How To Configure WP Mail SMTP For Sendinblue Mailer – WordPress

Is your WordPress default PHP Mail Function not sending your emails? Are you unable to properly configure the WP Mail SMTP plugin for sending emails? Are you getting, “There was an error trying to send your message. Please try again later”? Are you getting “There was a problem while sending the test email”? You’re in the right place.
We will guide you step-by-step on how to install WordPress WP Mail SMTP plugin and how to configure the WP Mail SMTP for Sendinblue mailer.
WP Mail SMTP reconfigures the PHP function wp_mail() instead of the default PHP function mail() to use Gmail, Outlook, Sendinblue, SMTP.com, SendGrid etc. It creates an options page to manage the settings.
Sendinblue is one of the email services recommended by WP Mail SMTP. Sendinblue sends over 30 million emails each day. It offers 3 plans, one free and two paid. The free plan offers 300 free emails per day which is enough for any normal site. In case if your website needs more than 300 emails each day you can buy one of the other plans.
Why you need third-party plugins and email services for sending emails in WordPress?
- By default WordPress uses PHP mail function to send emails generated by WordPress or contact forms. Now the problem is that most of the WordPress hosting companies don’t have their servers properly configured for sending PHP emails. If the proper authentication isn’t there, then emails either go in the SPAM folder or don’t get delivered at all. Because of spam email issues WordPress allows to use third-party plugins like WP Mailer SMTP and mailers like SMTP.com, Sendinblue etc, to send emails.
