How to Set Up SMTP With FluentSMTP

Use this guide when you need to configure WordPress email delivery through FluentSMTP.

When to use this guide

For V2 sites hosted through 1ClickWebsite, SMTP is usually already configured for contact form emails. You usually only need to set up or change FluentSMTP if the site has been migrated to your own hosting, you are replacing the email sender, or support asks you to update the SMTP settings manually.

If you only need to choose which inbox receives contact form submissions, use this guide instead: How to Set Up Contact Form Emails.

What this guide covers

• Opening FluentSMTP in WordPress
• Adding an SMTP connection
• Entering sender and SMTP provider details
• Saving the connection
• Sending a test email to confirm delivery

Before you start

Have your SMTP provider details ready before you begin. You will usually need the SMTP host, port, encryption type, username, password, sender email, and sender name.

How to do it

1. Open your site in WordPress admin.
2. Go to FluentSMTP.
3. Add or update the SMTP connection.
4. Enter the sender and SMTP provider details.
5. Save the connection.
6. Send a test email from FluentSMTP.
7. Confirm the test email arrives in the inbox.

Notes

• The sender email should usually match the domain or email service you are using for SMTP.
• If the test email fails, recheck the host, port, encryption type, username, and password.
• If the SMTP settings are correct but emails still do not arrive, check spam or junk first.
• If delivery still fails after testing, contact support so we can review the site email setup.
