Mailgun-based invitation emails with dynamic parameters are not sending in my Laravel app despite correct settings. How can this be fixed?

Route::post('/invite-mail', [UserInviteCtrl::class, 'sendInvite']);

public function sendInvite(Request $req) {
    $inviteInfo = [
        'subject' => 'Welcome Aboard',
        'message' => 'Join our community now!',
        'receiver' => $req->input('user_email')
    ];
    
    Mail::send('emails.invitationTemplate', $inviteInfo, function($msg) use ($inviteInfo) {
        $msg->to($inviteInfo['receiver'])->subject($inviteInfo['subject']);
    });
    
    return redirect('/dashboard');
}

hey, try running php artisan config:clear and cache:clear, it worked for me. sometimes i had this issue when the env wasn’t updated correctly for mailgun. also, double-check you api keys and domain settings.

In my experience, the root of the problem was not always the Mailgun API keys but often a subtle issue with how the application handled the email data after a configuration update. I encountered a similar situation where after tuning the Mailgun settings, my email dispatch still failed because I overlooked a middleware caching issue. It helped to not only clear the caches but also to log responses from Mailgun to see if any parameter was rejected. Analyzing these logs provided key insights that eventually resolved the email delivery problem.

In my experience, the key to resolving this issue was to ensure that both the Mailgun configuration and the Blade template were correctly set up. I encountered a similar problem where a slight mismatch in the API credentials and an error in the email template syntax prevented emails from being dispatched. Verifying that the API key, domain, and endpoint details in your .env file are correct helped me. Additionally, inspecting Mailgun’s response logs provided insights that led to a quick resolution.
