How Can I Troubleshoot Booking Emails Going to the Junk Folder or Delayed Delivery?

Booking confirmation emails are a vital part of using Booking.com and other external booking engines through Hosthub. However, customers may face issues such as these emails being misclassified as junk or spam or experiencing delays in delivery. Below is a guide to help troubleshoot and resolve these problems.

Common Email Issues

Users may encounter two primary email-related issues:

• Emails sent to the junk or spam folder: Sometimes booking confirmation emails are erroneously flagged as spam by your email provider.
• Delayed email delivery: Occasionally, there may be a delay in receiving the confirmation email after making a booking.

Troubleshooting Tips

1. Check Your Junk or Spam Folder

• Navigate to your email’s junk or spam folder to see if the booking email has been flagged incorrectly.
• If found there, mark the email as "Not Spam" or move it back to the inbox. This action will help train your email provider to recognize similar emails as legitimate in the future.

2. Verify Your Booking Details

• Ensure the email address provided during booking is correct.
• Double-check for any errors in spelling or formatting that might prevent the email from being delivered to your inbox.

3. Adjust Email Settings

• Review your email provider settings to tweak security or filtering rules.
• Add the email address used to send booking confirmations to your trusted contact list or address book.

4. Be Patient for Short Delays

• Sometimes, booking confirmation emails might take a few minutes to arrive, depending on the email provider or system load. If it does not appear promptly, recheck after a short interval.

5. Reach Out to Your Email Provider

• If issues persist, contact your email provider’s customer support for additional assistance. They can help you verify if emails are being blocked or filtered inaccurately.

Important: Do Not Mark Hosthub Emails as Spam

Marking Hosthub emails as spam can cause your address to be added to a bounce/suppression list, which then blocks all future notifications (including automated booking notifications) from being delivered.

• If you previously marked Hosthub emails as spam and notifications stopped arriving, this is likely the cause. Support can remove your address from the bounce list to restore delivery.
• Once unblocked, avoid marking these emails as spam again, as doing so can re-trigger the same blocking behavior.

Note: All Hosthub notifications, including automated booking notifications and human support replies, are sent from the same sender address ([email protected]), so no additional sender domain needs to be whitelisted.

If Automated Notifications Still Don't Arrive

Even when [email protected] is whitelisted and human support replies arrive correctly, automated notifications may still be filtered at a deeper level. Check:

• Server-side spam/quarantine (not just the inbox spam folder)
• Any security or filtering rules applied by your email provider
• Message logs at the provider level, if available

When to Contact Hosthub Support

• If you’ve followed all the steps above and still cannot locate or receive your booking emails, consider reaching out to Hosthub support. Provide details of the issue, such as your booking reference, email address, and any troubleshooting steps you’ve already taken.
