Before proceeding with these steps, you must install the WP Mail SMTP by WPForms plugin. Please note that VentraIP is not in any way affiliated with the creators of this plugin.
The WP Mail SMTP by WPForms plugin reconfigures your WordPress website to send emails via an external SMTP service, which makes email deliverability much more reliable.
PHP Mail is the default option that WordPress would use if you didn’t have this plugin installed. SMTP.com, SendInBlue, MailGun, SendGrid and Google all require you to have an API Key for their service, which requires you to sign up for their service to obtain. AWS, Microsoft and ZohoMail are only supported by the premium/paid version of the plugin. Other SMTP is for when you want to manually input your own SMTP server details.
