Help! My Laravel app won’t send emails through Mailgun
I’m stuck trying to get my Laravel app to send emails via Mailgun. I’ve gone through all the steps:
Set up Mailgun account and verified DNS
Updated config/mail.php with Mailgun driver
Added Mailgun settings to config/services.php
Put Mailgun credentials in .env file
Everything looks good but no emails are actually being sent. When I check the Guzzle logs, I see a 200 success response. I even tried a direct cURL request to the Mailgun API which returns “Mailgun Magnificent API”.
So it seems like the requests are going through, but no emails are arriving. I’m totally stumped! Any ideas what could be wrong with my setup or what I might be missing? Thanks for any help!
Have you checked your Mailgun logs? Sometimes emails can appear to send successfully but get caught in spam filters or encounter delivery issues. I’d recommend reviewing the Mailgun dashboard for any failed deliveries or bounces.
Another thing to consider is your sending domain configuration. Make sure you’ve properly set up and verified your sending domain in Mailgun, including all required DNS records (SPF, DKIM, DMARC).
If those look good, try sending a test email to a different email provider (e.g. Gmail if you’ve been testing with Outlook). Different providers have varying spam detection algorithms.
Lastly, double-check your .env file to ensure there are no typos in your Mailgun credentials. Even a small error there could cause silent failures.
hey mate, have u tried checkin ur spam folder? sometimes emails end up there. also, make sure ur using the correct mailgun region (EU or US) in ur config. i once spent hours debugging cuz i had the wrong region lol. if nothin else works, try sendin a test email directly from the mailgun dashboard to see if its a laravel issue or mailgun problem.
I’ve been down this rabbit hole before, and it’s frustrating when everything looks right but emails aren’t going through. One thing that saved me was enabling debug mode for the mail driver. Add ‘MAIL_DEBUG=true’ to your .env file and check your Laravel logs for more detailed error messages.
Also, make sure you’re not hitting any rate limits or sandbox restrictions if you’re on a free Mailgun plan. Those can silently block emails without clear errors.
If all else fails, try swapping out Mailgun for a different mail provider temporarily, like Mailtrap. This can help isolate whether the issue is with your Laravel config or specifically with Mailgun.
Lastly, check your queue configuration if you’re using queued mail. Sometimes emails get stuck in the queue and never actually send. Good luck troubleshooting!
