Question: What ports should I use for different SMTP providers?**
Answer:
**Different providers use specific ports for secure email delivery:
Fix: Always use the correct port based on your provider’s security protocol to avoid connection errors.
Question: How can I test if my SMTP integration is working correctly?
Answer:**
**Send a test email from the SMTP settings page. If it’s delivered successfully, the configuration is correct.
Tip: If the test fails, recheck credentials, ports, and DNS records.
Question: I’ve entered all my credentials correctly, but I still get a “Connection Timed Out” error. What is wrong?
Answer: A “Connection Timed Out” error usually means your server or local network is being prevented from reaching the SMTP provider’s server. This is often caused by a firewall or your hosting provider blocking the specific ports required for email (like 25, 465, or 587).
How to fix it:
Fix: If the connection times out, try switching between Port 587 (TLS) and Port 465 (SSL). If neither works, contact your network administrator or hosting provider to confirm that outbound mail traffic is allowed.
Question: Does using a custom SMTP affect my “Unsubscribe” links?
Answer: No. Your system will still generate and manage the unsubscribe links. However, using a custom SMTP ensures that the “From” address matches your domain, which builds trust with your recipients and reduces the likelihood of them clicking the “Report Spam” button.
