How to send emails in WordPress using SMTP

 In Developer, Email Deliverability

WordPress is one of the most popular open source Content Management Systems (CMS). Every fourth website created is on WordPress. No surprises there. It’s free to download, easy to use, SEO optimized and comes with 31,000+ plugins to increase functionality.

Configure WordPress to send emails

WordPress is more than just a blog publishing platform and is widely used by many to manage their business website.

Sending email is one of the important functionality that one looks for when using WordPress for business or blogging.

When you set up your WordPress site, you’ll want to include email sending functionality.  You can automatically send emails and seamlessly stay in touch with your website/ blog visitors. Whether sending a thank you message when a user subscribes, a confirmation email upon signup, an order confirmation email when someone purchases a product, sharing a forgotten password link over email, sending weekly newsletters, or more.

There are tools like MailPoet, Email Subscribers & Newsletters, WooCommerce etc. that can help you with your emails. Most of these tools use the default SMTP (Simple Mail Transfer Protocol, a communication protocol to transfer emails over the internet through your server) to send emails.

But it might not be a good idea to use the default SMTP.

Did you know that sometimes emails sent from your WordPress site might not be reaching your customers inboxes? Emails do not get delivered to the recipient because of the following reasons:

  • Email was sent but it went into the spam/junk folder on the recipient’s side
  • The server, port or firewall prevented the email from being sent
  • Email was lost somewhere on the server

Why choose Pepipost for sending your emails from WP Plugin

2. WP EASY SMTP

In the coming section, I’ll explain how you can integrate Pepipost with these WP SMTP plugins to send emails.

How to integrate Pepipost and WP MAIL SMTP

Sending emails through Pepipost using your WP Mail SMTP is quite simple. Here is the step-by-step guide:

1: Login to your WordPress account and install WP Mail SMTP plugin: https://wordpress.org/plugins/wp-mail-smtp/

2: Once installed, activate the plugin and click on the Settings link on your plugins page.

3: Enter the following details:

  • From Email: The from/ sender email address from where the email will be sent, example info@example.com. Note: the domain example.com needs to be pre-verified and approved by Pepipost. Login to your Pepipost account to add and verify your sender domain.
  • From Name: ‘From name’ is the first piece of information your subscriber sees in the inbox. Examples include Customer Care, Support Team, etc. This name helps identify the source of email and so it’s wise to choose this name carefully to get the best open rates.
  • Mailer: Select “Other SMTP”  to use Pepipost SMTP to send emails

  • Return Path: This is optional
  • Under Other SMTP Options, enter the following details:
    • SMTP Host: Enter “smtp.pepipost.com”
    • SMTP Port: Port can be 25, 587 or 2525. Many times the hosting providers block these ports for outgoing email. If none of these ports are working, you need to contact your web hosting provider to unblock these ports for sending outgoing emails.
    • Encryption: Default is “None”. Choose the SSL option. TLS is not the same as STARTTLS. For most servers, SSL is the recommended option.
    • Auto TLS: Keep it ON.
    • Authentication:
      • Username: Your Pepipost SMTP username.
      • Password: Your Pepipost SMTP password.
