How to Fix Emails from WordPress Not Sending on SiteGround

Are emails from WordPress not sending on your SiteGround website?

You might be having trouble with:

  • WordPress emails not sending after moving your site to SiteGround
  • Emails from WordPress contact forms going to spam.

We’ll walk you through the steps to fix both of these issues.

How Do I Send an Email From a WordPress Site?

You can send emails from WordPress using the WP Mail SMTP plugin. It improves email deliverability and it also gives you more control over the emails sent from your site.

On many hosts, wp_mail() doesn’t work so well because it doesn’t authenticate the emails WordPress sends. This typically causes them to wind up in the Junk Mail folder. Sometimes, the emails are discarded by email servers because they look like spam.

WP Mail SMTP reconfigures WordPress to use an external email service instead of the default wp_mail() function. That means every email generated by WordPress will have the authentication needed to get through spam filters.

Let’s move on and look specifically at WordPress emails not sending on SiteGround.

How to Fix Emails from WordPress Not Sending on SiteGround

Let’s walk through the steps needed to fix your WordPress emails on SiteGround.

  1. Check Your SiteGround Mailbox Quota
  2. Check Your Plugin Notification Settings
  3. Install the WP Mail SMTP Plugin
  4. Create SPF, DMARC, and DKIM Records in SiteGround DNS Zone
  5. Send a Test Email From WordPress

1. Check Your SiteGround Mailbox Quota

Are you trying to receive emails to a mailbox you created on SiteGround?

Unlimited email mailboxes are included on most SiteGround hosting plans, including:

  • Shared hosting
  • Managed WordPress hosting
  • Managed WooCommerce hosting

But on all plans, the maximum mailbox size you can create is 10,000 MB. If you manually set this to a lower amount, you’ll run out of mailbox space quickly.

Before diving into WordPress, it’s worth checking that your mailbox is correctly configured and has enough space to receive your WordPress contact form emails.

To start, log in to your SiteGround Client Area and click Websites.

SiteGround websites menu

From the sidebar, click on Site Tools » Email » Accounts.

Look for the email mailbox that you’re using to receive emails from WordPress. Click on the 3 dots on the right and click Change Quota.

You can also click Log in to Webmail and check the remaining allowance.

If everything looks OK here, let’s check your WordPress settings.

2. Check Your Plugin Notification Settings

For most users, the #1 issue is emails from contact forms going to spam.

If you’re having difficulty with a specific contact form plugin, we’ll help you review all of the settings to make sure the notifications are set up correctly. We created guides specifically for the most popular form plugins.

If you’re using a different plugin to send emails in WordPress, let’s install the WP Mail SMTP plugin on your SiteGround website now.

3. Install WP Mail SMTP

WP Mail SMTP will solve emails from WordPress not sending on SiteGround. You can use the plugin with free mailer services, or pay for an account if you need more capacity.

To start, download the zip file from your WP Mail SMTP account so you can install it on your website. You’ll find it in the Downloads tab.

Next, open up your WordPress dashboard. Head to the Plugins page and upload the plugin to your WordPress site.

If you’re not sure how to do this, check out this guide to installing a plugin in WordPress.

Install WP Mail SMTP

As soon as you activate the plugin, the WP Mail SMTP Setup Wizard will open.

You can also re-start the wizard at any time by clicking the Launch Setup Wizard button in your WP Mail SMTP settings. Just know that re-starting the wizard later might reset your SMTP settings.

Choose Your Email Service Provider

Now we can choose a new provider to handle outgoing WordPress emails.

Click the Let’s Get Started button to begin.

On the next screen, click the mailer you want to use in the list.

We recommend or Sendinblue because they’re reliable, and they’ll work well with most websites. In particular, these mailers are awesome for busy SiteGround sites that generate a lot of transactional emails.

If you have a small site, you can use Gmail or the Other SMTP server option.

The Other SMTP option lets you use any mail server that you already have access to. If you choose this option, be sure to enter the SMTP port carefully.

When you’ve chosen your mailer, open up our documentation to complete the setup steps on the provider’s side:

You can open the documentation in a new tab, then come back to this guide when you’re done.

At the end of the wizard, email deliverability and error tracking will be enabled. We recommend that you also enable Weekly Email Summary and Detailed Email Logs.

All set? Let’s quickly recap the DNS Zone settings in SiteGround and then run a final email test.

4. Create SPF, DMARC, and DKIM Records in SiteGround DNS Zone

When you set up your email provider, the documentation should have given you new DNS records that you need to create.

If you bought your domain from SiteGround, you’ll want to head to the Services menu.

SiteGround Services menu

From there, click on Domains.

SiteGround domains menu

The DNS Zone Editor will have a list of the records already created.

You can create new records in the main DNS Zone Editor screen. Be sure to click the correct record type from the tabs across the top.

Add new DNS record in SiteGround

We have a detailed guide that explains what your DMARC, DKIM, and SPF records do. For now, let’s quickly recap the settings so you can check them in the DNS Zone Editor.


DKIM electronically signs the emails sent from your domain. Some providers need a DKIM so the email header can be validated, which proves your message is genuine and not spoofed.


The SPF record lists the servers that are authorized to send email from your domain. Here’s an example of an SPF record that we checked in MXToolbox.

Valid merged SPF records in MXToolbox

It’s important that you only have 1 SPF record in your SiteGround DNS Zone.

You may already have an SPF record if you’re using other services with your domain. For example, if you’re sending monthly newsletters using an email provider service, you might have an SPF record for that already.

So to add your email provider, you’ll want to merge the new SPF record with the existing one.

To find out how to do that, read this simple guide on how to merge multiple SPF records.


A DMARC record is responsible for routing mail that’s been flagged as spam by the mail server. It also sends reports to tell you the outcome of spam filtering activity.

Example of a valid DMARC record

Your email provider should give you all of the details you need to create a DMARC record. If you need more help, check out this article on how to create a DMARC record. It includes a generic DMARC record that will work on most domains.


Some mailer services also require these records, although they’re less common than the other 3. If you don’t see these in your email provider’s setup instructions, you shouldn’t create them for emails.

Wait for your DNS Zone changes to propagate before moving on to the final step. This can take up to 48 hours.

5. Send a Test Email From WordPress

Now you’ve set up SMTP with your SiteGround WordPress site, let’s check that your emails are working.

To do that, head to the Email Test tab on your WP Mail SMTP settings page.

Test SiteGround email in WordPress

Now fill in the form and send the test email.

Send test email from WP Mail SMTP

Behind the scenes, WP Mail SMTP will run its Domain Checker and scan your DNS Zone. You should see a message with a green label to show that your SiteGround site is now sending email with the right authentication.

If you see a warning message, it could be because there’s an issue with your DNS Zone settings in SiteGround. The warning message will explain what you need to check.

  1. But where do I actually type in the SPF information? Been trying to figure this one out for quite a while now, and none of the tutorials seem to depict it…

    1. Hi Rafael,

      I’m sorry for any trouble finding where to add the SPF records.

      It depends on your host provider where exactly the SPF records will be added. In general, the SPF records will be added to your DNS settings, which you should be able to find in the settings for your website hosting provider.

      If you aren’t sure where to add these, please reach out to your hosting provider to see if they can guide you in the right direction or add the SPF records for you.

      If you need some extra guidance with this and 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 Lite support forum.

      I hope this helps!

      Thanks 🙂
