I’m having trouble with my Mailgun implementation in Python. The code runs without throwing any exceptions, but the emails never reach my inbox. I’ve checked my spam folder too, but nothing shows up there either.
Here’s my current setup:
import requests
def dispatch_email():
response = requests.post(
"https://api.mailgun.net/v3/sandbox12ab3c4def5678gh9i012jk34l56m789.mailgun.org/messages",
auth=("api", "YOUR_API_KEY_HERE"),
data={
"from": "Test Sender <[email protected]>",
"to": ["[email protected]", "[email protected]"],
"subject": "Test Message",
"text": "This is a test email from Mailgun service!"
}
)
return response
The function executes successfully but no emails are delivered. Has anyone experienced similar issues with Mailgun’s API? What could be causing this silent failure?
Your sandbox domain is the problem. Mailgun sandbox domains only send to recipients you’ve manually authorized in the dashboard. I hit this same issue when I started testing with Mailgun. You need to add [email protected] and [email protected] to your authorized recipients list in the sandbox settings. Without authorization, Mailgun accepts the API call but doesn’t deliver anything. Either switch to a verified custom domain for production or add your test emails to the sandbox’s authorized list.
check the mailgun logs in the dashboard. it shows if the emails are sent or if there’s any issue. also, ensure ur api key is correct and the sender domain is verified. those sandbox domains need verified emails to work. gl!
I encountered a similar issue with Mailgun not delivering emails. It’s crucial to check the actual response from Mailgun’s API. Ensure to log response.status_code and response.text to capture any errors. Although your code runs fine, the API may return errors that you’re overlooking. Additionally, sandbox domains can be unpredictable even with verified recipients. Upgrading to a verified production domain significantly improved my delivery rates. Sandbox domains are mainly for initial testing and should not be relied upon for consistent delivery.
