Is WordPress not sending email from your website?
This is a super common problem, and almost everyone with a contact form will run into this issue at some point. But it’s also really easy to fix.
We’ll show you the easy way to fix your WordPress emails in this tutorial.
Why Are My WordPress Emails Not Sending?
There are a few potential reasons why your WordPress emails aren’t sending:
- Your emails look like spam: This is the most common reason. When your web server generates an email, it only creates the headers required for basic email delivery. WordPress uses a function called
wp_mail()which doesn’t add any authentication to prove that the message is legitimate. You can use WP Mail SMTP to fix this.
- Your web hosting provider doesn’t allow you to send emails: This is less common, but it’s still an issue with some big hosts. You might run into this if you Amazon EC2 or Lightsail. WP Mail SMTP will allow you to get around this, with or without Amazon SES.
- You’re using localhost: If you’re creating your site on your computer before uploading it, your emails likely won’t work. WP Mail SMTP will fix WordPress not sending email on localhost.
Let’s go ahead and install WP Mail SMTP now.
How To Fix WordPress Not Sending Email
We’re going to use WP Mail SMTP to re-route your emails through a 3rd party email service provider (ESP). This will add the authentication required to get them delivered reliably.

- Connect Your WordPress Website to a Mailer Service
- Turn On Email Logging

Let’s install the plugin first.
1. Install the WP Mail SMTP Plugin
First, you’ll want to install WP Mail SMTP on your WordPress site. You can use the free or paid version, but you’ll want Pro or above to use the email logging and reporting features we’ll talk about later.
To download the plugin, head over to your WP Mail SMTP account and click the Downloads tab. You can download the plugin zip file by clicking Download WP Mail SMTP.
Next, switch to your website and log in to the WordPress dashboard. Head to Plugins » Add New.
Upload the plugin zip file and click Install Now.
Once the plugin is installed, be sure to Activate it. This will start the Setup Wizard in your browser.
Now we’re ready to set up your email provider for WordPress.
2. Connect Your WordPress Website to a Mailer Service
We’re going to route your emails through a separate email provider to fix WordPress not sending email.
With WP Mail SMTP, this is super easy to configure. We’re going to use the Setup Wizard so you don’t have to spend time playing around with the configuration settings yourself.
To start, click the Let’s Get Started button in the Setup Wizard.
On the next screen, you’ll see a list of available mailers that you can configure in WP Mail SMTP.
All of these providers will help fix WordPress not sending email. However, some of them aren’t suited to large volumes of email.
Here’s a quick guide if you’re not sure what to pick here:
- Small websites or testing: You can use Other SMTP for this. However, keep in mind that most SMTP servers have rate limits, so this could cause your WordPress emails to fail on a busy site. For an alternative option, Postmark and Sendinblue both have free trial accounts.
- Website sending a few emails a day: The Gmail mailer is a good option if you have a Google Workspace or Gmail account. It’ll allow you to send emails from any of your Gmail aliases in WordPress, which is handy if you want to use different Gmail aliases with different forms or plugins. Gmail and Google Workspace are a little bit more complicated to set up, though.
- Medium to large websites: Websites that send transactional emails should consider a professional email provider like SMTP.com or Sendinblue.
If you’re not sure what to pick, Sendinblue has a free plan for up to 300 emails a day. It also authenticates your domain name, rather than an individual email address, so you can send email from any address at your domain in WordPress.
You can sign up for the free plan without a credit card.
When you’ve chosen a mailer, jump to the documentation using the links below. The doc will help you set up a connection between your website and the mailer you chose in the Wizard.
|Mailers available in all versions||Mailers in WP Mail SMTP Pro|
|Sendinblue||Microsoft 365 / Outlook.com|
|Google Workspace / Gmail||Zoho Mail|

