If your emails are not sending, start by troubleshooting the most common issues:
1. Check Server Status: Verify if your email service provider's server is down. 2. Review Email List: Ensure that the email addresses are correct and up-to-date. 3. Inspect Sending Limits: Confirm you are within the sending limits set by your provider. 4. Validate Authentication Protocols: Make sure your DKIM, SPF, and DMARC records are correctly configured. 5. Optimize Email Content: Avoid spammy keywords and ensure your content follows best practices.
