this. Read the RSS feed before sending the scheduled post. Like it used to. Otherwise, what newsletter providers would people recommend replacing MailChimp with?
