You know the feeling. A customer says they sent you an email, but you can't find it. A password reset never arrives. An important invoice seems to disappear into the void.

The good news? Email rarely vanishes without a reason. Most missing email issues can be traced back to a handful of common causes.

Before contacting support, work through this checklist.

1. Check your Spam or Junk folder

This is the most common reason emails appear to be missing.

Modern spam filters are constantly evaluating incoming messages. While they're usually accurate, legitimate emails can occasionally get flagged by mistake.

Pay special attention if you're missing:

  • Password reset emails
  • Automated notifications
  • Messages from new contacts
  • Marketing newsletters you've subscribed to

If you find the email in Spam, mark it as "Not Spam" to help future messages arrive in your inbox.

2. Make sure your mailbox isn't full

Every mailbox has a storage limit.

Once that limit is reached, new emails may stop arriving or bounce back to the sender.

Signs your mailbox may be full include:

  • Receiving storage warnings
  • Missing incoming messages
  • Difficulty sending email

If you're close to your limit, delete unnecessary messages or increase your mailbox storage.

3. Review your email forwarding settings

Many businesses forward email from one address to another.

For example:

While convenient, forwarding doesn't always work perfectly. Some email providers apply additional filtering to forwarded messages, which can cause emails to be delayed or blocked.

If you use forwarding, send yourself a few test emails to confirm everything is working properly.

4. Add trusted senders to your safe sender list

If you regularly receive emails from a customer, supplier, or software platform, consider adding them to your safe sender list.

This tells your email provider that messages from that sender should be trusted whenever possible.

It's particularly useful for:

  • Clients
  • Team members
  • Banks
  • Software vendors
  • Online stores

5. Check for email filters or rules

Many email platforms allow users to create rules that automatically move, delete, archive, or forward messages.

Over time, it's easy to forget these rules exist.

Review any filters you've created and make sure important emails aren't being redirected somewhere unexpected.

6. Review your DNS settings

If your email stopped working after changing hosting providers, updating your website, or modifying your domain settings, DNS may be the culprit.

Incorrect email records can prevent messages from reaching your mailbox.

Common issues include:

  • Incorrect MX records
  • Missing email records
  • Changes made during a website migration

If you're unsure, your email or domain provider can help verify your settings.

7. Confirm the sender isn't having issues

Sometimes the problem isn't on your end.

Ask the sender to:

  • Verify the email address they used
  • Check for bounce-back messages
  • Resend the email
  • Try sending from another address

This can quickly determine whether the issue is with the sender or recipient.

8. When to contact your email provider

If you've worked through this list and emails are still missing, it's time to contact your provider.

They can review delivery logs and determine whether messages are being blocked, delayed, or rejected before they reach your inbox.

The bottom line

Most missing email issues come down to spam filtering, storage limits, forwarding problems, or configuration changes. Working through these checks can often solve the problem in minutes and help ensure you don't miss important messages in the future.
