Set Up an SMTP provider and DKIM Signature for email delivery

By default, WordPress uses the PHP mail function to send emails generated by WordPress. Zype does not support PHP email delivery. If you do not utilize an SMTP provider, your WordPress emails may not get delivered or will be filtered into the SPAM folder. To avoid this type, we recommend setting up an SMTP provider and a DKIM Signature within your WordPress site. 

What is SMTP?

SMTP (Simple Mail Transfer Protocol) is an industry-standard for sending emails. Proper SMTP configuration helps increase email deliverability by using authentication. 

What is DKIM Signature? 

DomainKeys Identified Mail, or DKIM, is a technical standard that helps protect email senders and recipients from spam, spoofing, and phishing. It is a form of email authentication that allows an organization to claim responsibility for a message in a way that can be validated by the recipient.

1) Set up an SMTP server so it's easier to configure the DKIM Signature, so the email will go through the SMTP instead of the PHP Mailer. Using the plugin WP Mail SMTP to integrate SMTP with WordPress is highly recommended.

WP Mail SMTP plugin includes many different SMTP setup options:

• SMTP.com (Recommended)
• Sendinblue SMTP (Recommended)
• Mailgun SMTP
• SendGrid SMTP
• Gmail SMTP
• Microsoft SMTP (Outlook.com and Office 365) [Pro]
• Amazon SES SMTP [Pro]
• Zoho Mail SMTP [Pro]
• All Other SMTP

2) Set up OpenDKIM. Here is a good tutorial.
