How to Setup SMTP for SendGrid WordPress for Better Emails

Emails are an essential part of operating a successful WordPress site. Whether you’re sending out newsletters, order confirmations, or other transactional emails, ensuring that your emails get delivered is crucial. One of the most effective ways to enhance email deliverability is by configuring an SMTP server. In this post, we’ll walk you through How to Setup SMTP for SendGrid WordPress to ensure they land in your users’ inboxes, not their spam folders.

What is SMTP and Why You Need It for WordPress?

Before diving into How to Setup SMTP for SendGrid WordPress, let’s first understand what SMTP is and why it’s so important for email deliverability.

SMTP, or Simple Mail Transfer Protocol, is the standard technology for sending emails over the internet. When you use SMTP, you authenticate and send emails through a designated email server, ensuring that emails are secure and reliably delivered.

By default, WordPress uses PHP mail to send emails. However, PHP mail can be unreliable and often leads to emails being marked as spam or not delivered at all. This is why configuring an SMTP server with a service like SendGrid can significantly improve the success rate of your emails reaching the inbox. Using SMTP for SendGrid WordPress offers the following advantages:

• Better Deliverability: Emails sent through an SMTP server, particularly from a trusted service like SendGrid, are less likely to end up in the spam folder.
• Authentication: With SendGrid, your domain and email server are properly authenticated, which reduces the chances of email rejection.
• Scalability: Whether you’re sending 100 emails a day or 100,000, SendGrid scales according to your needs.
• Analytics: SendGrid provides detailed analytics so you can monitor email performance, track open rates, bounce rates, and more.

Step 1: Create Your SendGrid Account

The first step to How to Setup SMTP for SendGrid WordPress is setting up an account with SendGrid. SendGrid offers a variety of pricing tiers, including a free plan that allows you to send up to 100 emails a day, making it an excellent starting point for smaller websites or blogs.

Here’s how you can create an account:

1. Visit SendGrid’s website and sign up for a free account.
2. Complete the sign-up process by entering your email address, creating a password, and filling out basic profile information.
3. After registering, you’ll be prompted to choose a plan. If you’re new to SendGrid, you can start with the free plan, which is ideal for small-scale email sending. As your website grows, you can upgrade to higher plans as needed.

Step 2: Generate Your SendGrid API Key

After creating your SendGrid account, you’ll need to generate an API key. This key will link your WordPress site with SendGrid, allowing it to send emails through the SendGrid SMTP server.

Here’s how to generate your API key:

1. Log into your SendGrid account and navigate to the dashboard.
2. From the left-hand menu, go to Settings and then select API Keys.
3. Click the Create API Key button.
4. Give your API key a name, such as “WordPress SMTP,” and select the appropriate permission level (full access is recommended).
5. Once you create the API key, make sure to copy it and save it somewhere secure. You will need it for the next step.

Step 3: Install and Configure the WP Mail SMTP Plugin

To connect your WordPress site with SendGrid, you’ll need an SMTP plugin. One of the best and most popular options is WP Mail SMTP by WPForms. This plugin allows WordPress to send emails via SMTP instead of relying on PHP mail, significantly improving deliverability rates.

Here’s how to install and configure it:

1. Log in to your WordPress dashboard.
2. Go to Plugins > Add New and search for “WP Mail SMTP.”
3. Click Install and then Activate the plugin.
4. After activation, go to WP Mail SMTP > Settings in your WordPress dashboard.
5. In the settings, you’ll need to choose SendGrid as your mailer. Select SendGrid from the available options.

Step 4: Enter the SendGrid API Key in WordPress

Once you’ve selected SendGrid as your mailer in the WP Mail SMTP settings, it’s time to configure it with the API key you generated earlier.

1. Paste your API key from SendGrid into the API Key field within the WP Mail SMTP plugin settings.
2. Set the From Email address. It’s essential that this email address matches the domain you authenticated with SendGrid (we’ll cover domain authentication in the next step).
3. Enter your From Name, which is the name users will see when they receive an email from you. This could be your website name or your personal name, depending on how you want your emails to appear.

Step 5: Authenticate Your Domain in SendGrid

One of the crucial steps to improve your email deliverability is domain authentication. When you authenticate your domain with SendGrid, it tells email service providers (like Gmail, Yahoo, etc.) that SendGrid is authorized to send emails on behalf of your domain. This step can drastically reduce the chances of your emails being marked as spam.

Here’s how to authenticate your domain:

1. In your SendGrid dashboard, go to Settings > Sender Authentication.
2. Click on Authenticate Your Domain.
3. Choose your DNS host provider (e.g., GoDaddy, Namecheap, etc.).
4. SendGrid will generate several DNS records (such as CNAME and TXT) that you’ll need to add to your domain’s DNS settings.
5. Log in to your domain registrar (e.g., GoDaddy or Namecheap) and add the required DNS records. Once these records propagate (which can take up to 48 hours), SendGrid will verify them.

Domain authentication is critical for the success of your email campaign. Once done, you will see improved email deliverability, as your emails are less likely to be flagged as suspicious.

Step 6: Test Your SMTP Setup

After completing all the previous steps, it’s time to test your SMTP setup to ensure everything is working correctly.

1. In your WordPress dashboard, go to WP Mail SMTP > Settings.
2. Scroll down to the Email Test section.
3. Enter an email address where you want to send the test email.
4. Click Send Email and check your inbox for the test email.

If the email arrives in your inbox, congratulations! You’ve successfully completed How to Setup SMTP for SendGrid WordPress for Better Emails.