Our Elite license includes White Glove Setup for SMTP.com or Mailgun.
When you’ve set up a connection, switch back to this guide.
3. Turn On Email Logging
In the next step, the wizard will have two options enabled by default. They are:
- Email deliverability
- Error tracking
Both options will help in improving email deliverability.
If you have WP Mail SMTP Pro, you can enable the Weekly Email Summary and Detailed Email Logs here too.
So, how will this help?
First, our email log feature does a lot more than just WordPress email logging!
Once it’s enabled, you can also:
- Track opens and clicks in your WordPress emails
- See delivery status on a chart
- Store attachments in WordPress
- Resend or forward emails that failed
- Export sent emails in EML format
- Export logs in XLSX or CSV format
- Generate email reports
And the Weekly Email Summary will send you an update every Monday with deliverability statistics. This helps you to actively monitor your contact form emails to make sure you’re not missing any.
Now we’re ready to complete the Setup Wizard and test your email.
For the last step, grab the license key from your WP Mail SMTP account and paste it into the box to enable Pro features and future updates.
And that’s it! WP Mail SMTP will send a test email to confirm everything’s working.
Frequently Asked Questions About WordPress Not Sending Email
Got questions about WordPress emails not working? We’ll answer some common questions below.
- What Is SMTP?
- What Email Address Should I Use as the “From” Email?
- Can I Set Up WooCommerce SMTP?
- Why Can’t I Use PHPMailer?
- Why Is “Other SMTP” Not Working?
- Why Is “Other SMTP” Making My Site Time Out?
- Why Am I Seeing a DMARC, SPF, or DKIM Warning?
Let’s get started.
What Is SMTP?
SMTP stands for Simple Mail Transfer Protocol. It’s the protocol that servers use to send emails.
In WordPress, you can use SMTP to send emails instead of relying on your web server. This is more reliable because it adds the correct authentication to your emails.
What Email Address Should I Use as the “From” Email?
Many contact form plugins use the admin email as the From address. This can cause email deliverability issues.
Now that you have WP Mail SMTP installed, you should always use the From Email that you authenticated in the Setup Wizard. That will ensure that all of your emails have the correct authentication. In other words, the emails from WordPress will be delivered as though they were sent from your email account.
If you have a ton of different plugins all sending email, WP Mail SMTP allows you to force the From Email and the From Name across your entire site.
This is a super easy way to make sure you’re not sending email from a From address that isn’t authenticated.
Can I Set Up WooCommerce SMTP?
Yes! Once you’ve completed the steps in this tutorial, all WooCommerce order emails will be sent from your chosen mailer.
You can use an SMTP server for WooCommerce, but we recommend that you use a transactional email provider instead. This will make sure your customers get WooCommerce order emails quickly.
Why Can’t I Use PHPMailer?
PHP Mailer is the default method of sending email in WordPress. If PHP Mailer is selected in WP Mail SMTP, the plugin isn’t improving email deliverability at all yet. Essentially, it hasn’t been set up.
To stop your WordPress emails from going to spam, be sure to run the Setup Wizard and configure an email provider or SMTP server.
Why Is “Other SMTP” Not Working?
If the Other SMTP mailer isn’t working, or you’re getting an SMTP error, first check that you’re using the correct SMTP settings in WP Mail SMTP.
In particular, pay attention to the SMTP port since different servers have different requirements.
If that doesn’t work, you may be using a host that blocks SMTP or restricts you from using its own SMTP server. This block is typically put in place to prevent users from sending spam from WordPress, or to encourage you to pay for the host’s own SMTP service.
If SMTP is blocked by your host, you can use any of the API-based email providers like Sendinblue, SMTP.com, or Gmail to get around that. For more details, check out our articles on:
These guides are designed specifically for customers who can’t use SMTP to send email on their hosting plan.
Why Is “Other SMTP” Making My Site Time Out?
If the Other SMTP option is causing your WordPress site to time out, that’s a sign that you may have an incorrect DNS setting, or your SMTP server is down.
This is also a common issue for Cloudflare users who have the wrong proxy settings on their DNS zone. Check out this guide to fixing WordPress emails on Cloudflare for full details of the settings you’ll need to change.
Why Am I Seeing a DMARC, SPF, or DKIM Warning?
WP Mail SMTP has a Domain Checker that automatically scans your domain’s DNS records. If it spots a problem with your DNS that could affect email deliverability, it’ll notify you when you send a test email.
To fix this, start by reading our guides on DNS:
Once your DNS records are correct, your emails will have the right authentication and will no longer land in your recipient’s spam folder.
Next, Track Email Activity in WordPress
