Why should I use MailKing instead of MailChimp, Constant Contacts, or similar marketing software?

MailKing will send emails directly from your Gmail / Google Workspace account. This means that a major benefit of sending your email campaigns using MailKing, emails are not flagged as spam or marked as a promotion by your recipient's mailing service (Gmail, Yahoo, Office 365, etc.) as easily as a traditional email marketing software would be. This is because MailKing uses your Gmail or Google Workspace account to send emails, and not a commercial-use email server.

In other words, emails sent thru MailChimp, Constant Contacts, and others are often automatically marked as spam or promotion, whereas MailKing’s is not. This is because your recipients (and spam filters) cannot distinguish emails sent manually through Gmail from emails sent via MailKing.
