Incorrect SMTP server details, wrong port numbers, or outdated credentials can prevent invoices from being sent.</p> <h3 style="text-align: justify;" data-start="2291" data-end="2323">Internet or Network Issues</h3> <p style="text-align: justify;" data-start="2324" data-end="2448">Unstable or slow internet connections can interrupt the email-sending process, especially when invoices include attachments.</p> <h3 style="text-align: justify;" data-start="2450" data-end="2490">Firewall or Antivirus Restrictions</h3> <p style="text-align: justify;" data-start="2491" data-end="2590">Security software may block outgoing emails or attachments, mistaking them for suspicious activity.</p> <h3 style="text-align: justify;" data-start="2592" data-end="2615">Outdated Software</h3> <p style="text-align: justify;" data-start="2616" data-end="2729">Using an outdated invoicing or accounting application can lead to compatibility issues with modern email servers.</p> <h3 style="text-align: justify;" data-start="2731" data-end="2763">Email Provider Limitations</h3> <p style="text-align: justify;" data-start="2764" data-end="2857">Some email providers limit the number of emails or attachment size, causing invoices to fail.</p> <p style="text-align: justify;" data-start="2859" data-end="2974">If identifying the cause feels overwhelming, call <strong data-start="2909" data-end="2945">1-888-394-9046 or 1-866-596-1988</strong> for professional assistance.</p> <h2 style="text-align: justify;" data-start="2981" data-end="3042">Step-by-Step Guide to Fix Email Invoice Not Working Issues</h2> <h3 style="text-align: justify;" data-start="3044" data-end="3082">Step 1: Verify Email Preferences</h3> <p style="text-align: justify;" data-start="3083" data-end="3261">Check the email settings in your invoicing or accounting software. Ensure the sender’s email address is correct, credentials are updated, and the correct mail server is selected.</p> <h3 style="text-align: justify;" data-start="3263" data-end="3303">Step 2: Test Internet Connectivity</h3> <p style="text-align: justify;" data-start="3304" data-end="3431">Make sure your system has a stable internet connection. Try sending a test email without an attachment to confirm connectivity.</p> <h3 style="text-align: justify;" data-start="3433" data-end="3476">Step 3: Review Spam and Junk Settings</h3> <p style="text-align: justify;" data-start="3477" data-end="3600">Ask recipients to check their spam or junk folders. You can also ask your email provider to whitelist your sending address.</p> <h3 style="text-align: justify;" data-start="3602" data-end="3653">Step 4: Check Firewall and Antivirus Settings</h3> <p style="text-align: justify;" data-start="3654" data-end="3802">Temporarily disable firewall or antivirus software to test if they are blocking outgoing emails. Re-enable them afterward and add proper exceptions.</p> <h3 style="text-align: justify;" data-start="3804" data-end="3838">Step 5: Update Your Software</h3> <p style="text-align: justify;" data-start="3839" data-end="3971">Install the latest updates for your invoicing software and operating system.
