What can I do to resolve undelivered email issues?

You can perform the following actions to resolve the issues related to undelivered emails:

• Check the Email Address: Verify the recipient’s email address for typos or outdated information.
• Reduce Attachment Size: Compress files or use file-sharing platforms like Google Drive or Dropbox for large attachments.
• Clear Spam Filters: Ensure your email content doesn’t trigger spam filters by avoiding suspicious language or attachments.
• Request Space in Recipient’s Mailbox: Ask the recipient to free up mailbox space if it’s full.
• Check Your Sending Reputation: Use tools like Sender Score or MXToolbox to ensure your sending IP isn’t blacklisted.
• Set Up Authentication (SPF, DKIM, DMARC): Proper email authentication improves delivery rates and proves your legitimacy.
• Wait and Resend Later: If the recipient's server is temporarily down, try sending the email again later.
• Review DNS Settings: Check your domain's DNS and MX records to ensure proper configuration.
• Contact the Recipient: Confirm that their mail server settings don’t block your email.
• Use a Different Email Address: If your address is blocked, send the email from another address or domain.
• Check for Authentication Errors: Ensure your email server is correctly configured and credentials are accurate.
• Address Rate Limiting: If you send bulk emails, slow the rate or use a professional service to avoid exceeding limits.
