How to Fix ‘Be Careful With This Message’ Error in Gmail (2021)

Are you seeing a yellow ‘be careful with the message’ warning in Gmail?

Gmail displays different variations of this warning if it thinks someone might be misusing your email address. Sometimes this can be a false positive.

In this article, we’ll explain how to set up your emails to reduce the number of Gmail errors or warnings.

Why Do I See ‘Be Careful With This Message’?

Google automatically adds ‘be careful with this message’ to emails that could be suspicious.

When Google detects a potentially malicious email, Gmail and G-Suite users see a warning in a colored bar at the top of the email.

Along with the warning, you might see text like:

  • This email claims to come from, but replies will go to an email address at another domain.
  • This may be a spoofed message. The message claims to have been sent from your account, but Mail couldn’t verify the actual source.
  • Gmail couldn’t verify that actually sent this message.

Sometimes senders will be marked with a question mark icon. When you hover over it, you’ll see the text  ‘ couldn’t verify that actually sent this message (and not a spammer)’.

If you’re seeing ‘be careful with this message’ warnings, don’t worry: your emails will likely still be delivered.

But any Gmail warning or error is still a problem because:

  • People might think your emails are spam or not trustworthy
  • They might hit the Report Spam or Report Phishing button in the warning box, which could cause problems with email deliverability
  • You might have missed a step when setting up your contact forms, and that could mean important messages are already being filed as spam.

You can’t shut these warnings off completely, but you can correct your email and contact form settings. This reduces the chance that your recipients will see them.

How to Fix ‘Be Careful With This Message’ Error in Gmail

We’re going to step through a 3-point checklist to reduce the Gmail errors you’re seeing.

  1. Check Your DMARC, DKIM, and SPF Records
  2. Check the From Address in All Plugins
  3. Use Different From and To Addresses

Let’s start with the most important.

1. Check Your DMARC, DKIM, and SPF Records

The WP Mail SMTP plugin lets you send emails from your WordPress site through a 3rd party mailer service. This is a great way to improve email deliverability from WordPress because these mailer services can apply verification to your emails.

But for this to work properly, you may also need to set up DMARC, DKIM, and SPF on your domain.

DMARC, DKIM, and SPF add verification data to the email header, which is the technical part of the email we don’t normally see. Without that data, Gmail will assume the email is suspicious because the From address doesn’t match the server that was actually used to send the message.

Email header example

You can run into this issue any time you use a 3rd party mailer service to send emails. For example, it’s also quite common when you send out email newsletters.

The best way to fix this is to check that your DMARC, DKIM, and SPF records are working.

Solution: Check Your DNS Settings

DKIM, SPF, and DMARC are TXT lines in your domain name’s DNS record.

To learn how to edit the DNS, check the documentation for your mailer service. If you’re using WP Mail SMTP, you can jump to the instructions using these links:

Review the requirements for setting up DMARC, DKIM, and SPF records, then check each record using MXToolbox to make sure it’s valid.

2. Check the From Address in All Plugins

In WordPress, you might have multiple plugins all sending emails using their own templates and settings.

For example, your contact form plugin and your backup plugin might have different From email addresses. One might be sending email from your preferred From address, but another might be sending emails from the site admin email address – or even a completely made-up one.

For example, Contact Form 7 defaults to using a From address of [email protected][your-domain], which is the default From address in WordPress.

To resolve email problems and make your WordPress site easier to manage, we highly recommend that all of the plugins on your website should use the same From address. This should ideally be an email address at your domain that actually exists.

Solution: Force the From Email in WP Mail SMTP

WP Mail SMTP makes it easy to send all of your emails from the same From address.

You can easily enable this by clicking Force From Email checkbox in the plugin settings.

When you click this, every plugin on your WordPress site will use the From address you’ve chosen instead of their own random or invalid address.

This helps to make sure that all of the emails from your site are validated.

If the Force From Email checkbox is grayed out, it means that your mailer requires this setting to be turned on and WP Mail SMTP has already taken care of this for you.

3. Use Different From and To Addresses

WP Mail SMTP has a test email feature that makes it easy to check that your WordPress emails are working.

But you might see a Gmail warning if you send the test email to the same email you used as your From address.

This can also happen with some plugins that send notifications. They might send emails to and from the same address like this:

Identical from and to addresses

This email has a G-Suite From address, but it isn’t sent from Google servers. So if you send it to yourself, it might trigger a ‘be careful with this message’ warning.

Nobody else will see this particular error, but it can be confusing because it looks like there’s a problem with your emails.

Solution: Use a Different Address for Testing

In WP Mail SMTP, try sending your test email to a different email address – not the From address you set up in the plugin.

This should remove the error and reassure you that your emails are working.

Additionally, if you’re seeing this error from specific plugin notifications, take a look and see if you can change the sender address for the notifications.

Here’s an example from MailPoet. In the settings, we can send newsletters from the From address that matches the domain, but we can also have plugin notifications sent to a different email address.

And that’s it! We hope these tips helped you to reduce the number of ‘be careful with this message’ warnings in G-Suite or Gmail.

  1. This doesn’t really do me any good at all and it’s a real pain. I run a small online store. I’m the only one in my “organization’ so ALL my emails come from outside my domain. Messages from MY online store all get branded with “Be Careful With This Message” that wastes space and takes time to get rid of. I really want to disable it but apparently I can’t.

    1. Hi Kent

      I’m sorry to hear you haven’t been able to resolve this issue on your site.

      This could be happening because you’re sending emails FROM and TO the same email address. For example, if your store emails are sending from “[email protected]”, and they’re also sent to[email protected]”, you’ll typically get this warning in Gmail. Nobody else will see this warning except you. If you wanted to remove it, you could change the FROM email to another valid email in WP Mail SMTP, which should stop it from happening.

      If everyone is seeing this message on your emails, it’s likely an issue with your DNS records. Our support team can help you to track this down. If you have a WP Mail SMTP license, you have access to our email support, so please submit a support ticket.

      Otherwise, we provide limited complimentary support in the WP Mail SMTP support forum.

      Thanks 🙂
