Hey everyone, I’m running into some weird problems with email templates not going out properly. This is happening across several of my client accounts.
The issue shows up in two ways:
When I try to test send templates directly from the template editor
When templates get triggered through automation sequences
What’s really strange is that if I copy the exact same content (sender address, recipient, subject line, and message body) and send it manually from a contact record, everything works perfectly fine. The emails go through without any problems.
I’m using MailGun for email delivery. When I check my MailGun dashboard logs, these failed template emails don’t even show up there. But the manual emails I send appear in MailGun just fine and get delivered normally.
This makes me think there might be a platform-wide issue with how email templates are being processed right now.
Anyone else using MailGun integration having similar template sending issues? Would really appreciate if someone could test this on their end.
This sounds like a template processing issue, not MailGun itself. I had the exact same thing happen about six months ago - templates would just die before hitting the email provider. Turned out to be template variables that weren’t resolving properly when the automation triggered. The template looked perfect in the editor, but certain dynamic fields killed the whole email during processing. Try making a completely static test template with zero merge fields or variables and see if it sends. If it works, add the dynamic stuff back piece by piece until you find what’s breaking it. Also check if there were any recent platform updates that changed how template variables work.
Same issue here with Mailgun! Started about 2 weeks ago. Fixed it by going into each email template and hitting save again - didn’t change anything, just re-saved them. There’s definitely some sync problem between the platform and Mailgun that’s not updating right. Pain in the ass but the re-save trick fixed all my broken templates.
I encountered a similar situation with SendGrid a few weeks back where the email templates failed without any trace in the logs, which was incredibly frustrating. The manual sends went through fine since they bypassed the template process entirely. I recommend checking that your MailGun webhook URLs are still functioning correctly. In my case, regenerating the API keys and updating the webhook endpoints resolved the issue. It’s a good idea to review your integration settings, even if you haven’t made changes recently.
